‘001’SERIES RADIO RECEIVER DECODER MODULES. • Miniature RF Receiver /Decoder • Keeloq Protocol • 40 Pin DIL I/C Profile • Single Relay Option Available • Supplied As AM or FM • LED Indication Of Data Reception • Easy Learn Transmitter Feature • CMOS/TTL Outputs, Momentary or Latching • Single Supply Either 5V or 12V • Contacts 2A @ 12V • Available 433Mhz @ 10mW • Requires No Radio Licence Applications • General Remote Control Systems • Garage Door Openers • Car, Caravan, Motorcycle Alarms • Remote Switching • Remote Gates • Paging Description This range of miniature modules are complete four channel RF receiver/decoders that can be configured for many different low power short range telemetry applications. All modules are plug-in dual-in-line (DIL) package with the same profile as a standard 40pin DIL I/C for easy PCB mounting. A single relay option is an extended length module (removable) containing a BT/47 type relay. The module requires connections to the power supply 5Vdc or 12Vdc and data outputs only. The unit may be supplied with one of two AM receivers or an FM receiver configuration. An LED indicates data reception. Each decoder is compatible with any KEELOQ transmitter/encoder. The decoder has an easy-to-use 'LEARN' facility to allow the decoder to learn up to 50 transmitter/encoders.

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
