Set Communications
Selection jumper to... Set DIP switches 1 and 2 to...
ARC156 ARC156 N/A. Baud rate will be 156 kbps
regardless of the DIP switch settings.
MS/TP MSTP The appropriate baud rate. See the MSTP
Baud diagram on the control module.
NOTE Use the same baud rate for all control modules on the network
segment.
5 Insert the power screw terminal connector into the ZN551's power
terminals.
6 Verify communication with the network by viewing a module status
report in WebCTRL.
Wiring inputs and outputs

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
