Remote switch system FTS14
Operating mode RT (direction pushbutton)
The RT mode is preferred for Venetian blind control and saves a lot of time for teach-in since only a couple of commands need to
be taught in. In RT mode, the FTS14EM generates 5 even-numbered IDs per terminal pair and their ID range is dependent on a
combination of the two rotary switch positions. In addition, the signal generated also contains a code for the rocker half or rocker
end derived from the wireless pushbutton. This must be considered when programming manually with PCT14. When RT mode is
used, the pair formation (E1/E2) and switch function assignment (E1=up; E2=down) must be considered. In case mixed RT and
UT commands are required on an input module, select the UT group. In this case, the two input commands must be taught in
separately for direction pushbutton functions.

Structure of ID HEX code
To considerably speed up derivation of the hex code ID for input into the PCT14 from the terminal description and rotary switch
setting, they are generated in "quasi-decimal" notation.
Here is an example:
The ID codes generated in the FTS14EM always consist of the basic hex code 00 00 1x xx.
x xx
is dependent on the two rotary switch settings (group below, decade above) and terminal:
x
-- rotary switch below: Group e.g.
1
0 1
-
x
- Upper rotary switch: Decade e.g.
2
0
- -
x
Input terminal:
e.g.
E
5
This results in the ID:
00001 125
