3.7 Printer Interface

The printer interface on the Storage/Control I/O Module front panel supports parallel system

printers through a 36-pin Centronics-type connector. Figure 7 shows the cable wiring diagrams

for connecting the Storage/Control I/O Module parallel port to the system printer.

NOTE: The End of Line (EOL) terminator for the system printer must be defined in

the system data base via the Peripheral Configuration screen prior to use (refer to

the Cisco VCO/4K System Administrator's Guide for more information).

Figure 7: I/O Module To System Printer – Cable Wiring Diagram

NOTE: You can employ a 36-conductor, straight-thru parallel cable to connect a

printer to the system controller; however, only the conductors shown above are used.

For more information on the parallel 36-pin Centronics cable available from Cisco

Systems, refer to the Cisco VCO/4K Hardware Planning Guide.

The SCSI mass storage bus interface on the Storage/Control I/O Module is not used in system

operation.
