Products description
Technical parameters
Product features

ATC-873 wireless, 868 MHz free band, 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-873 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-873 is transparent to the user.
ATC-873 can also be applied to point to point communication, making it easier and smoothly upgrade wire (RS232/485/TTL) transmission mode in original system.

Application fields:

Industrial telecontrol, telemetering, wireless message recording.
Automatic data acquisition systems, wireless label, wireless telecontrol, meteorology and hydrology monitoring.
Gate safety check on work attendance, POS system, wireless monitoring of machine room facilities.
Other wireless RS232/485/TTL data communication.

Technical parameters:

Sight distance credible transmission distance is up to 1000m (BER=10-3@9600bps). Inside buildings transmision distance up to 80m.
Offer byte-oriented transparent data adaptable to various user protocols.
Can 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.
869.40~869.65MHz ISM frequency range, need not apply for frequency pint.
Micro-power transmission, maximum 500mW.
Equipped with 50 ohm SMA antenna pedestal, offer manifold antenna options.
Meanwhile offer RS-232/RS-485/ TTL level interface (depend on type), optional I/O port.
