Chapter 3 – Configuration
The Ethernet Gateway needs to be properly
configured to communicate with your RS485
networks. Two items are critical to proper
performance of your Gateway: the Gateway’s
Ethernet address and the RS485 port
communication settings. The Gateway’s Ethernet
address should be set so that the host software will
know how to address messages to the Gateway. You
must configure the Ethernet Gateway with the
appropriate baud rate and communications settings
for each RS485 port to match attached RS485
network. After initial setup, you should only need to
make changes to the Gateway’s settings after adding
devices or making system changes.
Follow the instructions in Section 3-1 to perform the
initial configuration. After the network is
operational, you may make configuration changes
through the dumb terminal. These procedures are
described in the following sections.
In all cases, be sure to save any configuration
changes to the Gateway’s hard drive (option 12) for
safe retrieval in the event of a power loss.
3–1 Configuration Procedure
Configuration of the Gateway requires a dumb
terminal with RS232 port set to 19.2 Kbps, 8 data
bits, no parity, and 1 stop bit. The easiest way to do
this is to use a portable computer with an RS232
port, and run the Terminal accessory program from
Windows.
Use a null modem cable to attach the laptop to the
RS232 port of the Gateway, power up the laptop
and launch the Terminal program (located in the
Accessories program group in the Windows
program manager). Click on the Settings menu,
then choose Communications. Set your
communications options to look like figure 12.
When you have set your communications options,
close the options window and power up the Gateway
(the ON switch is located on the front panel).
When the Gateway finishes powering up, the
following message is transmitted to the terminal:
Figure 12. Terminal communications settings.
You are now ready to configure the Gateway, as
outlined below:
1. Type SET (must be typed in capital letters)
then press <ENTER> to bring up the
configuration menu. If you make an error
typing in this string, wait ten seconds and try
again.
2. The terminal displays the configuration
menu:
