Cable Connector Descriptions
This appendix describes the connector pinout for the cables that connect
to your 7344/7334 boards.
Figures B-1 and B-2 show the pin assignments for the stepper and servo
50-pin motion connectors. These connectors are available when you use
the SH68-C68-S shielded cable assembly and the 68M-50F step/servo
bulkhead cable adapter.
