Made in China & assembled in FIJI for ELSEMA PTY LTD. The FMR-202 is a crystal controlled single channel receiver, comprising of receiving, decoding and open collector output sections. A specially designed LARGE SCALE INTEGRATED CIRCUIT (LSI) is employed in the decoder section, which ensures operation at low supply voltage, highest reliability, associated with very low power drain.
The receiver works on a digitally encoded 27 MHz frequency modulated (FM) signal. It may be used in an application that requires the 27MHz receiver to be mounted on a printed circuit board. If the code of the input signal (from a transmitter) matches the setting of the coding switch on the receiver (up to 4096 combinations), an output is obtained i.e. the open collector is switched to ground.
Elsema’s ANT27MHz series antennas will give a reliable control range of up to 200 metres, when used with
Elsema’s FMT-301, FMT-302 and FMT-304 transmitters.
The default mode is in momentary mode, i.e. the output transistor is only activated while the correct signal is
received. When a latching mode (toggling the output every correct incoming signal) is required the latching link
should be soldered into the receiver. In latching mode, the output transistor is on at the initial "power-up".
Care must be taken, not to bring a receiver near strong magnetic fields, such as DC-Motors, speakers, magnets for
reed switches, transformers etc. as it would magnetise the coils and may cause severe de-tuning.
