For the CDP-TX-02E, CDP-RX-02E, frequency setting is performed with the 4-bit switches. Instead of these 4-bit switches, the CDP-TX-02EP, CDP-RX-02EP have 8-pin connectors for frequency setting, making it possible to set the channels externally.
There are no other technical and mechanical differences between CDP-02E and CDP-02EP.
The CDP-TX-02E/EP and CDP-RX-02E/EP are RoHS compliant, embedded industrial narrow band 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-02E / EP and CDP-RX-02E / EP are equipped with a frequency synthesizer system with micro controller. Available frequency ranges are from 32 preprogrammed channels. The compact size, low operating voltage and frequency selectability of the CDP-02E make it ideal for various applications where its interference rejection and propagation distance range is far better than similar RF modules based on wide band SAW-resonator frequency generators.
The CDP-RX-02E / EP receiver has excellent blocking and adjacent channel selectivity.
