1. Product Overview
Broadcom Technology Co., Ltd. Shenzhen Gold KB3000 GPRS DTU
developed to provide users with high-speed, always-on, and
transparent data transmission virtual private communication
network. DTU is based on the Chinese mobile telecommunications
operators in GSM / GPRS communication network data transmission and
remote monitoring devices, using today's cutting-edge core
technology, an industrial-grade design of wireless communication
terminal products for GSM / GPRS network coverage within the scope
of a variety of indoor or outdoor harsh environment, primarily for
the electric power system automation, industrial control, traffic
management, meteorology, environmental monitoring, mining, finance,
securities, oil and other industries applications, the use of GPRS
network platform for data transparency of information transmission,
and by auxiliary means to achieve control of the DTU to form a
user-specific data network. It can be easily with the Company's
KB2000 network switches for networking and communications.
2. Product Features
* High-performance industrial grade communication module, combined
with remote data (monitoring) transmission characteristics of the
product's stability, reliability, security, and power supply
systems, etc. have been carefully designed with consideration to
support dual-band network.
* With advanced embedded core and circuit design, job stability,
and communication reliability are stronger protection. A strict
anti-jamming design, you can 2KHz / 4KV pulse interference and
stable operation.
* Equipment, terminal equipment and the DTU connections: Use the
serial port with a large number of collector, RTU terminals, PLC
terminals, industrial computer, GPS vehicle locator,
instrumentation, POS terminals and other equipment connected to
achieve full transparency in two-way transmission.
* High-speed transmission: GPRS network, the fastest transmission
speed up 171.2Kbps, the rate is decided by the mobile operator's
network settings, according to China Mobile's network, are now
available 20 ~ 40Kbps stability of data transmission.
* Always-on, according to traffic billing: DTU automatic power-on
dial-up Internet access, has been online, break automatically
redial. Receiving and sending data packets in accordance with the
quantity of charge, there is no data traffic, no charge.
* Application of flexible and convenient: DTU uses standard RS-232,
RS-485, TTL interface, and universal binary I / O interface, only
with the user device, insert the SIM card, connected to the power
supply to work properly.
* Networking simple, fast and flexible: Do not depend on the data
exchange center operator interface device, anytime, anywhere
through the Internet to build networks covering the whole of
China's mobile data communication private network.
Support for multiple operating modes, in addition to providing
standard general-purpose functions, but also the special needs of
the user customization features.
* Built-in watchdog, with abnormal re-starting. Using a variety of
judgments and error correction mechanisms to ensure the long-term
stable operation of DTU.
