13. COMMUNICATION FUNCTIONS

13. COMMUNICATION FUNCTIONS
The MR-J2-03A5 has the RS-422 and RS-232C serial communication functions. These functions can be
used to perform servo operation, parameter changing, monitor function, etc.
However, the RS-422 and RS-232C communication functions cannot be used together. Select between RS-
422 and RS-232C with parameter No.16. (Refer to Section 5.2.5.)
This function is also available for RS-485. Make the same connections, settings, etc. as in RS-422.
