Wireless data transceiver with standard RS232 and RS485 interfaces. These are half-duplex TX and RX modems with LoRa technology and a transparent transmission mode. Supply voltage range from 8V to 28V, operating frequency: 425-450.5MHz (default: 433 MHz)
LoRa spread spectrum technology with direct sequence ensures greater communication distance and better power density concentration, as well as excellent anti-interference ability. The FEC algorithm provides higher coding efficiency and correction capability. Corrupted data packets will be proactively corrected in case of sudden interference, which significantly improves communication reliability and range. Without FEC, a corrupted data packet will be discarded. The transceivers have encryption and data compression. Data transmitted over the air is characterized by randomness; a rigorous algorithm makes data interception more reliable. The data compression function has the ability to shorten data transmission time, which in turn reduces the possibility of interference, thereby improving communication reliability and efficiency.
