Communication Ports
The IP Gateway includes support for TCP/IP over 10 Mbits/sec Ethernet LANs for
communication with the SCADA, and three serial ports for MDLC over various links (radio,
dialup and dedicated lines, multidrop wireline, serial RS-232 or RS-485) for communication
with the MOSCAD RTUs.
The IP Gateway supports multiple logical channels running the TCP/IP protocol over
Ethernet, thus allowing multiple processes running on the SCADA computer, to
simultaneously access a number of functions in the IP Gateway.
The IP Gateway software supports four communication channels that can be configured to
support the following links:
Port 1 A - Ethernet - 8-pin RJ45 connector, twisted-pair (TP)
Port 1 B - Ethernet - 15-pin AUI connector
Port 1 C - RS-232
Port 2 A - RS-485
Port 2 B - RS-232
Port 3 - According to the plug-in board (see table below)
Port 4 - According to the plug-in board (see table below)
Ports 3 and 4 are available with one of the following options:
