Connector
Description
COM A
Communication port A, or the RJ-45 port. Used for the setting tool connection and for IEC 61850, Modbus/
TCP, IEC 104, DNP3 and station bus communications.
COM B
Communication port B, or the RS-485 port. Used for the SCADA communications for the following protocols:
Modbus/RTU, Modbus I/O, SPA, DNP3, IEC 101 and IEC 103. The pins have the following designations: Pin 1 =
DATA +, Pin 2 = DATA –, Pin 3 = GND, Pins 4 & 5 = Terminator resistor enabled by shorting.
