NOTE Use the same baud rate for all control modules on the network

segment.

Insert the power screw terminal connector into the ZN551's power

terminals.

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

Set DIP switches 1 and 2 to...

N/A. Baud rate will be 156 kbps

regardless of the DIP switch settings.

The appropriate baud rate. See the MSTP

Baud diagram on the control module.
