GF-3008 CDMA IP MODEM(DTU)
1.General At recent years, 2.5 Generation mobile network CDMA 1x)
has been widely used in many countries, it provides a wide range
and reliable mobile data channel for business and industrial
applications, especially in M2M field. Beijing Garefowl New-tech
Co., Ltd. has developed an amazing and easy using GF-3008W/N CDMA
DTU for those applications. GF-3008W CDMA IP MODEM(DTU) is a plug
and play communication Terminal for connecting any equipment with
RS232/485 interface port to the Internet ,Including all the
software and hardware components needs to transfer information
remotely via the CDMA mobile networks .GF-3008W unleashes the power
of M2M for a large range of equipment.GF-3008W CDMA IP MODEM(DTU)
is a new designed platform, supports CDMA network. There are many
improvements, such as industrial class pluggable terminal, embedded
RTOS and embedded TCP/IP stack driving by AT+I command interface
and Enhanced EMI design.2.Overview GF-3008W CDMA IP MODEM(DTU)
enables various kinds of legacy devices with serial port to
communicate over CDMA network and the Internet easily and freely.
It not only works as a CDMA Modem, but also can construct a smooth
"CDMA Data Tunnel" between Host End and Remote End, ensuring an
efficient communication for data transmission and remote device
management. With 1 selectable RS-232/TTL/485 serial port, GF-2008
CDMA DTU is an ideal solution for factory automation, environmental
monitoring and remote device management for M2M industry.
Meanwhile, it is supplied with simple software interface that
streamline application development process, freeing system
integrators from dealing with complex communication protocols of
CDMA and the Internet. Users do not need to change the existing
system, saving cost and time for field maintenance, and making it a
perfect solution for data transmission.3.GF-3008W CDMA IP
MODEM(DTU) Features1) Transparent data transmission
GF-3008W CDMA IP MODEM(DTU) provides transparent data transmission
(RS232 or RS485 interface) for machine to machine connectivity.2)
Non host support
Normally, CDMA Modem can be connected to a PC, and then dial an
access number manually; it utilizes PC??s OS resources to finish
the data transmission and protocol conversion. GF-3008W CDMA IP
MODEM(DTU) is a powerful communication terminal in witch the
microprocessor, TCP/IP stack and application software are embedded
; it works automatically without host PC.3) Point to point, and
multi-point to point data transmission
GF-3008W CDMA IP MODEM(DTU) can be configured working in point to
point, multi-point to point and center to multipoint network frames
.4) Always online
GF-3008W CDMA IP MODEM(DTU) will automatically attach to CDMA
network when the power is on, and then set up one up to ten sockets
to the center server..5) cost saving toll
GF-3008W CDMA IP MODEM(DTU) can work ??always online?? state, and
only be charged when data transmitted.6) High speed
Maximum CDMA bandwidth can be 171.2Kb/s, only 40~100Kb/s can be
reached at actual application. 7) Simple and flexible to use
GF-3008W CDMA IP MODEM(DTU) is a powerful and easy to used device.
It is easy to build your own private mobile data network at
anywhere.
