D20E ETHERNET I/O MODULE INSTRUCTION MANUAL
The D20E modules network communication uses two redundant switched 10/100Base-T
interfaces, with RJ45 connections for category 5 UTP cable. This is implemented with either
of the following protocols:
•
DNP3 TCP/IP or
•
IEC 61850 GGIO.
There are two switched LAN Ports on the D20E modules:
•
LAN 1 and
•
LAN 2.
Each LAN port has a dual switched physical connection, where two RJ45 connectors for
LAN 1 share the same MAC and IP address and two RJ45 connectors for LAN 2 sharing
another one.
The Ethernet ports can also be used to configure a D20E module when connected to a
Windows PC computer running the DAPserver Studio.
The D20E modules have two predefined default IP addresses:
•
LAN 1 = 192.168.0.189 on eth0 and
•
LAN 2 = 192.168.1.189 on eth1.
You can change the default IP addresses to new IP addresses to match your network IP
address assignments.
Typically, you can modify an IP address from DAPserver Studio
In the unlikely event that you are unable to access the D20E Ethernet I/O Module from
DAPserver Studio, it may be necessary to modify an IP address using Linux.
