Press and release the programming switch (PSW1)
Note that the LED will illuminate
Depress and release the transmitter once, LED on the decoder will extinguish
Depress and release the transmitter again, LED on the decoder will flash
After the LED has stopped flashing the transmitter has been successfully taught to the decoder
This transmitter will now operate the system
To completely erase the transmitters, press PSW1 on the decoder for 10 seconds. The LED will turn
off after the 10 seconds to indicate that the transmitter(s) have been erased
Synchronisation (Hopping Models Only)
This equipment requires the transmitter and receiver to be synchronised. If the transmitter has been
pressed more than 50 times outside the range of the receiver, the receiver will loose synchronisation with
the transmitter. To re-synchronise, press the transmitter twice within range of the receiver.
Antenna Design
For 99% of applications a 16.5cm piece of wire is quite adequate. The range achieved from the system is
dependent on the choice and position of the antenna. The space around the antenna is as important as
the antenna itself. The optimum position is to locate the antenna so that it protrudes directly out the top of
the transmitter box. If this is not possible due to other design constraints try to keep the antenna away
from other metal in the system such as transformers, batteries and PCB tracks, especially ground planes.
In particular the ‘HOT’ end of the antenna should be kept as far away as possible from these.
For further information on antenna design please see our full product catalogue.
Minimum Output Time
The following timing can be used to calculate the minimum on and off time for the outputs on the Keeloq
decoder.
Button press on encoder to output on decoder changing state <100mS
Button release on encoder to output on decoder going to original state < 300mS
Data Outputs
Output 1 is used to drive the on-board relay (if fitted), it is an open collector type output.
Outputs 2,3 & 4 are digital CMOS/TTL with a series 220Ω protection resistor
The outputs are configured by Link 1 & 2
Removal Of Relay
If the relay is not required, remove the connecting links “CK1” & “CK2”. The PCB may then be carefully
broken along the score lines between the relay and the rest of the board.
