Wiring for RS485

The Motion Coordinator has a 4-wire RS422 port.  This can be set as a 2-wire RS485 port by wiring the Tx and Rx together.

MC664 is shown.  All Motion Coordinators have the same port pin configuration.

For some protocols it will be necessary to set up the software for 2-wire operation.  See SETCOM and MODBUS commands.
