Notes:
1. RS-232C and RS-422 are mutually-exclusive features.
2. Always use a shielded multicore cable up to a maximum of 15m (49.21ft) in a low noise environment. However, if the RS-232C communication is set up with a baud rate of more than
38400bps, keep the cable length to within 3m (9.84ft).
3. In the final axis, connect between TRE and RDN.
4. Use the maintenance relay card (MR-J2CN3TM) when connecting the analog monitor output 1 (MO1), analog monitor output 2 (MO2) and a personal computer.
5. Connect the shield wire securely to the plate inside the connector (ground plate).
