The addressable universal (RTS) interface can be used to communicate between home automation or other third party systems and all Somfy (RTS) motors and controls.  It is capable of individual or group control and can be operated via Infrared Remote (Part# 1810498), RS232 or RS485 serial communication. Once an input is activated, an (RTS) radio command is sent to the motorized window treatment. Up to 16 addressable channels are available.

Initial shade programming and limit setting must be completed prior to assigning URTSII control. Initial shade programming requires a Telis remote or Decoflex wall switch.To expand the range of the URTSII, purchase an RTS Repeater.

Ease of Use:
Unit is great for integrating any SOmfy RTS motor. Connected to my PC to control shades. Had a little trouble figuring out the RS-232 DB9 pinout but finally got it!
