Protocol

Note: Standard FM units Shown, narrowband FM

transmitters include external ¼ wave whip antenna

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 Microcontroller.

(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.
