General introduction: ATC-873 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-873has 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. Ø Technical parameters: Sight distance credible transmission distance is up to 1000m(BER=10-3@9600bps) 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 429.00~433.30MHzISM 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 Effective speed 1200/2400/4800/9600/19200/38400bps Working temperature is -20 oC ~70 oC (common)/-35 oC ~70 oC ( industrial class) Transmitting current: ≤360mA /receiving current: ≤45mA(1200bps) Ø Application fields: Industrial telecontrol, telemeteringwireless 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 Download: ATC-873 Mini Power Wireless ModuleUser's Manual-PDF ATC-873 CE Declaration of Conformity -PDF SẢN PHẨM V.I.P CÙNG NHÓM Thiết bị lặp sóng GSM 5000 series splicing LCD (Four channel signal splicing upgrade series) 3000 series splicing LCD (vertical display series) speed dome module
