Featrue:
E32-DTU(915L30) is a data transfer unit (DTU) based on originally imported RFIC SX1276 from SEMTECH, with RS232/RS485 interface, 8V~28V, operating at 900~931MHz (Default: 915MHz). It features LoRa spread spectrum. Transparent transmission is available.
The DTU adopts LORA spread spectrum technology, which means the transmitting distance is much longer than before. The advantages include more concentrated power density and better anti-interference performance. It features FEC (Forward Error Correction) algorithm, which ensures its high coding efficiency & good correction performance. In the case of sudden interference, it can correct the interfered data packets proactively, so that the reliability & transmission range are improved correspondingly. But without FEC, those data packets can only be dropped.
The DTU has the function of data encryption & compression. The data transmitted over the air features randomness.
