Press Release Summary:
Equipped with input and output circuitry, CDT-TX-02M-R/CDT-RX-02M-R Transmitter/Receiver Modules enable communication with up to 6 contacts. MSK modulation and receiver sensitivity of -120 dBm ensure noise immunity and stable communication, while battery-operable 10 mW transmitter offers 1 km line-of-sight range. Users can select from 4 preprogrammed frequencies using DIP switches. To prevent errors caused by receiving signals from other transmitters, each transmitter has specific 32-bit ID.
Original Press Release:
New Integrated Radio Modules for Long Range Wireless Remote Control
Circuit Design, Inc. has announced the release of the CDT-TX-02M-R / CDT-RX-02M-R, an embedded low power radio transmitter and receiver suitable for long-range On/Off remote control.
The modules incorporate highly reliable radio components and input and output processing circuitry, enabling simple communication with up to six contacts.
MSK modulation and high receiver sensitivity (-120 dBm 12 dB SINAD) ensures good noise immunity and stable communication, while the battery operable 10 mW transmitter has a line-of-sight range over 1 km.
You can select from four preprogrammed frequencies using the onboard DIP switches, allowing simultaneous use in the same area. The frequencies take third-order intermodulation into account and are programmed to have little impact on each other.
Each transmitter module has a specific 32-bit ID to prevent errors caused by receiving signals from other transmitters operating on the same frequency. The safety of this system is amply demonstrated by Circuit Design's remote control units where this system is being used in more than 1 million units.
A total of up to 100 transmitter IDs can be registered in the receiver. This ensures that control of the receiver from multiple transmitters, or control of multiple receivers from one transmitter can be performed without any concern about malfunction.
The interface for the output port of the receiver uses photo MOSFET, enabling direct drive with loading of up to AC/DC48 V/100 mA. In addition, you can select from four operation modes (continuous, toggle, switching, and one shot) depending on the requirements. In the continuous mode, the output port is active while the unit is receiving a signal from the transmitter. In the other modes, the status of the output port being controlled can be changed according to the mode setting when the unit receives momentary signals from the transmitter. When output from the transmitter is of short duration, the impact on other equipment using the same frequency can be minimized. The radio waves are used more efficiently and the transmitter consumes less power.
The technical features and applications of CDT-TX-02M-R / CDT-RX-02M-R are as follows.
