Connecting a display to a Network Interface Module
The target display can also communicate over a network using a Network Interface Module. The target
display connects to one of the comm ports using the same cable as a direct processor connection. The
Network Module is shown below.

Selecting the Square-D Device Number
The target display will access a network device according to the device address set on the Network
Interface Module. The Network Device number is determined by reading the thumbwheel value on the
front of the module and adding a 0 or 1 in front of the module number for Comm Port 0 or 1
respectively. As shown above, the device address for Comm Port 0 is 025 and the device address for
Comm Port 1 is 125.
Determining the Route Numbers.
The Square-D Processor must connect to a Network Interface module by connecting one of it's comm
ports to one of the comm ports on the Network Interface module. From the first Network Interface
Module, other Network Modules can be connected using a coaxial cable. The target display must know
the Network Device address numbers in order to get to the processor module. In the following drawing,
only one Network Interface Module is connected to the Processor. The target display is connected to
device address 025 and the Processor is connected to device address 125. Therefore, the route to take
to get from the target display to the Processor is from comm port 0 (device address 025) to comm port
1 (device address 125). You will need to know this information when you name target display
variables.
