Installation
For the location of the transmitter module, select a place which is not shielded by conducting objects and position the antenna in such a
way that it is not subject to interference from the rest of the circuit and is parallel to the transmitter antenna.
Pay attention to the correct polarity when performing the connections and make sure the technical data are kept
within specifications. If the voltage supply exceeds the specified voltage, the electronic components may be
destroyed, for example, when using unregulated voltage sources. Since the circuit is unprotected, it is necessary to
avoid static discharges and mechanic influences.
Transmitting
In order to realise a first test of functionality it is sufficient to connect one of the 4 digital inputs (4, 5, 8 or 9) to GND (11). All other inputs
may remain open and are not necessary for function.
Learning the transmitters code
Please take into account that the receiver has to learn first the transmitters address (please refer to the receivers manual).
Wiring
Please find enclosed a wiring example for the usage of different functions.

Flashes for each data package transmitted (even without acknowledgement)
Flashes twice for each data package transmitted to show local battery problem
Frequency 1 (433.62 MHz)
Frequency 2 (434.22 MHz)
If the supply voltage drops below a critic level the CX-12 T shuts down and a specific melody sounds
1 beep sounds for the reception of an acknowledgment if the receiver output state has changed. If no
acknowledgement is required, than 1 beep sounds if the transmitter input state has changed.
A specific melody sounds if acknowledgment is required but not received within approx. 2s.
Flashes 3x if receiver supply voltage is low
Flashes 8x if receiver supply voltage is critical
e.g. for an antenna (173mm wire) or 50Ohm-coaxial cable.
. This causes an augmented current consumption.
