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. Connecting the scanner to a PC, requires a communication cable and a transformer. Connecting the communication cable to a PC, may require an adaptor cable. This can be ordered when the scanner is purchased.

The version “17” scanner is designed to be used as a keyboard wedge. However, with the appropriate communication cable, the scanner will also provide an 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, when configuring 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.
