The CMD-4EX-SA has the ability to communicate over a RS-485 serial communication interface with the motion core using an ASCII protocol.  This allows for a simple, half-duplex, bi-direction multi-drop network using a single twisted pair.


Below is the detailed schematic of the RS-485 communication line input.
