Please select according table 1 which of the 4 bits T1-T4 shall be transmitted. T1 to T4 correspond also to the 4 push buttons of a hand held
transmitter of the series SH-12. This allows to control for example the same receiver in parallel by TX-121 and another transmitter.
Furthermore you may select between key- or state transmission. Key transmission will transmit the signal as long as the external contact is closed
whereas the state transmission will transmit the signal for about 2 s at any time the contact changes its state (ref. table 1)
All devices of the series SH-12 may use one of 2 selectable frequencies. Factory pre-setting is always frequency 1 (f1). Yoy may select the
second frequency f2 at any time. In this case please note, that the corresponding receiver has to be set also to f2.

4 Installation
Connect the supply voltage to the input (4,5 … 16 V).
Attention: Take care of the technical data and of the supply polarity.
All transmitters, such as TX-121 have to be teached to the corresponding receiver. For further details please refer to the receivers manual.
Transmission may be initiated by shortening the both screws (ext. contact). Please keep a distance of about 1m between transmitter and receiver.
LED1 flashes 3 times per second while TX-121 is transmitting and is receiving the acknowledgement of the receiver. In case that TX-121 do not
receive the acknowledgement the LED 1 flashes quickly for about 2s as an indicator that connection is searched. After this time without any
correct answer the transmission is stopped.
LED 2 flashes after each Start and Stop of transmission to indicate the receivers confirmation. When using CX-12 R this function depends on the
wiring of the receiver module and may be different.
