Figure 14: Rear serial port terminals

An additional serial port with D-type presentation is available as an optional board, if required.
The power supply board also provides a rear serial port. The rear serial port (RP1) is an EIA(RS)485
interface, which provides SCADA communication. The interface supports half-duplex communication and
provides optical isolation for the serial data being transmitted and received.
