- E90-DTU(433L30)-V8 is a wireless data transceiver of 433M with standard RS232/RS485 connectors. They are half-duplex. TX & RX modems with LoRa technology and transparent transmission mode. Voltage supply ranges from 8V to 28V, Working frequency: 410~441MHz (Default:433MHz).
- The LoRa direct sequence spread spectrum technology enables the longer communication distance and better power density concentration as well as superior anti-interference ability.
- The FEC algorism enables higher coding efficiency and correction ability. The interfered data packets will be corrected proactively upon sudden interference, which significantly improves reliability and communication distance. Without FEC, the interfered data packet will be dropped.
- The transceivers feature data encryption and compression. The data transmitted in air features randomness, the rigorous algorism makes data interception meaningless.
- The data compression function has possibility to reduce the data transmission time, which in tur reduces the possibility of being interfered, thus improves the reliability and communication efficiency.
- E810-DTU (1RS1E) is a single serial port server that transfers RS232 & RS485 & RS422 to ethernet. It realizes data transparent transmission between RJ45 and RS232 or RS485 or RS422.
