4.1.2 Communication Ports
The following three interfaces are provided as communication ports:
RS232C port
RS485 port
IRIG-B port
RS232C port
This connector is a standard 9-way D-type connector (straight type) for serial port RS232C
transmission and is mounted on the front panel. By connecting a personal computer to this
connector, setting and display functions can be performed from the personal computer.
RS485 port
One or two serial communication ports can be provided. In the single-port type, it is connected
to
the RSM (Relay Setting and Monitoring system) via the protocol converter G1PR2 or
IEC60870-5-103 communication via BCU/RTU (Bay Control Unit / Remote Terminal Unit) or
Modbus to connect between relays and to construct a network communication system. (See
Figure 4.4.1 in Section 4.4.)
In the case of the double-port type, one port (COM1) can be used for the relay setting and
monitoring (RSM) system or IEC60870-5-103 or Modbus communication, while the other port
(COM2) is used for IEC60870-5-103 communication only.
Screw terminal for RS485 is provided on the back of the relay as shown in Figure 4.1.1.
The setting of protocol used can be set by setting menu “PRTCL1” as shown in the table below.

IRIG-B port
The IRIG-B port is mounted on the transformer module, and collects serial IRIG-B format data
from the external clock to synchronize the relay calendar clock. The IRIG-B port is isolated from
the external circuit by a photo-coupler. A BNC connector is used as the input connector.
This port is on the back of the relay, as shown in Figure 4.1.1.
