Inputs and Outputs
Comm5 Communications Link
The controller provides a total of six terminals for connection to the Comm5
communication link. It is not necessary to observe polarity for Comm5 communication
links. The terminal descriptions follow:
• Two terminals for communication to the board (In Comm);
• Two terminals for communication from the board (daisy chain) (Out Comm);
• Two terminals for a connection from the zone sensor back to the controller or for the
Rove
r se
rvice tool (Tool Comm).

Data Sharing
Since the controller uses LonWorks
®
technology, the controller can send or receive data
(for example, setpoint, heat/cool mode, fan request, and space temperature) to and from
other controllers on the communication link, with or without a building automation
system.
Wink
For more information on the wink capability, refer to “Green Status LED” on page 80.
Rover Service Tool
An RJ-11 communication jack (present on some zone sensor modules) is the connection
point between the Rover service tool and the communication link. The jack must be wired
to the communication link at the controller. Accessing the communication jack with the
Rover service tool gains access to all controllers on the link.
The Rover
™ service tool can be used to change the controller configuration properties
and update the application by downloading new code for both the Neuron and the
mega32 processors.
