Operation Instructions GB
1 Mode of Operation
The transmitter module CX-12 T sends serial data to the corresponding receiver, e.g. switching signals (ON/OFF states), and transmits
also measurement values in digital form. The acknowledgement from the receiver will be handled according the following description.
It is forbidden to modify or change component parts of the product ! The electronic components are not protected against weather
conditions. Therefore, it should not be used in the exterior without taking necessary precautions. The cable connections should not be
longer than 1 m.
It should be noted that for applications that could put human life at risk, by using radio connection there is
always present a potential hazard due to extraneous disturbances.
The Operating Instructions need to be followed at all times.
2 Range of operation
The system is designed for large operating range up to 1000 meters and even obstructing walls or steel reinforced constructions can be
penetrated.
The range may be reduced for the following reasons:
• Buildings, vegetation or any other objects will substantially reduce the operating range.
• The distance between the antenna and the human body or other conducting objects (e.g. Earth) may influence the working range.
• "Background electrical noise" could be relatively high so that the signal-to-noise-ratio decreases and therewith the range.
Also other devices, with similar operating frequency, located within the neighbourhood may disturb the receiver.
• Operating the receiver next to inadequately shielded electronic boards or other devices (e.g. PC’s) that produce electromagnetic
radiation, can substantially reduce the range of operation and could result in an apparent intermittent operation.
• It is forbidden to modify, change or manipulate component parts of the product!
3 Description
CX12 T transmits the information of 4 digital inputs together with a factory programmed address to a receiver of the series SH12. The
transmission will be initialised by activating of at least one digital input. Furthermore CX12 T transmits an analogue value supplied at pin
1 and an information of the local power supply. In case of well established radio communication the module gets the acknowledgement
of the receiver in combination with its RSSI-signal as well as an information of the receivers supply voltage. To show functionality there
are 2 LED outputs and 1 output which controls a piezo transducer (disk without electronics)
CX12 T has an individual factory programmed address (4 Byte).
So the corresponding receiver has to learn this unique address.
On request it is possible to program more than
one CX-12 T with identical addresses.
In order to obtain a maximum of safety you may change
over to a second working frequency if the first frequency
channel is disturbed by another radio service.
Pin Description:
1 Input for an analogue voltage between GND and +U to be transmitted. The value will be sent at the same time an
input is activated.
2 Output to keep the supply voltage of the transmitter module until all initialised functions are realised (high active)
May be used in circuits where e.g. the supply is completely switched off by a transistor.
3 Output to control a LED (low active)
Transmitting data: flashes for each data package transmitted (even without acknowledgement)
Low Battery: flashes slowly to show local battery problem
4 Input 4: Digital input with internal PullUp resistance (low active)
5 Input 3: same as input 4 (Pin4)
6 Analogue Output of the feeded back received signal strenght (RSSI) that the receiver detected (value between +U and GND,
Ri=56 kOhm)
7 F2_SEL Input to fix the working frequency
open or +U: Frequency 1 (433.62 MHz)
GND: Frequency 2 (434.22 MHz)
8 Input 2: same as input 4 (Pin4)
9 Input 1: same as input 4 (Pin4)

10 +U : Tension d’alimentation positive entre 2,0 et 3,6 V DC
11 GND: Masse, 0V DC
12 n/c : ne pas connecter
13 Sortie Sortie de commande d’un transducteur céramique piézo (sans électronique) (high activ)
Acquittement immédiat, 1 bip à l`allumage et un bip à l’arrêt
Sans acquittement et après 2sec d´essai d’émission 3 x bip pour mise en marche et 2sec.plus tard 3 x
bip pour l’arrêt
14 Sortie de commande d’une LED (Low activ) fonction de tension d’alimentation du récepteur (les valeurs de tension dépendent
du câblage du récepteur)
Alimentation de l’émetteur forte: LED éteinte
Alimentation de l’émetteur moyenne : LED clignote
Alimentation de l’émetteur faible : LED clignote plus intensivement
15 Antenne Connexion d’une antenne métallique de 173mm ou conducteur intérieur d’un câble coaxial de 50 Ohm
16 Antenne GND Connexion de l’écran du câble coaxial pour montage séparé de l’antenne
4 Mise en marche
Pour le montage du module ou de l’antenne choisissez un endroit de préférence élevé et soustrait aux influences d’objets conducteurs.
La platine étant sans protection, veillez à éviter tout déchargement statique susceptible de détruire les
composants

Les LED ne sont pas nécessaires
pour la fonction
Réalisez le câblage nécessaire à votre application.
Antenne: L’antenne la plus simple est un fil métallique de 173mm. Connectez un câble coaxial de 50Ohm pour un montage séparé de
l’antennne.
Alimentation: Connectez la tension d’alimentation à +U (Pin10) et GND / 0V (Pin11)
Attention: Tension d’alimentation maximale 3,6V.
Une tension supérieure détruirait le module !
Emission: Testez la fonction en reliant une des 4 Entrées numériques (4, 5, 8 ou 9) à l’aide d’une touche avec GND (tension
d’alimentation négative). Les LED sur le schéma ci-dessus sont superflus pour cette fonction.
Programmation des émetteur par le récepteur : veuillez programmer au préalable les adresse des émetteurs par le récepteur selon
les instructions de ce dernier.
Divers: Pour l’application de toutes les fonctions referez à l`exemple de câblage ci joint.
