D540-X06-E30: Radiomodem UHF (HPDL868) 868MHz with integrated antenna

The D5 series includes a range of radio devices operating in license-free frequencies both VHF and UHF, differing by interface type and communicating directly with each other or through repeaters. Available interfaces include: serial port, serial port plus ethernet port, serial port plus various analog and digital inputs and outputs. Thanks to the variety of inputs and outputs, the D5 series is ideal also for data acquisition and remote control applications. They operate in the frequency bands allowed for free use by the European community: 868 MHz (D540 series) with output power up to 500mW. The good sensitivity combined with high dynamic range and high radio power allows operational distances of several kilometers.
