5.2. Communication
5.2.1. Overview
EVRC2A has four ports for communication.
The EVRC2A has the front panel RS232 port, the side panel RS232 port, the side panel RS485
port(or RS232 port) and the side panel Ethernet port.
Communication port settings are available as follows in “Table 5-1. Communication Ports
setting of EVRC2A”.

Port Type Speed Parity bit Data bit Stop bit Location
PORT1 RS-232 57600 bps No parity 8 1 User Interface Front Panel
PORT2 RS-232 1200 - 19200 bps No parity 8 1 User Interface Side Panel
PORT3
RS-485
or RS-232
1200 - 19200 bps No parity 8 1 User Interface Side Panel
PORT4 RJ45 10BASE-T/100BASE-T User Interface Side Panel
PORT1(RS232)
A port to interface with Interface Software.
PORT2(RS232) – Option
The Port2 is a port for a serial communication for MODBUS, DNP3.0 or IEC60870-5-101
protocol. A user can select the protocol and configure the Port2 for the selected protocol by
changing baud rate and/or other settings for the Port2.
PORT3(RS485 or RS232) – Option
The Port3 is a port for a serial communication for MODBUS, DNP3.0 or IEC60870-5-101
protocol. A user can select the protocol and configure the Port3 for the selected protocol by
changing baud rate and/or other settings for the Port3.
The Port3 type of EVRC2A-N is a fixed RS485 port. However, the Port3 type of EVRC2A can
be selected as RS485 or RS232 by a user. In order to use RS485 port for EVRC2A, the Pin4 and
Pin5 of RS485 should be connected.
