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.
