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.

Low Battery

When the unit measures a low battery voltage level, the transmit LED flashes during transmission, and

the data transmitted includes a ‘Low battery’ status flag to the receiver decoder.

Power Supply

The circuit has been designed to operate from 2 PP3 Batteries. Always use Alkaline for long battery life..

Note: reverse voltage polarity connection will cause damage to the circuit.

Antenna

An external ¼ wave flexi antenna is supplied with this product. This has been optimised to provide

maximum range.

License Exemption

The transmitter encoders use ECM compliant radio transmitter modules and comply with ETSI330-220.

KEELOQ Protocol Configuration

All devices are supplied with a RF Solutions manufacturers ID, directly compatible for use with RF

Solutions decoders.

Each encoder is supplied ready programmed with a unique random serial number. The decoder has the

ability to memorise this serial number using a simple learn procedure (please see decoder datasheet).

How does KEELOQ technology work?

KEELOQ is based on a code hopping algorithm which provides Rock Solid Security. KEELOQ uses

a programmable 64-bit encryption key that is unique to each device to generate 32-bit hopping

code. The key length and hopping code combination reduces the possibility of unwanted access,

due to code grabbing and code scanning, to essentially zero. Such CIA-like levels of security are

desirable, but many manufacturers would expect them to be cost-prohibitive. KEELOQ offers the

solution for affordable, Rock Solid Security that is the future of technology for the cars, homes and

offices we wish to protect.

Programming the manufacturers ID / Custom Protocol Configuration

Access to the to the HCS360 KEELOQ encoder is through the connector J8.

For supply of custom programmed product please see the form ‘KEELOQ configuration template’ this is

the information we require in order to supply custom programmed devices.
