General introduction:
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 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-871 is 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.
Technical parameters:
Sight distance credible transmission distance is up to
500m(BER=10-3@9600bps);
Offer byte-oriented transparent data adaptable to various
user protocols;
Ccan be applied to manifold communication combination
methods like point to point, point to multi-point and multi-point
to point;
Automatically filtrate fake data generated in air, can
transmit longer data frames;
Modulation mode basing on FSK, adopts high efficiency
forward error correction channel coding technology, anti-jamming
data;
429.00~433.30MHzISM frequency range, need not apply for
frequency pint;
