I: Application of KYL-668H
Applicable Field: Shipping, traffic, interphone system of taxi,
industrial automatic control, electric power schedule, water
conservancy monitor, signal collection and transmission of railway
system, oil extraction and transportation control, measure of oil or
water wells, hydrological monitor, weather information transmission,
environment monitor, container management, goods management in
supermarket, forest protection, intelligent building, wireless
beaconing, geological reconnoiter, mobile location, military training,
public security, medical ward, remote controlling and remote
detecting, and others automatic control fields.
KYL-668H Data Transmission Radio Station is a high performance
professional data transmission radio station combined DSP
technology and software wireless technology.
II: Product Characteristic：
O Modulate and demodulate algorithm is realized by software using
advanced and reliable DSP technology for high speed digital signal.
O High speed digital signal transmission is realized by adopting
advance communication algorithm such as wave-form transaction
and bandwidth compress etc.
O To get best receive performance, quickly self-adapt equilibrium
technology is adopted to eliminate the ware-form distortion caused by
multi-path, (relay) group delay during the transmission.
O Combination of powerful feedforward put right code
GF(256)Reed-Solomon and complect algorithm guarantees reliable
communication in the bad environment.
O With CRC-ARQ function and 16bit circular verification code, it will
require automatically re-sending the data when the error code occurs
during data verification.
O Watchdog is used to prevent from shutting down caused by the
disturbance in the industrial environment.
O Self-adapt transmission speed; adjust automatically among
19200/14400/9600bps according to the quality of signal channel.

Shenzhen KYL Communication Equipment Co., Ltd
O double phase-lock loop, double VCO structure, high stability.
O Standard TTL, RS232 (or 485) interface; directly connect to Single
Chip or Personal Computers.
O Set transmit frequency and change channel and work mode by
computer.
O Using divided packed transmission, it can be used to construct a
wireless grouping data communication net, maximal 254 users in the
net.
O Support AT instruction, user can set running parameters and
status by software.
O All products adopt surface paste technology, which guarantees the
stability and reliability of the products.
O Flexible net building protocol: support several net building mode
such as full transparency, poll, CSMA(carrier wave ?? multi-address)
etc.
