DTU introductions


 AS62-DTU20 is a 433MHz,100mW industrial-grade wireless data transmission unit with high stability. The DTU uses SX1278 main chip, LORA spread spectrum transmission, RS232/485 level output. The DTU adopts the efficient cyclic interleaving error correction coding algorithm, which has high coding efficiency and good error correction ability. In the case of sudden interference, the DTU can correct the interrupted data packets, and the maximum continuous error correction is 64bit, which greatly improves the DTU’s Anti-jamming ability and transmission distance, and in the absence of error correction algorithm, this error packet can only be discarded. Using LORA spread spectrum technology makes the module have a longer communication distance.
 
AS62-DTU20 has two kinds of operation modes and can be switched when needed. Transparent transmission mode is use for data transparent transmission. Configuration mode is use for changing the communication parameters of the DTU.
 
AS62-DTU20 operating frequency is 410MHz ~ 441MHz, a total of 32 channels, each channel’s interval is 1M.
