Detailed Description

1.General At recent years, 2.5 Generation mobile network (GPRS and 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-2008W/N GPRS DTU for those applications. GF-2008W GPRS 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 GPRS mobile networks .GF-2008W unleashes the power of M2M for a large range of equipment. GF-2008W GPRS IP MODEM(DTU) is a new designed platform, supports GPRS 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-2008W GPRS IP MODEM(DTU) enables various kinds of legacy devices with serial port to communicate over GPRS network and the Internet easily and freely. It not only works as a GPRS Modem, but also can construct a smooth "GPRS 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 GPRS 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 GPRS 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-2008W GPRS IP MODEM(DTU) Features 1) Transparent data transmission GF-2008W GPRS IP MODEM(DTU) provides transparent data transmission (RS232 or RS485 interface) for machine to machine connectivity. 2) Non host support Normally, GPRS 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-2008W GPRS 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-2008W GPRS 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-2008W GPRS IP MODEM(DTU) will automatically attach to GPRS network when the power is on, and then set up one up to ten sockets to the center server.. 5) cost saving toll GF-2008W GPRS IP MODEM(DTU) can work ??always online?? state, and only be charged when data transmitted. 6) High speed Maximum GPRS bandwidth can be 171.2Kb/s, only 40~100Kb/s can be reached at actual application. 7) Simple and flexible to use GF-2008W GPRS IP MODEM(DTU) is a powerful and easy to used device. It is easy to build your own private mobile data network at anywhere. 4.GF-2008W GPRS IP MODEM(DTU) Functions Basic Functions Ease to use, reliable and flexible Support dual band GPRS network ??Optional quad band GSM/GPRS 900/1800MHz?? Always online Real clock Built-in Watch Dog Enhanced Functions Transparent data transmission(serialNet function) Support virtual private data network (VPN) Support DDNS or IP address Continuous and automatic GPRS VPN Management (GPRS Data Tunnel) STK/UTK card configuration Support TTL/RS-232/422/485 interface Voice interface System configuration & maintenance interface Self-diagnostic and alarm output EMC/EMI design Enhanced and widely power supply design Industrial class pluggable terminals interface Industrial design with surge protection 5.Advantages & Benefits Industrial design with intelligent software capabilities, making it a reliable GPRS solution for data collection and transmission Let any devices with serial port connect to the GPRS network or internet via mobile network. Plug-and-play design with easy-to-use software interface for easy integration No need to build expensive fixed line network, saving cost substantially Easily manage and control distributed remote devices over the air Reliable GPRS network connectivity, providing fast and cost-effective long-range wireless communication 6.Specifications General Specifications Processor Environment Low power-consumption CPU, 128KB SRAM Power Consumption <1.4W (GPRS online), 2W (searching GPRS), <360mW (idle) Voltage 5~25VDC(9V Suggest) LED Status Indicator Power/Ring/Net Data Logger Capacity N/A Firmware Upgrade through serial port or by air interface Parameter Setting through serial port or by air interface Protocol Supported TCP, UDP, ICMP, PPP GPRS Spcifications GPRS Multi-slot Class 8 GPRS Mobile Station Class B Download/Upload (Max.) 85.6Kbps/21.4Kbps Code Scheme CS1, CS2, CS3, CS4 PPP-Stack Yes Module Approvals GCF, R & TTE Frequency 900/1800MHz Interface RS-232/422/485 1 RS-232 N/A Analog Input N/A Digital Input/Output N/A Mechanical Specifications Operating Temperature -20 C~60 C Storage Temperature -30 C~80 C Humidity 5%~95% RH Regulatory Approvals CE, FCC Dimensions (L x W x H) (mm) 75*50*16mm Weight (g) 160mg SIM Card Holder 3V/5V Connector RS-232/TTL/485 Terminal Block serial port/power SMA F External Antenna Connector Yes DIN-rail Yes 7.GPRS Mobile Data Communication System Applications GF-2008W GPRS mobile data system is a universal communication system for industries and utilities services. It adapts to all applications that require medium and low rate data communication, such as power distribution network, running water, gas pipe, weather station, traffic control, POS and so on.
