CDP-TX-02E-R / CDP-RX-02E-R / CDP-TX-02EP-R / CDP-RX-02EP-R: 457 MHz0 pages
32ch
UHF Narrow Band Multi Channel Transmitter/Receiver
CDP-TX-02E-R, CDP-RX-02E-R 457 MHz
The unique and compact CDP - TX/RX - 02E - R 457 MHz is a frequency selectable radio data module.
Both CDP-TX-02E-R (transmitter) and CDP-RX-02E-R (receiver) are equipped with a frequency synthesizer system including microprocessor.
32 RF channels are selectable using an onboard 4-bit switch. Its small size, low voltage
operation, and frequency selectability of CDP-02E-R make it ideal for various
applications in sites where many radio transmitters are operated.
