Long-distance Wireless PTZ Command Transmission Equipment
( Transmission Distance : 30 km)
Features: High-speed digital signal processing DSP technology with software means to achieve the modulation and demodulation algorithm to ensure the advancement and reliability The use of advanced communication algorithms, such as waveform processing, bandwidth compression technology, high-speed digital signal transmission The use of fast adaptive equalization to eliminate because of multi-path transmission, (relay) group delay due to wave distortion, aliasing for the best receiver performance Super FEC GF (256) Reed-Solomon code and interleaving algorithm is a combination of poor communications environment in the Bulgarian political reliability of the communication With CRC-ARQ function, uses 16bitCRC cyclic check code, there is error when the data validation, it can automatic repeat request. Watchdog designed to prevent interference in industrial environments accidental crashes. Channel rate adaptive function of the quality of the situation according to the channel between the automatic adjustment in 19200/14400/9600bps
The double-loop, double-VCO structure, high stability Interface with standard TTL, RS232 (or 485) level, can be directly connected microcontroller or PC Used the computer to set transmission frequency, change the channel, determine the mode of Sent by the sub-way, can form a wireless packet data communication network, the largest network supports 254 users Support the AT commands, the user can run the software on the station set parameters and states The product uses surface mount technology to ensure stable and reliable quality of products Flexible networking protocol : to support fully transparent, polling, CSMA (Carrier Sense Multiple Access) network formation etc.
