For the CDP-TX/RX-02F-R, frequency setting is performed with the 7-bit switches. Instead of
these 7-bit switches, the CDP-TX/RX-02FP-R has 14-pin connectors for frequency setting,
making it possible to set the channels externally.
There are no other technical and mechanical differences between CDP-02F-R and CDP-02FP-
R.
General description
The CDP-TX-02F-R and CDP-RX-02F-R are an RoHS compliant, embedded industrial narrowband
FM radio transmitter and receiver.
They are suitable for various application fields such as wireless data communication, remote control,
telemetry or wireless security systems. They are easy to use and integrate into application systems.
Both CDP-TX-02F-R and CDP-RX-02F-R are equipped with a frequency synthesizer system with
micro controller. Available frequency ranges are from 433.1875 MHz to 434.7750 MHz (128 channels).
The compact size, low operating voltage and frequency selectability of the CDP-02F-R make it ideal
for various applications where its interference rejection and practical distance range is far better than
similar RF modules based on wide band SAW-resonator frequency generators.
The CDP-RX-02F-R receiver has excellent blocking and adjacent channel selectivity.
