UNIVERSAL RTS INTERFACE II
Operating Instructions
The addressable Universal RTS Interface II (URTSI II) can be used to communicate
between home automation or other third party systems and SOMFY’s RTS Motors and
controls. It is capable of individual or group control, and can be operated via infrared
remote, RS232 and RS485 serial communication. Once an input is activated, an RTS
radio command is sent to the automated window treatment.

* As an option, power to the URTSI II can be
supplied on leads 4 & 5. In this case, the
plug-in transformer is not needed. In addition,
the power can be daisy-chained to the next
URTSI II over the CAT5 cable. The power
supply should be sized based on the number
of Interfaces on the network segment.
NOTE: Do Not remove antenna.
If a new antenna is needed, it
must be ordered from Somfy to
ensure FCC requirements are
maintained.
