Understanding Feedback 
and I/O Cable Connections
The procedure in this section assumes that your 1394 system and axis 
modules are already mounted and your power is wired. In this section 
you will:
• Prepare the feedback and I/O cables for wiring to connector 
housings.
• Make the connections and plug the housings into mating 
connectors on the bottom of the 1394 system module.
• Attach the feedback cable clamp to the feedback cable shield.
