WM-WL-875 wireless digital transmission module provides standard RS-232, RS-485, and UART/TTL level interfaces for direct connection with computers / RTUs / PLCs, use's RS-485 equipment, SCM or other UART parts. WM-WL-875 uses half-duplex communication channel which is best suitable for point to the multi-point communication mode. The primary unit takes full control of communication harmony and adopts data frames with address codes for data or command transmitting.

The secondary station shall fully receive them and select response by comparing address codes; all the work shall be fulfilled by upper layer protocols, which shall ensure that only one wireless module in the communication network is in the transmitting state in any instant to avoid mutual interference. Therefore, the transmission channel built by WM-WL-875 is transparent to the user. WM-WL-875 can also be used for point to point communication, making it easier and smooth upgrade to wire (RS232/485/TTL) transmission mode in the original system.

WM-WL-875 has a low rate of data transmission, visual distance transmission distance of 2 km of wireless data transmission products. Can provide users with a two-way data signal transmission, detection, and control.
