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.
