AN-WF-RS-300M/500M/1000M/2000M wireless digital transmission module offers standard RS-232, RS-485 and UART/TTL level interfaces for direct connection with computers, use’s RS-485 equipments, SCM or other UART parts.

AN-WF-RS-300M/500M/1000M/2000M has adopted half duplex communication channel most suitable for point to multi-point communication mode. The primary station 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 AN-WF-RS-300M/500M/1000M/2000M is transparent to the user. AN-WF-RS-300M/500M/1000M/2000M can also be applied to point to point communication, making it easier and smoothly upgrade wire (RS232/485/TTL) transmission mode in original system.
