This product has reached end of life.

The DTS and EUR Series combine a low power 868MHz or 915MHz wireless transceiver with a powerful multipoint-to-multipoint protocol controller to form a complete wireless communication solution capable of replacing wires in almost any RS-232/422/485 application. The module has a Universal Asynchronous Receiver Transmitter (UART) serial interface that can be connected directly to microcontrollers, RS-232 converters or USB adaptors. The module automatically handles all radio functions resulting in a UART-to-antenna wireless link. The transceiver uses a wide band modulation method that is allowed to have a transmitter output power that is as high as frequency hopping systems without the overhead of managing the hopping as well as the delays in data transfer while the radio is changing channels. The DTS and EUR Series can stay on one channel and get up to 1 mile / 1.6km line of sight. It has multiple channels available to help avoid interference. The module is available in variants that use the North American, European and Brazilian frequencies. An evaluation module is available that has the transceiver on a board with an antenna connector and voltage regulator. These are pre-certified in the United States and Brazil.

Benefits

Easy integration: a complete radio, protocol and UART interface results in a complete UART-to-antenna solution
Low overhead: all configuration settings are done through the UART interface and the built in protocol handles all over-the-air functions, so very little software development is required
Simplify design: modules and antennas are the only RF components you need; no tuning required
Streamline production: save time and money with modules that are already tested
Pre-certified: Evaluation modules are already certified
