Version “17” Pin Assignments for Keyboard Wedge, RS-232 and
Light Pen Emulation
The version “17” scanner head cable is terminated with a male 25-pin D-type
connector. To connect the scanner to the PC, may require a communication
cable and a transformer. The communication cable is terminated to two 5-pin
DIN connectors that will directly connect to an IBM PC XT or AT compatible
computer and keyboard. For the scanner to connect to an IBM PS/2 computer
and keyboard, an adaptor kit with 6-pin mini-DIN connectors is provided
when requested.
The version “17” scanner is designed to be used as a keyboard wedge.
However, with the appropriate communication cable, the scanner will also
provide RS-232 or light pen emulation interface. When configuring the
scanner for one interface versus another, change all necessary parameters for
that particular interface. For instance, to configure the scanner for keyboard
wedge emulation, recall defaults, select the PC type, keyboard country type
and intercharacter delay. For further information, refer to the ScanSelect™
Scanner Programming Guide or ScanSet™ Scanner Configuration Guide.
The following is a list of the pin assignments. The pin numbers are impressed
on the head cable’s connector.
