FMR-05D
27 MHz RADIO DATA RECEIVER
The FMR-05D radio data receiver is used for long distance digital data communications. The small
size and low power consumption makes the FMR-05D most suitable for portable applications. The
fully screened metal housing makes it less susceptible to interference. Together with its low cost it
allows for this data receiver to be used in many diverse applications.

The FMR-05D receiver and the FMT-2705 can be combined to form a transceiver. This transceiver has
a reliable operating range of up to 2100 metres in open field conditions and at speeds of 2400 bps.
The +5 Volts connection is the supply connection.
The Ground connection is used for the supply and shield connection if a coaxial cable is used with the
antenna. Ground connection for shield connection is next to the antenna pin.
The Antenna connection is used for the antenna connection
The Data connection output is for the digital data received at 0 to 5 Volts.
The Signal Strength connection is a Relative Signal Strength Indicator. See below chart for output
levels.
