The T248X will communicate with either the DCS 300 Server or the Model 200 Controller. The DCS 300 Server is a new data collection server that replaces the Model 200 Controller. The Trakker Antares 248X family includes several rugged terminals:

	T2480 A programmable data collection terminal that has a serial port to transmit data to and accept data from a host or PC via RS-232 serial communications. With the optional Ethernet card, the T2480 can also transmit and receive data via Ethernet communications. The T2480 has a 4-line by 40-character screen.
	T2481 The only difference between this model and the T2480 is the screen size. The T2481 has a 12-line by 40-character screen that is configurable up to 25 lines.
	T2485 A programmable data collection terminal with the additional ability to communicate in Intermec’s 2.4 GHz radio frequency (RF) network. The T2485 provides wireless communications to a host either through the access points DCS 300 Server, 200 Network Controller, or directly through the access points. The T2485 has a 4-line by 40-character screen.
	T2486 The only difference between this model and the T2485 is the screen size. The T2486 has a 12-line by 40-character screen that is configurable up to 25 lines.

While scanning you hear three low beeps

You are scanning a configuration command to set one of the serial port parameters and hear three low beeps.

For example, you are trying to set EOM or SOM.

The order in which you scan serial port protocol configuration commands is important. The configurable serial protocol (CSP) uses EOM to determine the serial communications mode. When EOM is disabled, the terminal communicates in Character mode. When EOM is enabled, the terminal communicates in Frame mode.

To use Frame mode, you need to set EOM first. Next, configure Handshake, Configuration Commands Via Serial Port, LRC, SOM, and then Poll. To use Character mode, you need to disable these same parameters in reverse order.


Error message when exiting the Configuration Menu

You see this error message when exiting the Configuration Menu:

Commandname

command failed.

Remainder of configuration not updated.

The two-character name (syntax) of the configuration command that failed is listed on the first line of the error message. For example, you may see this message:

SS

command failed.

There may be a problem with the configuration due to a change made with the Scanner Selection (SS) command. Check the command listed in the message. Make sure the command is set correctly for the options and network communications you are using with the terminal.


Scanning Configuration Commands

You scan a configuration command, such as Keypad Caps Lock, and you hear three low beeps.

If you are working in the Trakker Antares 2400 Menu System, you cannot scan configuration commands. Use the Configuration Menu to change the terminal’s configuration, or exit the menu system to scan configuration commands.


Nothing happens when you scan a configuration command

You scan a configuration command, such as Keypad Caps Lock, and nothing happens. There are two possible solutions:

♦	You may have one or more reader commands disabled, such as Change Configuration, so that you cannot change the configuration. Enable all of the reader commands and try again.

♦	The terminal may be waiting for another command to complete the configuration change. If you started by scanning the Enter Accumulate command, you must finish the command by scanning the Exit Accumulate command.

a)	Scan the Enable Override to temporarily enable all of the reader commands.

b)	Enable Override

c)

d)	*$+DC3*

e)	Note: The resolution of this bar code may not be high enough to allow you a good read. Please see the user’s manual for a good copy of this bar code image.

f)	Disable the override so that your data is not interpreted as a command when you are finished.


RF and Ethernet Configuration Parameters

On the Trakker Antares with RF or Ethernet networks, you scan a configuration command to set one of these parameters and hear three low beeps:

♦	Controller IP Address or Host IP Address (TCP/IP)

♦	Terminal IP Address

♦	Default Router

♦	Network Activate

If the Network Activate command is enabled (2.4 GHz RF network enabled) while you are configuring a T248X with RF or Ethernet capabilities, these addresses must define a valid network configuration. For example, an invalid network configuration would be a server (or host) IP address set to 0.0.0.0 with the network enabled.

To set these four parameters, follow these steps

1.	Disable the Network Activate (NA) configuration command.

2.	Set the terminal IP address and the Controller IP address (or the host IP address for a TCP/IP network).

3.	Set the default router address (if necessary).

4.	Enable the Network Activate command.

You can change an IP address with the network enabled as long as it still defines a valid network configuration.


Auditory Problems and Solutions

You scan or enter an option for the Scanner Selection configuration command and you hear three low beeps.

You may have scanned or entered a Scanner Selection command that does not apply to the type of scanner or input device you have installed. You must set +0 SS0-SS6.


Network Connect Problems

If you are having any of the following error messages, click on the message to find some common solutions:

The Network Connect Status Light State

The Network Transmit status light is lit

The Network Connect Status Light blinks on the terminal screen

TCP/IP	Not connected to an access point.	Not used.	Connected to an access point.
UDP Plus	Not connected to an access point.	Not connected to the DCS 300 but connected to the access point.	Connected to an access point and the server.


The Network Transmit  icon is lit
The Network Transmit Status Light is Lit

The Network Transmit status light can be turned on in two instances:

♦	The Access Point is out of range of the T2485 or T2486

♦	There is data buffered in the RF or Ethernet interface waiting to be sent

The Access Point is out of range of the T2485 or T2486

In this instance, make sure that the T2485 or T2486 is within range of the Access Point.

♦	The T2485 or T2486 is not in contact with the access point. Make sure the access point is turned on and operating. You may also be using the terminal out of the RF range of an access point.

♦	In a TCP/IP direct connect network, you cannot scan or enter data when the T2485 or T2486 is not communicating with an access point or you may lose your TCP session. Try moving closer to an access point to re-establish communications.

♦	Make sure the T2485 or T2486 is configured correctly for your network. To communicate with the access point, the RF domain and RF security ID on the terminal must match the values set for all access points the terminal may communicate with.

There is data buffered in the RF or Ethernet interface waiting to be sent

This light is turned on when the data is buffered in the RF or Ethernet interface. The data is either waiting to be transmitted to the DCS 300 Server or host, or received data has not been accepted by the application on the T248X. When no data is being buffered in the interface, the Network Transmit status light is off.

♦	If the Network Transmit status light is on, the problem could be that the T2485 or T2486 is out of range of the access point. Move the T2485 or T2486 into the range or the access point to resolve the problem.

♦	If you have a T2480 or T2481, you might have a network traffic problem or the device might not be connected. Reconnect the device. If this does not resolve the problem, begin evaluating whether there is too much traffic being sent across your network.

♦	Check that nothing is blocking transmission to the server. Something might be interfering with the RF communications.


Network Connect icon blinks on the terminal screen
Network Connect status light blinks on the terminal screen

  See Also

On the T248X UDP Plus system, this problem means the terminal is not connected to the DCS 300. In the TCP/IP model, this error condition is not used.

In a UDP Plus network, the terminal is trying to establish communications with the DCS 300.

You can do the following:

1.	Check the T248X configuration.

2.	Verify that the access point is running and data collection is started.

The terminal may be out of range of an access point or the access point may have recently been turned off.

3.	Check that the access point is still turned on.

Run the access point diagnostic to determine whether you have a connection from the T2485 or T2486 to the access point.

4.	Verify that each device in the network has a valid IP address.

Each device in the 2.4 GHz RF or Ethernet network must have a valid IP address. The IP addresses set on the terminal must match the addresses configured on the server or host.


Unable to establish a connection to the host

  See Also

The Network Connect status light blinks on the terminal screen and you see this message:

Unable to connect to server.

Error 102.

Unable to establish connection to host.

Session ended.

The T2485 or T2486 is connected to the access point, but is trying to establish communications with the DCS 300 and the host computer. Make sure the terminal is correctly configured for your network. Make sure the server is configured and running. Make sure the host computer is configured and running.

If you have configured the network correctly, try restarting the server to establish communications. You can also try resetting the terminal.


The Network Connect status light remains on, but the host computer is not receiving any data from the T248X

  See Also

There may be a problem with the connection between the DCS 300 and the host computer (UDP Plus). Check with your network administrator or use the DCS 300 System Manual to troubleshoot any potential problems on the server.

In a TCP/IP network, there may be a problem with the connection between the access point and the host computer. Check with your network administrator or use your access point user’s manual. The Network Connect status light remains on, but you cannot establish a terminal emulation session with the host computer.

There may be a problem with the Ethernet network and the connection between the terminal and DCS 300 or host. Check with your network administrator. Try restarting the DCS 300 or terminal.

There may be a problem with the host computer, a problem with the connection between the DCS 300 and the host computer, or a problem with the connection between the access point and the host (TCP/IP). Check with your network administrator to make sure the host is running and allowing users to login to the system.

When you turn on the terminal after it was suspended for awhile (10-15 minutes or longer), the terminal can no longer send or receive messages over the network. The host may have deactivated or lost your current terminal emulation session. In a TCP/IP direct connect network, you need to turn off the “Keep Alive” message (if possible) from the host so that the TCP session is maintained while a terminal is suspended.


Problems Transmitting Data Through the Serial Port

  See Also

If you are having problems sending or receiving data through one of the serial ports on the Trakker Antares 248X terminal, check these possible problems:

♦	Make sure the terminal is connected to the host computer or serial device.

♦	Make sure you are using a null-modem RS-232 cable to connect the terminal to the host or serial device.

♦	Make sure the terminal’s serial port parameters are configured to match the serial port configuration on the host computer or serial device. For example, make sure the baud rate is the same.


Problems Using the Screen Mapping Application

  See Also

There are three types of errors that you may see while running the screen mapping application on the Trakker Antares 248X terminal:

♦	Initialization errors that occur while trying to start the screen mapping application, download the template, or loading a screen.

♦	Communications errors that occur while trying to communicate with the DCS 300.

♦	Data entry errors that occur while entering data in the fields on a screen.

Input device attached to the terminal does not work well and will not read bar codes quickly.
Input device attached to the terminal does not work well and will not read bar codes quickly

Reads should occur quickly when you use any of the Trakker Antares 248X devices. When reads do not happen quickly, you could have problems with the symbology selection or the quality of the label you are trying to scan is inadequate.

Try the following

Set the Scanner Selection command to the specific input device connected to the terminal.

♦	Enable only the symbology you are scanning.

♦	Check label quality.


Input device will not read the bar code labels

Try the following tests to see if you can make the scanner function correctly

1.	Aim the scanner beam so it crosses the entire label in one pass.

2.	Try scanning the bar code label again, but vary the scanning angle.

The bar code label print quality may be poor or unreadable. To check the quality of the bar code label, try scanning a bar code label that you know scans. Compare the two bar code labels to see if the bar code is damaged or of poor quality.

3.	Enable only the bar code symbology you are scanning.

From the Symbologies Menu, each enabled symbology has an asterisk (*) next to it.

4.	Run a scanner diagnostics test to check the laser scanner.


Problems scanning bar code labels

If you  attempt to scan using the badge scanner or other scanning device and nothing happens, check the terminal for these possible problems.

Problem	Solution
Input device or badge scanner does not appear to be working.	1. Make sure that the terminal is on. 2. Make sure that the connector is still attached inside the back panel. Note: Unless you secure cables correctly using cable restraints, the cables can fall off.
You scan a reader command, such as Backlight On, and nothing happens.	The reader commands are disabled. Scan the Enable Override command shown here to temporarily enable all of the reader commands. You can also enable or disable reader commands with the Trakker Antares 2400 Menu System. When you are finished, remember to disable the override so that your data is not interpreted as a command. Enable Override *$+DC3* Note: The bar code shown here will not be of sufficient resolution to scan. Refer to the User’s manual for a version of this bar code that is usable.
You scan a valid bar code label to enter data for your application. The data decoded by the scanner does not match the data encoded in the bar code label.	The terminal may have decoded the bar code label in a symbology other than the label’s actual symbology. Try scanning the bar code label again. Make sure you scan the entire label.  To operate the terminal quickly and efficiently, you should enable only the bar code symbologies that you are going to scan. If you enable multiple symbologies, the terminal may on rare occasions decode a bar code according to the wrong symbology and produce erroneous results.
You want to set the terminal back to the default configuration to start over configuring the terminal.	Scan this bar code label: Default Configuration *.+* *.+* Note: The bar code shown here will not be of sufficient resolution to scan. Refer to the User’s manual for a version of this bar code that is usable.

Task Status

  See Also

A programmer can use the Task Status screens to view the task name, stack, and the percentage of time a task has been running. You can also use the Task Status screen to determine the type of RF network protocol, TCP/IP or UDP Plus, loaded on the terminal.

The %Time field measures the relative amount of time that a given software task or component is active. For example, Idle Task (ID) in the Power Management software is a component. The %Time that Idle Task is active is directly proportional to battery life.

You can also check the task list to determine the RF network protocol loaded on the terminal. Check the list of task names for UDP+ or TCP/IP. A task name of UDP+ means the terminal uses the UDP Plus protocol for RF communications. A task name of TCP/IP means the terminal uses the TCP/IP protocol for RF communications.

To refresh the statistics and start from a known point in time, use the Clear Task Profiles diagnostic option to clear the task status counters.

To run the Task Status Test

1.	From the Diagnostics menu, select Software Diagnostics and press Enter (;).

2.	Select Task Status and press Enter (;).

3.	Press Enter (;) to review the results on subsequent screens.

Problems Using Terminal Emulation Applications

There are two types of error messages that you may see while running the 3270, 5250, or VT/ANSI TE application on the terminal:

♦	Recoverable error

♦	Non-recoverable error

Recoverable errors display in the status line on the bottom line of the terminal screen. If the status line option is not currently selected, the status line will appear if there is a recoverable error. A non-recoverable error appears directly on your screen and your TE session ends. You must follow the instructions on the terminal screen to continue with your session.

If the DCS 300, Model 200 Controller, or host detects an error and ends the session, you will see a controller or host error message on the terminal screen. Record this error message and pass it on to your network administrator or contact your local Intermec service representative.

The 3270, 5250, and VT/ANSI TE applications have an error handling routine that detects local editing errors and command handling errors. If you have a problem while running your TE application, check these possible problems.

Note: Many of the error messages in the next table only apply when running the 5250 TE application.

You press a 3270 or 5250 command on the keyboard or keypad or scan in a command and the TE application does not respond.	The key mapping file does not match the TE application. From the list in Appendix A, find the correct key mapping file and download it from the DCS 300 or Model 200 Controller or from the directory where you installed the firmware upgrade. For example, if you are running the 3270 TE application, you need to download the POLX3270.MAP key mapping file. The key mapping file must be stored on drive C.
In a TCP/IP network, you turn on the terminal after it was suspended for awhile and the host has deactivated or lost your current terminal emulation session.	You need to turn off the “Keep Alive” message from the host so that the terminal emulation session is maintained while a terminal is suspended.


Problems Connecting to a Host

This section explains how to respond to error messages indicating that the terminal is not communicating with the DCS 300, the Model 200 Controller, or the host. You will need to know detailed information about your network, such as the IP addresses your network uses

Error Message or Problem	Solution
Unable to connect to controller. Waiting for connection to controller ... Unable to establish connection to host. Restarting Terminal Emulation. Please Wait.	Make sure the terminal is correctly configured for your network. You must set the network parameters, such as Network Activate and the network IP addresses, before the terminal can communicate with the host. For help, see your Trakker Antares user’s manual. If the terminal and network parameters are set correctly, the terminal is running a TE application that is not compatible with your network protocol (TCP/IP or UDP Plus). To fix the problem, you need to download the TE application that matches the terminal’s protocol. Use the Trakker Antares 2400 Menu System to determine the network protocol and TE application loaded on your terminal. In File Manager, check the type of TE application by using the list of “Terminal Emulation Files” in Appendix A. To determine the network protocol loaded on the terminal, use the Primary Network option on the Configuration Menu. You have UDP Plus if the Primary Network screen shows Controller IP Address. Otherwise, the terminal is using the TCP/IP network protocol. For example, you have a terminal loaded with the TCP/IP network protocol and the TE application on drive C is PLX3270.BIN. You need to download the TCP3270.BIN file to the terminal and delete the UDP Plus TE application, PLX3270.BIN. You can download the TE applications from your DCS 300 or Model 200 Controller or from the directory where you installed the firmware upgrade.
	To download and run a new TE application 1. Connect the terminal to your PC, DCS 300, or Model 200 Controller. 2. Download the application to drive C. 3. Press )ww;wwTwww2wwwM to access the Trakker Antares 2400 Menu System. 4. Choose System Menu and then choose File Manager. 5. Select drive C. 6. Delete the incompatible TE application by highlighting the application and pressing ) .. 7. Highlight the TE application you downloaded and then press ;. The terminal boots, resets all firmware, and runs the new TE application.


Problems Accessing the TE Configuration Menu

This section explains how to get to the TE Configuration menu and how to configure your terminal to recognize keypad commands specific to terminal emulation.

Error Message or Problem	Solution
You press ( ¡ to access the TE Configuration menu and nothing happens.	To access the TE Configuration menu, you must be in a TE session or at the TE welcome screen. To get to the TE welcome screen when you are not in a TE session, scan Reset Firmware and press ( ¡ when the TE welcome screen appears.

The Trakker Antares 248X consists of the following elements:

♦	Main board assembly

♦	I/O board assembly

♦	Keypad assembly

♦	LCD assembly with a liquid fluorescent display

♦	LED assembly

♦	7.2V, 700mA hour NiCad battery pack

♦	Antenna assembly for the RF version

♦	Speaker assembly

♦	LCD backight inverter module

♦	Optional badge scanner module

The two board assemblies are called “main” and “I/O” boards. The main processing and power supply functions are done on the main board. The main board is connected to the I/O board through two 30-pin flat flex cables. There is also a power cable from the I/O board to the main board that brings +12V power and backup battery power to the main board.

Two I/O boards are available for any of the 248x models. These I/O boards are described as follows:

Standard I/O	This board contains 1 serial COM port and connectors for an internal and an external badge scanner.
Enhanced I/O	This board contains 3 serial COM ports, digital output relays, and connectors for an internal and an external badge scanner.


Main PCB Assembly

 See Also

The main PCB contains the primary circuitry to run the TRAKKER ANTARES 248X software. It is also designed to be used as the main board for the T2455 Vehicle-Mount Terminal, so it has extra functionality to accommodate the special requirements of the T2455.

The functions of the main PCB are:

♦	Processing keypad input

♦	Processing output data to the liquid crystal display (LCD)

♦	Decoding bar code data at the scanner interface

♦	Providing radio communication interface (T2485/6 only)

♦	Enabling COM1, COM2, and COM4 interface to the I/O board. COM2 and COM4 are only available in the enhanced I/O board

♦	Controlling four digital output relays

♦	Sensing voltage changes at the four optically isolated inputs

♦	Providing Ethernet communications as one of the options in models T2480 and T2481

♦	Providing uninterrupted operation during AC power glitches (of up to 4 second) using a large backup battery.

♦	Providing non-volatile RAM to store display temperature compensation table and previous battery usage history in a Serial EEPROM (U6).

The main PCB also provides interfaces to the backup battery, T2455 DC power supply interface support, and external AC to DC converters to power the battery chargers and to power the main PCB externally.


Microprocessor

 See Also

The Vadem VG-230 is based on the NEC V30HL 8086 CPU core, which provides PC/XT-compatible core logic. The VG-230 uses a single bus architecture requiring only one address and one data bus.


Memory Map

 See Also

Up to 1MB of directly addressable memory space is supported by the V30HL. The VG-230 provides access to additional memory space through 26 mapping registers. Each memory mapping register controls a 16K block of memory. The bottom 512K of the RAM array are always mapped to the base 512K of the 1MB memory space of the V30HL. The top 32K of the RAM array are always mapped to the CGA BUFFER area of the 1MB memory space of the V30HL. Finally, the bottom 64K of the heavy access ROM array are always mapped to the top 64K of the 1MB memory space of the V30HL or ROM BIOS.


Oscillators

 See Also

The Vadem VG-230 requires two crystal oscillators. The primary crystal frequency for the CPU oscillates at 32.215905 MHz. Two footprints are provided so that two different manufacturers can provide crystals. The sources of crystals cannot be mixed, so at any given time only one source is used.

The 32.215905 MHz clock is buffered through a fast inverter U17A before it is routed to ASICA. The count gathering circuitry uses this clock to capture scanner input.

The second crystal oscillates at 32.768 KHz and provides frequency for the real time clock included in the VG230. The 32.768 KHz uses a fundamental design with a variable capacitor to achieve the accuracy setting required. This clock is kept running when the main power fails and the system is powered from the backup battery.


Flash Memory

 See Also

The main PCB was originally designed to support 2MB of flash memory. To support the Asian character set (double-byte fonts), the main PCB was designed to accommodate an additional 2MB of flash memory. The following memory configurations are supported on the main PCB:

♦	2MB - one 16M-bit flash (28F016SA)

♦	4MB - two 16Mbit flash (28F016SA)

♦	4MB - one 32Mbit flash (DD28F032SA)

The flash memory selected for the main PCB provides very high read/write performance. The flash memory also features advanced write state machines.

The main PCB supports these additional features:

♦	An ASIC-controlled boot address (BOOT-ADDR) signal for boot block swapping, allows the boot block to be reprogrammed and the check sum validated before the new boot block is used. The boot logic allows recovery in the event that Flash boot block reprogramming is interrupted. This is accomplished by using a programmable inverter on address line 16 to Flash which interchanges adjacent 64K Flash blocks.

♦	A CPU reset, which initializes the programmable inverter, will always reset it to bank a 64K block containing a small 4K boot kernel. This kernel initializes the registers and calculates a checksum for the portion of Flash that will be banked in at run time. This 4K start-up code is factory programmed using the in-circuit test and is only updated at an Intermec repair center.

If the ROM checksum passes, the run-time portion of the Flash is banked in to replace the boot kernel; if the checksum fails, the kernel goes into a bootstrap mode to download loader code from either the optical interface serial port, or the input device serial port.

♦	An ASIC-controlled write protect (WP*) signal for controlling unwanted writes to the Flash memory.

♦	Support for +12V programming voltage Flash devices

However, with an alternate stuffing of components, +5V programming voltage flash devices could be supported when the +12V parts become obsolete (a new version of system software will be required for this change.)


Pseudo Static RAM

 See Also

Two 512K Pseudo Static RAM devices are used in the main PCB to provide 1MB of RAM. The Pseudo Static RAM is powered by VCC230A. When the main PCB is in Suspend mode, the ASIC generates self refresh (SELF-REF*) to maintain memory. This feature was not supported in the original VG-230 architecture.


Operating States of the System

 See Also

A power management unit (PMU) is embedded on the VG-230 device. For detailed information, refer to the VADEM VG-230 Sub-Notebook Engine, Technical Reference dated October 1992. This device is used to slow the CPU and bus clock speed, and to shut off peripherals to reduce power consumption. The PMU implements 5 power states; they are:

ACTIVE

SLEEP

DOZE

 SUSPEND

OFF

ACTIVE state allows the clock to be at full speed.

SLEEP and DOZE state are slow clock operating modes. SLEEP and DOZE can provide the same level of functionality and are only differentiated by the selection of peripherals that are shut down. The terminal only uses DOZE mode which is renamed STANDBY state.

SUSPEND is a non-operating state in which all clocks with the exception of the RTC clock are shut down. Power is only maintained to the VG-230 and the RAM in SUSPEND.

OFF state only differs from SUSPEND state in that RAM power is shut off. An Antares terminal uses both SUSPEND and OFF states depending on the device configuration.

When in STANDBY, control logic in the PMU monitors interrupts and DMA. It automatically goes into fast clock mode upon occurrence of an interrupt and a DMA request.

After the interrupt is serviced or the DMA operation completes, slow clock mode will resume unless explicitly commanded into ACTIVE state by software.

The PMU provides activity monitors, I/O traps, and a series of timers to facilitate transparent power management. All Antares applications are power-aware and do not make use of transparent power management hardware. All power state transitions with the exception of SUSPEND to ACTIVE, and momentary fast clock transitions are explicitly commanded by software.

Power state summary:


Serial EEPROMS

 See Also

A 4 Kbit serial EEPROM (U6) is used to store LCD temperature compensation table and constants that might differ between the T248X Stationary Terminal (FMT) and Vehicle-Mount Terminal (T2455) products.

The Serial EEPROM can be accessed by both the Main and PIC processors. The predetermined data is written to the EEPROM by the system software during the software load process. PIC accesses the information as needed. The EEPROM serial protocol is I2C.

I2C is a two wire synchronous serial bus standard developed by Phillips electronics. It allows bi-directional communication between multiple peripherals.

Some of the serial EEPROM’s memory is used to log event data collected by the PIC. The PIC writes data to the serial EEPROM to tracking of errors and operating conditions. It can be uploaded using a diagnostic utility for use by engineering and maintenance personnel.

The logged events are:

♦	The minimum and maximum temperature unit has operating at measured by the PIC on the main board thermister.

♦	The number of times that the backup battery charge cycle is completed.

♦	The number of times that the terminal cold boots. A cold boots occur if all power is removed, if the reset switch is pressed, if the on/off switch is pressed at the boot screen, or if the PIC watchdog fires.

♦	The number of times that an I2C error events. The I2C error counter is incremented if ASIC master and PIC master try to operate at the same time. An I2C error can also occur or if a slave device such as the serial EEPROM or the I2C T2455 bus expansion chip is found in an invalid state that keeps the I2C data line pulled low.


Scanner Interface

 See Also

The scanner interface signals, GOODRD*, LASEN, VIDEO, SOS, AND CG-GEN-CNTL are all handled by ASIC A. These signals are used to start and stop the scanning process. The video signal is broken down by the ASIC and the bar code data is directly put into memory by the DMA process by ASIC A. The signal CG-GEN-CNTL enables the use of the competitive scanners (Symbol laser scanners.)


Status Light Emitting Diodes (LEDs)

 See Also

The LEDs assembly (on the front of a T248X) plugs into the J3 connector. The functions of these LEDs are explained in the user’s manual.

Six of the LEDs are controlled by a serial protocol through the ASIC B . Serial data, LED-DATA is sent to U37 (a serial to parallel shift register) where it is shifted to parallel arrangement by LED-CLK signal. Then the data becomes latched by U36 using LED-LATCH signal in order to drive the LEDs directly.

The power LED is driven individual from ASIC B in order to for software to have more flexibility in control of this LED.


Keyboard Interface
Keypad Interface

 See Also

VG230 provides two types of Keypad subsystems:

PC/XT serial keypad interface to connect to a standalone PC/XT keypad subsystem

Internal Keypad Scanner to control switch matrix.

The first option is used in the T248X. The keypad plugs into connector J11. The signals KBCLK, KBDATA are the serial interface to the keypad matrix.

The third signal ON-SWITCH becomes high when the œ key is pressed on the keypad assembly. The unit turns on if it is suspended and suspends if it is turned on.

The ON-SWITCH is connected to the ON/OFF input of the ASIC A (pin 84) and pin 26 of POWER-MON PIC.


Liquid Crystal Display (LCD) Interface

 See Also

The VG-230 supports signals FRAME, LOCLK, M, LCDU(0-3), and SHCLK for the LCD interface. Discrete signals to the LCD include LCDEN, VPBIAS, LCD-CTRL, and LCD-ADJ.

Backlight is powered from VLUMP, and is turned off when the VLUMP (external power) is removed. The backlight is also controlled by VPSYS, so the backlight is turned off when the unit is suspended.

The LCD is powered from the VCCLCD which is switched from VCC230A with the VPLCD signal.

The LCD also requires a negative BIAS voltage (-VLCD) which is generated from VCCLCD by a switching power supply (U35, U12 and L5). Varying -VLCD changes the LCD contrast. The output of the BIAS voltage regulator is digitally adjustable using a two TTL inputs. Method of adjust is compatible with the Maxim MAX749 (U35) Digitally Adjustable LCD Bias Supply. Bias voltage is adjusted as follows:

Software expects 64 contrast adjustment steps. The contrast step is reset to step 1 when incremented from step 64. Contrast is decremented one step by incrementing 63 steps.

The LCD contrast changes with temperature. At very high and low extremes, the LCD can become unreadable. To avoid this problem, the Feed-Back (FB) signal to U35-pin 4 can be changed with temperature change to compensate for the temperature changes. The FB voltage is manipulated by a Pulse Width Modulator (PWM ) formed by the signal PWM-TCOMP and resistor R103 and capacitor C116.

The signal PWM-TCOMP is generated by the POWER-MON PIC. Its pulse width is picked from a configuration table stored in the Serial EEPROM. The values in the configuration table were determined by experimentation during the product development phase.


PC Card Interface

 See Also

The VG-230 supports up to two PC card interfaces compatible with the PCMCIA version 2.0 standard. Interfaces supported are:

♦	Approved sources of NEC-2000 compatible Ethernet cards

♦	Up to 64MB of SRAM memory

Even though the PC card interface meets the PCMCIA version 2.0 standard, the Trakker Antares software includes software enablers for certain PC cards that have been tested by the development team can be plugged in. Software driver enablers are not available for all the commercial PC cards.

Slot A is dedicated either to the Radio or Ethernet cards. The Memory type of cards will be always placed in the second slot (slot B).

PC card A is powered by VCCRF which is filtered VCC supply, and the power to this card slot is removed when the system suspends.

PC card B is powered from VCC-CRDB which is powered from VCC230A through the FET switch U8. The switch U8 is controlled by logical OR of VPCRD and VPSYS. Thus, it is possible to leave this power on when the unit is suspended. This is a provision for future memory card applications. The system software can be set to leave this switch on at suspend via a “Hardware Configuration Table” which is downloaded to each unit in the factory.

Reset is an open collector signal generated from RESOUT* per the PCMCIA specification.

The PC card programming voltages VPPA (for Card A) and VPPB (for Card B) are switched from VPP with signals VPPENA and VPPENB (respectively). VPPA and VPPB are also wire OR'd with the respective card’s VCC line per the PCMCIA specification.


Speaker Driver

 See Also

Control signals BEEP0 and BEEP1 drive two 4 to 1 multiplexers (in DG509) to produce an AC waveform that is amplified by an operational amplifier in order to drive speaker. In the front of the case. BEEP0 and BEEP1 are produced by the ASIC by setting the control registers in the ASIC. Volumes produced are off, low, medium, medium high, and high. Sound frequency is the same as the frequency at which BEEP0 and BEEP1 are toggled.


ASIC

 See Also

Terminal specific functionality is implemented in an ASIC. The ASIC provides all digital logic necessary to implement terminal functionality. The general block diagram of the ASIC is shown below. T248X includes two of the same (vs. one which is used in the T242X.)

The main ASIC (ASIC A, U36) provides the following functions:

♦	A second 8250-compatible UART. The UART clock is generated by dividing the 3-68MHZ clock.

♦	Count gathering logic for scanner decoding

♦	The Beep control allows beep duration to be set in hardware. An interrupt sharing multiplexer is provided that routes multiple interrupts to a single input (IRQA) to VG-230’s 8259 interrupt controller.

♦	Control signals LED-DATA, LED-CLK, and LED-LATCH for the LED assembly.

♦	Creating EKT signal in response to an œ press.

♦	Control SW-RWR-ON

♦	A means for the system software to recognize that this is an stationary unit vs. a portable.

Below is the block diagram of the ASIC.

ASICB (U14), (which is the same port as ASICA U36), is used in this unit to provide the following functions:

♦	A third 8250-compatible UART. The interrupt generated from this UART (COM-INT is connected to the ASICA’s EXT-INT1.

♦	A logic interface to control the output relays on the I/O PCB.

♦	Miscellaneousellaneous control signals related to enabling COM port interfaces.

♦	ASICA and ASICB addresses are differentiated by inverting address line A9.


Power System

 See Also

The terminal power system has two main power sources: External Power Supply and Backup Battery. The external power supply (Lump) functions as the primary power source. The backup battery is a NiCad battery and provides energy when the system loses external power. The NiCad battery will run the system for 4 seconds after removal of the external power supply (except the backlight). If the power is removed more than 4 seconds, the system will suspend and the system will only store data and run the real time clock.

Both the lump and the backup pack are connected to the I/O board. The power is cabled to the main board through connector J8. The backup battery is switched in through U33 when there is a valid VCC230A voltage present. This feature will prevent the battery from being totally discharged when the external power is removed for a long period of time.


NiCad Backup Battery

 See Also

The backup battery is a rechargeable NiCad battery that is recharged from the external power supply. The NiCad battery consists of six 1.2V NiCad AA cells connected in series. Specifications on the NiCad battery are: 7.2V nominal voltage, 700 mAh nominal capacity. The NiCad battery is charged to 8.3V with a maximum charge rate of C/10 (70 mA.)

The capacity status of the battery is determined by the U15 the power monitor PIC processor. The output voltage of the battery is determined by measuring the voltage when a 75mA load is applied. The load is applied when the BB-LOAD signal goes high and turns the transistor Q18 on which is loaded by resistors R227,205 and 207. BB-Load is turned on by U15 every few minutes.

If the battery voltage is 7.2V or below, U-15 applies BB-CHG signal to turn Q2 on. The current to the battery is sensed by OpAmp U9 and resistor R203 and is limited to 70mA. Once the battery voltage reaches 8.3V, the charging stops and the battery floats until it discharges back to 7.2V.

U15 measures the battery voltage by an internal A/D converter which looks at the V-BAT at U28-pin1. This voltage is generated by comparing VBB with Vref. The reference for the A/D converter is called ADC-REF.


Power Monitor PIC Microcontroller

 See Also

U15, PIC16LC72 (PIC) is a microcontroller that is programmed to sense and handle the external power interruptions to the terminal, charge the battery properly, and measure and implement temperature-related functions. The functions and role of this controller is as follows:

♦	Brown-out timing, monitoring, and power state control.

The PIC allows the terminal to operate for one second off the backup battery when main power from the 12V main power supply is removed. Following one second of operation off the backup battery, an NMI is issued to the main CPU to allow software to transition the terminal into suspend state. If the main CPU does not suspend the terminal within three seconds following the issued NMI from the PIC, the PIC performs a hard reset. The one second interval in which the terminal is operating off the backup battery is eliminated if the backup battery is low. Instead, the NMI from PIC to main CPU will be issued immediately following loss of 12V external power.

♦	Terminal brown-out recovery auto turn-on.

The PIC toggles the on/off switch to turn the terminal back on when 12V external power is restored. Auto turn on is only performed if the terminal was placed in the suspend state due to main power loss. If the suspend was due to a user generated on/off key press, the PIC will not generate an "ON" command when 12V power is removed and re-applied.

♦	LCD temperature compensation.

The PIC modifies the LCD bias voltage based on ambient temperature using a PWM output.

♦	Controls the charge cycle of backup battery.

♦	Monitors backup battery voltage and provided notification when the backup battery is low.

Provides battery status information to the main CPU over a two wire serial interface.

♦	Acts as a system watchdog.

The PIC resets the entire system via the SNEPWRGD reset when either the system is running off the backup battery for too long or if the system shuts down into off instead of suspend state.

♦	Manages the NiCad backup battery.

Determines the backup battery level. Turns on a C/10 charger when the backup battery approaches 60% capacity. Turn off the charger with loss of AC power, when the voltage on the battery no longer continues to rise, if temperature goes out of range, or if maximum charge duration is exceeded. The PIC switches in a 75mA load when measuring the backup battery voltage in order to eliminate surface charge.

♦	Provides battery status information to the main CPU over a two wire serial interface.

♦	Controls the HEAT_ON and FAN_ON outputs based on temperature and power state.

Terminal is shut down if internal temperature goes beyond 65 Celsius.

♦	Sets the contrast voltage for the LCD based on temperature and EPROM contents using PWM output.

The PWM output goes through a low pass filtered to create a DC control voltage.


Keyboard Assembly
Keypad Assembly

 See Also

The keypad assembly is an AT-compatible keypad with the exception of the œ button used to turn the unit on and off.

The assembly switch is made by a vendor and consists of a keypad matrix and a processor. The œ button is separate from the rest of the matrix.


Display Assembly

 See Also

The display assembly is an off-the-shelf 320X240 pixel quarter panel LCD with a CFL backlight. The display will support up to 25 lines by 40 characters.


Radio Assembly

 See Also

The RF terminals have a Proxim RangeLAN2, 2.4 GHz frequency hopping, spread spectrum radio with a 1.6 Mbps data rate plugged to J5. In the future other radios will also be supported.


LED Assembly

 See Also

This is an flexible PCB with 7 LEDs that plug into the main PCB. The functions of the LEDs are defined and controlled by software. These functions are defined in the Trakker Antares user’s manual.


Speaker Assembly

 See Also

The speaker assembly consists of a speaker, two wires and a connector that plugs into the main PCB. The drive circuitry is defined with the other PCB functions. The part number of this assembly is 054170.


Ethernet Assembly

 See Also

Ethernet assembly consists of a PC-card Ethernet card which should plug into slot A in the main board and a cable which is accessible in the back of the unit. A clamp-on ferrite is placed on the cable to reduce the EMI noise.


Backlight Inverter Assembly

 See Also

This assembly inverts +12V to a high voltage AC signals to run the Cold Cathode Fluorescent Lamp (CCFL). When the +12V is applied to the terminal, this assembly produces a 1500V AC signal to ionize the tube and start conduction. Once the tube start conducting the output voltage drops to a lower value (around 400 V.) Do not handle this assembly with power on.


I/O PCB Assembly

 See Also

This is the assembly that is visible when the back plate is removed from the terminal. All the user interface connectors are on this assembly. There are two versions of this assembly: Standard and Enhanced.

All the control signals are generated on the main PCB. This PCB contains all the drive and interface connectors.

The Enhanced version will include all the functionality of this assembly, which are:

♦	Scanner interface connectors

♦	Connector for external power supply

♦	BOOT-LDR jumper

♦	Reset switch

♦	3 serial COM (communications) ports

♦	Backup battery temperature sensor

♦	Auto trigger jumper

♦	4 digital output relays

♦	4 optically isolated digital inputs

In the Standard version of the assembly, the first 6 options are present. However, there is only 1 serial COM port instead of 3.


Scanner Interface on I/O board assembly

 See Also

There are two connectors for the scanner interface. One is the 10-pin Stewart connector which is an Intermec standard for most laser scanners. There is also a 6-pin RJ-45 connector which is used for a badge scanner.

This Terminal is able to handle the competitive (Symbol) scanners. The competitive scanners require an different voltage level at LASENABLE output and the GOODRD and Beep are multiplexed (for more information refer to document 605879, “Product Specification for Existing Interface Specification”). The handling of a competitive scanner is accomplished using a programmable logic IC (GAL16V8, U1.) The logic programmed to U1 generated the correct levels by the level input by signal CG-GEN-CTRL1 which is set in system configuration.

J6 is the Intermec standard 10-pin input device connector. The resistors, capacitors, and zener diodes provide ESD protection. When the TRIGGER* is pulled low by the input device, an interrupt to the system CPU is generated in the ASICA (on the main PCB.) The CPU responds by pulling the LASAENABLE* low (which keeps the laser on.) U1 generates the FC-LASEN signal depending on CG-GEN-CTRL1’s level. For Intermec compatible scanners this would be a logic low.

The following points also apply:

♦	SOS is a signal from the laser that indicates the start of each scan.

♦	BEEP is an output to driver the beeper in the scanner (most scanners do not have and internal beeper any more.)

♦	GOODRD* is and output that drives the good read LED in the scanner.

♦	VIDEO is the bar code information that the scanner has just collected. This signal is wired OR’d between the two VIDEO signals from J5 and J6, so both scanners should not be used simultaneously.

♦	Power supply interfaces are:

+12VF is created by fusing +12V with a 0.75Amp resetable fuse

+5VF is created by fusing +5V with a 0.75Amp resetable fuse


External Power Supply

 See Also

The 12V, 1.7A power supply plugs to J3. The power line is protected from power glitches by two tranzorbes and a zener diode. A 2Amp removable fuse protects the terminal from internal shorts.


Back Up Battery Connector

 See Also

The backup battery assembly, which resides behind the I/O PCB, plugs into this board. There is no conditioning of this power line on this board. The backup battery is piped to the main board through J9.


BOOT-LDR Jumper

 See Also

The BOOT-LDR jumper provides a means to boot the system directly to the “Loader Waiting” screen without a need for a keypad.

The default location of the jumper shunt (pins 2 and 3 of J1 shorted) pulls the BOOT-LDR signal down. If the shunt is moved to pins 1 and 2, the signal becomes high. The system software checks the status of this bit during boot up. If it is high, then the system software runs the Loader program and waits for a program download.

This feature is provided for times when the system becomes configured with a wrong keypad.


Reset Switch

 See Also

Pressing SW1 pulls the FORCE-RESET line high which causes a SNEPWERGD, and SYSPWERGD.


Serial COM (communication) ports

 See Also

The serial signals for all three COM ports are generated in the UARTS in VG-230, ASICA, and ASICB. J4, J11, and J7 are the connectors for the COM ports. Each signal is protected by resistors, capacitors, and zener diodes from ESD. U8, U9 and U10 are the level translation ICs.


Battery Temperature Sensor

 See Also

R12 is a Thermister placed near the backup battery. The resistance of this thermister changes with temperature. The changes in the resistance is sensed by the Power-Mon PIC on the main PCB and reported to the system software.


Auto Trigger Jumper

 See Also

If a jumper shunt is placed J14, the optical input 4 can be used as an auto-trigger input. More information is available in the user’s manual.


Digital Output Relays

 See Also

Users have access to 4 relay outputs through J12. The user’s manual explains their pin out and how to use them.

♦	K1,2, 3, and 4 are driven by 4401 NPN transistors. The relays are powered from +12V and the control signals are from ASICB, which powers down when the unit is suspended. The relay status are not retained during a power down or unit suspense.

♦	Diodes D7-10 are the free wheeling diodes to prevent back EMF during the relay switch-off.

♦	Relay control signal are sent from the main CPU, serially. U4 converts the serial data to parallel format and U5 latches the data.


Optically Isolated Digital Inputs

 See Also

Digital Inputs are wired in the first 8 positions of J13. For more detail about how to wire them, refer to the user’s manual.

Each input goes through 4 rectifying diodes (bridge rectifier configuration) to make it possible to reverse the input polarity without damaging the input electronics.

The current to each input is limited by two transistors and sense resistors. For example, OPT1 input current flows Q9 and R6 (Q8 is off and R47 is providing base current to Q9 which is fully on). If the voltage across R6 goes higher than 0.7V, the transistor Q7 will turn on, causing the transistor to turn off (because the Q7 is stealing the base current.) Thus, the current through Q9 becomes limited.
