Connecting Remote Sensors
Plug-and-play remote temperature sensors may be attached to the RAC at any time via the RJ-
12 connectors on the unit. Each sensor has a unique serial number and is automatically
discovered and added to the web page. Up to four temperature sensors may be connected.
NOTE
The display order of the sensors on the web page is determined by the
internal serial number of each sensor. Friendly names for each sensor
can be customized on the Display page. The RAC will only recognize RT
(Temperature) sensors. The sensor uses Cat. 3 wire and RJ12
connectors. Wiring must be straight-through: reverse polarity will
temporarily disable all sensors until corrected. The sensors use a serial
communication protocol and are subject to network signaling constraints
dependent on shielding, environmental noise, and length of wire. Typical
installations allow runs of up to 600 feet of sensor wire.
