Wiring Point-to-Point The RS422 port on the operator terminal is connected to the PU port on the FR-A/F/E/D frequency inverter system or to the RJ45 port on the FR-S500 inverter system with the standard cable CAB9.

The RS232 port on the operator terminal is connected to the PU port on the FR-A/F/E/D frequency inverter system or to the RJ45 port on the FR-S500 inverter system with the standard cable SC-FR-PC.
