‘102 SERIES RADIO / IR ENCODER TRANSMITTERS

• Highly Secure

• QM, FM or Infra Red

Protocol

• Frequency Options; 315, 433, 915MHz

• LED Indication Of Transmission

• 1,2 or 4 Switch Versions Expandable To 15

• Power Saving Auto Shut Off Feature

• Automatically Transmits Battery Low Condition

• IP40 Rated Enclosure

• User Customisable Overlay

• Board Level Programmable

• 315MHz versions FCC Compliant

• 433MHz versions EMC Compliant

The RF Solutions 102 range of transmitter 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 paired with one of the KEELOQ Rx decoder boards, a complete high security “code hopping”

remote control system may be achieved. The transmitter is supplied as a complete product with battery

ready to operate (PP3). Each encoder can be board level programmed 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.

‘102 SERIES RADIO / IR ENCODER TRANSMITTERS

Low Battery

When the unit measures a low battery voltage level, the data transmitted includes a ‘Low battery’ status

flag to the receiver decoder.

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 polarity connection may cause damage to the circuit.

License Exemption (Radio Transmitters)

Europe: The transmitter encoders 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 Configuration

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.

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_CC.
