DTU introductions
AS32-DTU-1W is a 433MHz,1W industrial-grade wireless data transmission unit with high stability. The DTU uses SX1278 main chip, LORA spread spectrum transmission, RS232/485 level output.Using LORA spread spectrum technology makes the module have a longer communication distance.
AS32-DTU-1W 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.
AS32-DTU-1W operating frequency is 410MHz ~ 441MHz, a total of 32 channels, each channel’s interval is 1M.
