To wire the ZN551 for
communications
ZN551 Control Module • Rev. 3/17/2005
You can address the ZN551 before or after you wire the control module for
power.
1
If the ZN551 has been wired for power, pull the screw terminal connector
from the control module's power terminals labeled Gnd and 24 Vac. The
control module reads the address each time you apply power to it.
2
Using the rotary switches, set the control module's address to match the
Address in the control module's Device Properties dialog box in
SiteBuilder. Set the Tens (10's) switch to the tens digit of the address,
and set the Ones (1's) switch to the ones digit.
EXAMPLE If the control module's address is 35, point the arrow on the
Tens (10's) switch to 3 and the arrow on the Ones (1's) switch to 5.
10's
1's
The ZN551 communicates using BACnet on the following types of network
segments:
•
ARC156 communicating at 156 kbps
•
MS/TP communicating at 9600 bps, 19.2 kbps, 38.4 kbps, or 76.8 kbps
NOTE ARC156 is a unique implementation of the industry standard
ARCNET. For a summary of differences between ARCNET and ARC156, see
the ARC156 Wiring Technical Instructions (http://info.automatedlogic.com).
