Verify communication with the network by viewing a module status
report in WebCTRL.
Wire the ZN551's inputs and outputs as follows.

Output wiring
To size output wiring, consider the following:
•
Total loop distance from the power supply to the control module, and
then to the controlled device
NOTE Include the total distance of actual wire. For 2-conductor wires,
this is twice the cable length.
•
Acceptable voltage drop in the wire from the control module to the
controlled device
•
Resistance (Ohms) of the chosen wire gauge
•
Maximum current (Amps) the controlled device requires to operate

regardless of the DIP switch settings.
The appropriate baud rate. See the MSTP
