Atc-871 Mini Wireless Converter For 500 Meter - Color: White

ATC-871 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.ATC-871 has
adopted half duplex communication channel most suitable for point to
multipoint 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-871is transparent to the user. ATC-871
can also be applied to point to point communication, making it easier
and smoothly upgrade wire (RS232/485/TTL) transmission mode in original
system.
