Connecting a Controller to
an RS-485 Network
If you are not connecting the controller to an RS-
485 network, skip this section.
485 network, skip this section.
You can network controllers two different ways.
The first way is to use the SyncLink port and the
Network port to daisy-chain the controllers. This
method is shown Figure 11. This method is only
possible, however, if the SyncLink port is not used
for the SyncLink feature.

If the SyncLink port is already in use (or will be in
use), you can network the controllers by
connecting an RJ-12 “T” adapter to the Network
port, as shown in Figure 12.

You can connect a maximum of 32 controllers in an
RS-485 network. More than 32 controllers requires
multiple networks.

Figure 13. SyncLink and Network connectors
Table 7 and Table 8 show the pinouts for the
SyncLink and Network ports. To connect the
controllers in an RS485 network, you must connect
pin 1 of either the SyncLink port (method 1) or the
Network port (method 2) on one controller to pin 1
of the Network port on the next controller. Similarly,
pin 4 must connect to pin 4 and pin 5 to pin 5.
