The RF Solutions 102 range of transmitte r encoders are available as either FM, FMNB radio or Infra Red.
The encoders use the KEELOQ encryption algorithm providing the worlds most advanced high security
protocol. Each encoder may be used with one of RF Solutions decoders, or with one of the KEELOQ
decoder I/C’s.
Alternatively, the user may decode the KEELOQ algorithm and embed within a PIC Microcontrolller .
(Please see datasheet DS600).
When pair ed with one of the KEELOQ Rx deco der boa rds , a complete high security “code hopping” remo te
control system m ay be achieved. T he transm itter is supplied as a com plete product with batter y ready to
operate (PP3). Each encoder can be board level programm ed with a specific manufacturer’s ID code if
required
Custom solutions may also be supplied unique to customer specific requirements. Please contact RF
Solutions for further information.

Low Battery
When the unit measures a low battery voltage level, the data transmitted includes a ‘Low battery’ status
flag to the receiver decode r .
Power Supply
The circuit has been designed to operate from a single PP3 battery supply. This will provide in excess of
1,000,000 transmissions.
Note: reverse voltage polarit y connection may cause damage to the cir c uit.
License Exemption (Radio Transmitt ers)
Europe: The transmitter encoder s use ECM compliant radio transmitter modules and complies with
ETSI330-220 and ETSI300-683.
USA: This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received, including interference that may cause
undesired operation."
KEELOQ Protocol Config ur ati on
Each encoder is supplied read y progra mmed with a unique random serial number. The decoder has the
ability to memorise this serial number using a simple learn procedure (pleas e 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 c ode.
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, Roc k Solid Security that is the future of technology for the cars, homes and offices we
wish to protect.
Adding Additional Switches
Additional switches may be added through Connector J1. The four connections of J1-1, 2, 3, & 4 represent
the four input lines to the HCS360 encoder device. These may be connected to a binary coded decimal
(bcd) input to obtain 1 of 16 states. Connection J1-6 is connected to V
