Figure 4-68: RS-422 Cables
Motor to Motor
An RS-422 daisy chain cable is used to connect the downstream end of one motor to the
upstream end of the next motor in the path. This cable is a standard pin-to-pin straight through
cable with a 4-pin M8 socket on one end and a 4-pin M8 socket on the other end. One M8
socket plugs into the downstream communication port on the motor and the other M8 socket
plugs into the upstream communication port on the next motor.
