Data Outputs
Each output relay provides an isolated switch. Connections are Common (COM), Normally Open (NO) and
Normally Closed (NC).

Transmitter OPERATING
The jumper links (J1, J2) configure the outputs to be momentary of latching.
The jumper links are made / removed by a small link ‘cap’ placed over the pin header.

Combining Transmitters to receivers
Each transmitter has a unique identity, (one of 16 billion possible numbers), the identity number is encrypted
and transmitted as a random number that changes on each press of the switch. (the same number is never
repeated!). Each receiver can learn the identity of upto 50 unique transmitters.
Note : the same transmitter may be taught to any number of receivers to create ‘master keys’.
Learning a New Transmitter Keyfob Switch
1. Press the learn switch (SW1), the accept LED will illuminate.
2. Press the transmitter once, accept LED will extinguish.
3. Press the transmitter again, the accept LED will flash.
4. Wait for the accept LED to stop flashing.
5. This transmitter will now operate the system.
The system can learn upto 50 unique transmitter keyfobs
Erasing Existing Transmitters
1. To completely erase the Tx encoders, press SW1 on the Rx decoder for 10 seconds.
2. The learn LED will turn off after the 10 seconds to indicate the Tx encoder(s) have been erased
NOTE: You cannot erase individual Tx encoders
