The TM13 transceiver module is required to interface
X10 wireless RF transmitters with the power lines.
It receives Radio Frequency (RF) commands sent from
any X10 RF transmitters and then converts them into X10
commands for transmission on the power lines to X10 modules.
Each TM13 controls works on only one house code,
giving you control of up to 16 modules (or groups of
similarly addressed modules) operating on the same house
code.
The TM13 is not limited to work with only one RF
transmitter, it can be used with as many remote controls or
motion sensors as you want, providing they are all operating
on the same house code.
Includes a built-in Appliance Module (fixed to Unit
Code 1), for added functionality.
