DESCRIPTION
The RF Solutions KEELOQ range of miniature pocket Keyfob encoders are available as Radio of Infra Red
transmitters.
When paired with one of the KEELOQ Rx decoder boards, a complete remote control system may be
achieved, with comprehensive interfacing capabilities. This may also be high security “code hopping”
The keyfobs are housed in a tough ABS enclosure and supplied with Battery ready to operate.
An membrane overlay sticker is used to indicate the switch positions which may be customised to
incorporate a specific logo or mark.

Operation
The Tx encoder transmits the KEELOQ code for as long as any push-button switch is depressed.
Operation of the Tx encoder buttons will cause either a momentary or a latching action at the Rx decoder,
depending on the configuration of the Rx decoder.
Battery Supply
The keyfob is supplied with a standard cigarette lighter 12V battery type GP23A or equivalent.
Low Battery
When the unit measures a low battery voltage level, the data transmitted includes a ‘Low battery’ status
flag to the receiver decoder.

Auto Shutoff Feature
After ~26seconds of continuous transmission the Keyfobs are programmed shut down. This is to prevent
the battery being drained through accidental operation (i.e. if it is in the users pocket!). This feature can be
removed by re-flash programming of the unit.
License Exemption
The transmitter encoders use EMC compliant radio transmitter modules and complies with ETSI330-220
and ETSI300-683.
USA : This device complies with part15 of the FCC rules.
Operation is subject to the following two conditions:
1. The device may not cause harmful interference, and
2. This device must accept any interference received including interference that may cause undesired
operation.

Building a Receiver Decoder
Any of the keyfob Tx Encoders may be decoded with one of the complete RF Solutions receiver decoders
or by using the appropriate receiver and RF600 decoder I/C. Schematic design is given in the datasheet for
RF600 (DS600)
Further Information: Developing a Keeloq Based Decoder System
The RFEVAL3 is an Evaluation Board consisting a receiver decoder board. The board can accept
several RF Receivers and RF6000 decoding I/C providing a hardware development
platform to enable the integration of remote Control.
