Listning ID 104550 Description
Series of radio modems is a complete dual-radio, operating in the range of 400-470MHz,868MHz,915MHz2,4 GHz, while the useful signal power from 10 to 5000 mW., allowing to organize high-speed, wireless data transmission distance up to 5000 meters or more between two devices with TTL/UART (RS232/RS485 via adaptor) interfaces. Thanks to the integrated microcontroller, the radio transmit data in transparent mode. The use of coding of the transmitted signal, i.e., the use of a specific Protocol, allows you to deliver information even in the presence of interference. High sensitivity ensures reliable data transmission even in industrial conditions. For device configuration provided a program for PC that allows you to specify the working frequency channel, the parameters of the UART interface and optimal data transmission rate in the radio channel. The advantages of the module include a wide temperature range, small size and weight. Designed to build: systems industrial telemetry, data acquisition from various sensors, counters, water meters; wireless systems, security, alarm, fire alarm; control (monitoring) of process parameters, implementation, access control and management systems of ventilation, smoke exhaust and other engineering equipment of remote stationary objects.
