DESCRIPTION
The R.F. Solutions 458MHz FM Transceiver Module is a compact frequency synthesised module capable of
transmitting data up to 20 kilometres in direct line of sight, up to 1-3km within buildings. The units are
suitable for general purpose telemetry applications where small size and high data rates are needed. The
module can transmit digital or analogue (GMSK, or FSK) data at up to 9600baud rate.
The output power and frequency channel is user selectable, to ensure that an open channel may be
employed.
Supplied as a completed module, no modification or pre tuning is necessary. Connections to the module are
via a 26 way connector on the module base. The transmitter has three data inputs, Digital, Analogue, and
direct modulation. Two data outputs are provided one digital and one analogue. The transmitter and receiver
sections may be switched independently via external signal lines.
The transmitter section has three data inputs: one for Analogue Data (AIN), one for Digital Data (DIN) and one
for Direct Modulation (MIN). Two data outputs are provided from the. receiver section, these are: Digital Data
Out (DOUT) and Analogue Data Out (AOUT).
The transmitter and receiver can be switched independently by signals (TXON) and (RXON). Additional
signals are provided such as relative signal strength indication (RSSI), RF Carrier Direct (CD), Synthesiser
Locked (RDY) and Out of Lock (OOL).
The RF frequency can be set in three ways. The 6 DIL switches located at the front of the module set the
default RF frequency. This can be incremented or decremented by pulsing the input (FINC) in conjunction
with the clock input (FCLK). In addition a Serial Data Stream can be used to set the RF frequency directly
and interrogate the status of the radio. Other output signals provided are Relative Signal strength, Carrier
Detect, Synthesiser Locked, Out of Lock. The RF output power can be set between 5mW and 500mW by the
(RFADJ) signal.
This transceiver requires no licence to operate and is type approved to MPT1329 and ETSI300-220.
