3.1 Configuring and testing the keyboard
The ATB420/421 has options which are stored electronically and which may be altered using a
simple utility from Access Keyboards (ATBconfig.exe). This program runs under Windows.
The ATBconfig.exe may be run with the ATB420/421 connected on any Windows system to set up
the required ATB420/421 configuration. Once saved the ATB420/421 keyboard saves its settings
and can then be disconnected and installed on another computer with these settings.
When run, ATBconfig.exe will scan the computers available RS232 ports and locate the
ATB420/421 keyboard.
Please find below the instructions for using ATBconfig.exe: Atbconfig.exe
This utility allows users to configure and test the ATB keyboard and may be download from Access
Keyboards web link i.e. www.accesskeyboards.com/downloads/atbutils.
1. Connect the keyboard to a PC running Windows 98, XP, 2000 or NT, by connecting the PS2
connector to the keyboard port and the serial connector to any available serial port.
2. Run the utility ATBconfig.exe. The program will automatically locate the serial port the keyboard
is attached to and adjust to its current communication settings. Should this fail for any reason, e.g.
port not free, connect to an alternative port and click on 'Locate Keyboard'.

ACCESS KEYBOARDS
ProgBox Rev 2.0X
After a few seconds it will display what keyboard code is currently loaded in the ProgBox e.g.
ProgBox Config:
OCR 28XKYD 3X
Press the SCROLL button once to display
ak105d1c-003X.hex
Complete Load
Press the START button once.
The ProgBox will download all of the necessary files to the keyboard. This will take about 3
minutes per keyboard.
Status messages will be displayed during the download to show the progress of the operation.
When the programming of the keyboard is complete the ProgBox will display
* Download OK *
This will be displayed until a button is pressed or power is removed.
The keyboard must be powered down by switching off the PC or removing the power adaptor
before use or calibration.
Download Failures
If the keyboard fails to re-program correctly the ProgBox will display
DOWNLOAD FAIL
This message will stay on the display until the box is powered down. If a download failure occurs
remove power from the keyboard and ProgBox then re-apply power and start again.
Calibration of the OCR Engine
Once the correct OCR firmware has been loaded the OCR Engine needs re-calibration. This can
be done in two ways and is dependant on the level of the OCR firmware that was previously loaded
in the engine. In most cases and certainly for OCR firmware levels from 0025A onwards an Access
OCR Service Card through the keyboard slot can be used.
With your normal application running check that the 9 way D connector of the keyboard is correctly
connected and the red LED is off. Take the cream coloured OCR Service card and swipe it slowly
(approx 1-2 inches/sec), in the direction of the arrow, through the OCR slot, making sure that the
card is kept flush against the metal guide plate throughout the swipe. After a delay of a few
seconds the light on the keyboard should turn green and five beeps should be heard. 4
If the light turns red and seven beeps are heard, check the slot is clear of debris and that the glass
window in the slot is clean, if necessary use a cleaning card (CARDCLEAN05) to remove any dirt.
Repeat the swipe with the service card to get the green light and five beeps.

4. OCR swipe technique
The OCR reader operates with a broad range of swipe speeds. To maintain data integrity, very
fast swipe speeds are ignored completely and swipe speeds slightly exceeding the maximum
allowed by the ATB420 will result in a bad read message of 30 “*” characters, a Red light indication
from the Bi-Colour LED and 3 beeps from the sounder.
A label is attached to the slot area to assist operators/agents to the swipe direction and position of
passports and other travel documents
Operators should follow the following procedure.
Insert the document at the right hand end of
the slot, orientated with the OCR data to be
read facing the operator.
Swipe from right to left.
Continue swipe, at a steady speed, along the
slot.
Ensure swipe action continues to the end of
the slot before lifting the document.

5. Data Format Protocol
The ATB420/421 has efficient RISC based micro-controller electronics allowing configurations to
be changed and down-loaded in the field. Access Keyboards can provide data format protocols to
user specification upon request.
5.1 Keyboard Data
All keyboard data is handled in accordance with industry standard Windows 104/105 keyboard data
protocol, command structure and code tables and the keyboard element communicates via the 6
pin mini-din interface. For further information refer to IBM Technical Reference Guide (Available on
request).
5.2 Host Port RS232C Settings
Data from the integrated MSR, Bar Code Port and Auxiliary RS232 port of the ATB420/ATB421 is
transmitted via the RS232 Host Interface in serial asynchronous format adhering to RS232C/V24
specifications.
Default Com Port Settings are 9600 baud
7 Bit
Even Parity
One stop Bit.
The ATBconfig.exe described in Section 3.1 allows selection of 19200 Baud. 8 Bit, No Parity is
also available.
5.3 RS232 Data Format
In the following descriptions hexadecimal values are represented by a four digit string in the form
0xxH where xx are values between 00 and FF. e.g. ASCII character A = 041H.
ASCII control characters are shown as the ASCII mnemonic enclosed with < >.
e.g. <STX> = 002H
The ASCII characters < > are always shown in their Hexadecimal equivalents if actually part of the
transmitted data.
Excluding keyboard data, data to and from the ATB420/421 is transmitted in the form of blocks.
An ASCII table is included as Appendix A
The following control characters are used to control and identify the flow of data across the RS232
