General introduction:
ATC-863-S2 wireless digital transmission RF module offers standard RS485 and UART/TTL level interfaces for direct connection with computers, use's RS485 equipments, SCM or other UART parts,
ATC-863-S2 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 ATC-863-S2  is transparent to the user.
ATC-863-S2  can also be applied to point to point communication, making it easier and smoothly upgrade wire (RS485/TTL) transmission mode in original system.

Technical parameters:
1,Sight distance credible transmission distance is up to 300m 
2,Offer byte-oriented transparent data adaptable to various user protocols 
3,can be applied to manifold communication combination methods like point to point, point to  multi-point and multi-point to point
4,Automatically filtrate fake data generated in air, can transmit longer data frames
