4.1.2 Communication
Ports
The following interfaces are provided as communication ports:
•
RS232C
port
•
RS485 port or optional fibre optic
•
IRIG-B port (provided for model 4
∗∗
series only)
•
Interface port for telecommunication system
RS232C port
This connector is a standard 9-way D-type connector 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) 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 two-port type, one port can be used for the relay setting and monitoring (RSM)
system or IEC60870-5-103 communication, while the other port is used for IEC60870-5-103
communication only.
Screw terminals for RS485 or ST connectors for fibre optic interface (option) are provided on the
back of the relay.
IRIG-B port
The IRIG-B port 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.
This port is on the back of the relay, as shown in Figure 4.1.2.1.
Interface port for telecommunication system
The pilot wire and/or fibre optic port for telecommunication system is provided on the back of
the relay as shown in Figure 4.1.2.1. In the case of fibre optic port, LC connector is provided.
