ASP Portable Barcode Reader
PCs with Non-standard Keyboards
Certain PCs are not compatible with the IBM "standard" at the keyboard level,
which means that the ASP Portable BCR cannot normally be used with them.
Certain network software also modifies the keyboard signals in the server
machine sufficiently to make it incompatible with the Portable BCR. To
overcome these problems, ASP has written a software driver called ASPKey,
which "connects" an RS-232 port to the keyboard buffer in software, allowing
the Portable BCR to be connected to a problem computer via an RS-232 port.
Full documentation of the ASPKey driver is provided when you purchase
ASPKey, but cable details are provided below for completeness.

Display Contrast Adjustment
The LCD display on the Portable BCR is factory adjusted for optimal contrast
in a variety of conditions. In the unlikely event that further adjustment is
required, the contrast control can be accessed by opening the Portable BCR's
case, and adjusting the contrast control, which is located between the display
mounting posts at the right side rear of the circuit board.
