Room Sensor Transceiver (RSX)
A Room Sensor Transceiver (RSX) connects to the RTS port of a TEC device. The RSX enables the TEC
device to wirelessly communicate with a Wireless Room Sensor (WRS). Each RSX supports one TEC and
one WRS, and each WRS supports one RSX and one TEC.
Figure 2. Room Sensor Transceiver (RSX).
The RSX provides an indicator light to furnish operation and communication link status. See Table 1 to
monitor current RSX status.
In Table 1, rapid
