They are both compatible with the CDP-TX-04S-R transmitter and CDP-RX-03AS-R receiver, earlier models of the same modules that were very well received in the Japanese and European markets for their quality and reliability. They also come with several new functions.
While the earlier models had just one RF channel, the new models are programmed with four channels. In addition, within the main ISM frequency band* of Sub-1 GHz, the frequency table can be customized according to the customer’s requirements.
* 426 MHz in Japan, 434 MHz, 869 MHz in Europe, 915 MHz in the US
Using a TCXO as the reference oscillator circuit of the radio component ensures high frequency stability, and while the operating temperature range of the earlier product was -10°C to +60°C, in the new product it is increased to -20°C to +65°C.
With the output of 10 mW * authorized for narrow band FM and double superheterodyne receivers with high receive sensitivity in the European harmonized ISM band, a communication range of 600 m (line-of-sight) is possible.
* 5 mW in 869 MHz, 1 mW in 426 MHz, 0.5 mW in 915 MHz
