Appendix A. Cable Pinout AssignmentsThis appendix contains cable pinout information for the following ports located on the back of the Indy workstation:
serial port
parallel port
Ethernet 10-BASE T port
ISDN (Integrated Services Digital Network) port
Ethernet AUI (Access Unit Interface) port
keyboard port
mouse port
SCSI port (Small Computer System Interface) port
 | Note: The figures in this chapter show the connector pin assignments, not the cable pin assignments.
|
Table A-1 shows cable pinout assignments for the two serial ports.
