Section 1: Introduction
This note describes the connection of the RUGGEDCOM RMC30 external Ethernet interface to the
RS485 port of Reyrolle Relays.
The new generation of Reyrolle relays support the DNP3 communications standard, in addition to
MODBUS and IEC60870-5-103 provided previously. Each communications port allows the user to
select a protocol, independent of the other ports, via a setting accessed through the Relay’s fascia. In
a communications system the Relay will be the slave device. There is a requirement for Ethernet
access to these relays and the RMC30 device provides a solution to accomplish this requirement.
The RMC30 can be configured as a dedicated MODBUS server, DNP3 SERVER, or a simple Ethernet
tunnel. Examples of all three methods are described below.
The information for the RMC30 was taken from [1] Rugged Operating System v3.2 User Guide, please
refer to that document for a more detailed description of configuration.

Section 2: Physical Connection
2.1 RELAY COMMUNICATION PORTS
2.1.1 RS485 Interface
The RS485 communication port (COM1) is located on the rear of the relay and can be connected
using a suitable RS485 120 ohm screened twisted pair cable. On the RM platform it uses terminals
14(A), 16(SCREEN), 18(B) and 20(TERM) of the PSU terminal block.
The RS485 electrical connection can be used in a single or multi-drop configuration. The RS485
master must support and use the Auto Device Enable (ADE) feature. The last device in the connection
must be terminated correctly in accordance with the master device driving the connection. The relays
are fitted with an internal terminating resistor which can be connected between A and B by fitting an
external wire loop between terminals B and TERM on the power supply module. A full diagram of the
rear terminal blocks is shown in the Appendix, Figure 29 – Rear Terminals for E8 case (5CT/4VT).
The maximum number of relays that can be connected to the bus is 64.
Access to the communication settings is only available from the relay front fascia via the
COMMUNICATIONS MENU. The following settings must be configured via the relay fascia when
using the RS485 interface.
Setting name Range Default Setting Notes
Station Address 0 … 254 0 1-254
An address between 1 and 254
must be given to identify the
relay. Each relay must have a
unique address.
COM1-RS485 Protocol OFF, IEC60870-5-103,
MODBUS-RTU, DNP3
IEC60870-5-
103 As Required
Sets the protocol used to
communicate on the RS485
connection.
COM1-RS485 Baud Rate 75 110 150 300 600 1200
2400 4800 9600 19200
38400
19200 As Required
The baud rate set on all of the
relays connected to the same
RS485 bus must be the same
as the one set on the master
device.
COM1-RS485 Parity NONE, ODD, EVEN EVEN As Required
The parity set on all of the
relays connected to the same
RS485 bus must be the same
and in accordance with the
master device.

2.2.1 RS485 Interface
Connect the Serial Port terminals to the Relay. For an RS485 2 wire connection connect the –Rx
terminal of the Phoenix connector to A on the Relay, and the +Rx terminal to B.

2.2.2 RS232 Interface
If required you can connect the RS232 port of the RMC30 to a PC, for example, if you cannot
configure the device via the Ethernet connection, as shown below.
Figure 3 – RMC30 RS232 connection
2.2.3 Ethernet Interface
Connect the RMS30 to the network using a standard RJ45 Ethernet cable.

Section 3: Configuration of RMC30 Device
3.1 CONFIGURE RMC30 IP ADDRESS
You can change all the parameters via a Web Browser; however, to do this you must use the IP
address of the RMC30 device. If the default address (192.168.0.1) is not suitable for your network you
must change it using a Terminal program, e.g. HyperTerminal or TeraTerm. To do this you should
connect the RS232 port of the RMC30 to a PC.
Power down the RMS30 and then temporarily disconnect the Ethernet cable and RS485 connection.
Start a terminal program connected to the PC serial port with parameters Baud Rate 57600, No Parity,
8 bit data and VT100 emulation. While holding down CTRL+Z on the PC keyboard power up the
RMC30. After a short while you will be presented with a screen as follows.
