Networking
RS485 Networking
The RS485 network port is located on the right
side of the Ethernet Gateway board. This port is
where you must connect your RS485 devices.
Using shielded three-conductor network cable
(Belden #8641 or equivalent), connect the
RS485 I/O Network wire to the three-terminal
connector on the Ethernet Gateway Board as
shown in
Figure 3
. For further information
about how RS485 networks are configured,
refer to your site controller’s user manual.
The RS485 network termination jumpers are
located next to the RS485 network port. If the Ethernet Network Gateway board is at either end of
the RS485 daisy-chain, set the termination jumpers to the UP (terminated) position. Otherwise, if
the board is not at the end of the network daisy-chain, set the termination jumpers to the DOWN
(unterminated) position.
Ethernet Networking
The Ethernet port is located on the lower left
side of the Ethernet Gateway Board (see
Figure
4
). The port accepts a standard CAT5 cable with
RJ45 connector. Insert the RJ45 connector tab-
side down into the port until it clicks. Connect
the other end of the cable to the network hub or
switch.
Like all TCP/IP devices, the Ethernet Gateway
Board requires an IP address, Gateway IP
address, and other network information. These
values are configured through the Hand-Held
Terminal (HHT) interface.
RS232 Networking
The RS232 port is located on the upper left side
of the Ethernet Gateway Board (see
Figure 5
).
Use any standard serial cable with a 9-pin
female connector. Plug the connector into the
RS232 port and secure the connection using the
screws on the cable connector.
RS232 baud rate settings are configured
through the Hand-Held Terminal (HHT) inter-
face.
