When an internal modem is installed, the relay’s Port 2 is used to interface to
the modem internally. Appropriate Port 2 settings are configured at the factory
when the internal modem is installed. The factory defaults are: “M0S0=0&B1”
for an external modem and “M0S0=0” for an internal modem.
Network Link
Figure 2.4: Network Link
You can access both the relay’s user interface and DNP3 SCADA services si-
multaneously through the same network port with an optional Ethernet TCP/IP
LAN link. If the Ethernet option has been installed, Port 5 on the rear panel will
be labelled “NETWORK.”
The user interface accessed through the LAN is the same as that available
through a direct serial connection or a modem link, but requires the use of a
Telnet client on your PC. The HyperTerminal program included with Mi-
crosoft Windows provides Telnet services. To select Telnet, go to HyperTer-
minal’s Properties dialog box and set the
Connect Using field to TCP/IP
(Winsock) . If this option is not available in the pick list, you require a newer
version of HyperTerminal (v1.2 or greater). Alternatively, you can use any
Telnet program that fully supports VT-100 terminal emulation and z-modem
file transfer.
DNP3 SCADA services can also be accessed over the LAN, for details see
“Accessing the SCADA Services” on page 2-7.
Connect Port 5 to the Ethernet LAN using an appropriate 10BaseT cable with
an RJ-45 connector. The relay supports 10 Mbit Ethernet, although a dual
speed 10/100 Ethernet hub or switch can be used.
By default, the relay is assigned an IP address of 192.168.1.100. If this address
is not suitable, it may be modified using the relay’s Maintenance Menu. For
details see “Using HyperTerminal to Access the Relay’s User Interface” on
page 2-5.
