Compliant with SMG31bis techonical standard

Function Features

Highly intergreated with GPRS and TCP/IP technical, can achieve Point to Point( MT/MO), Point to Multipoint etc. Nimble wireless network mode.
Embedded with CPU can acchieve complicated network protocol, support PPP, ICMP, TCP, UDP, DNS protocol, offer transparent transmission channel for user data
Stable function guarantees long steady work in outdoors bad envionment, embedded softdog circuit

Support permanent online mode, user can customize heartbeat packet pattern and time interval to keep communication line working
DTU can automotive connect once again after network problem or central part shuting down

Support RS485 and RS232 connect in the same time
DTU can guarantee data transmission quality in tranparent transmission mode
DTU working in the state of transparent and user instruct mode to operate and maintain easily

Support center in the fixed IP station or non-fixed IP+ mode
Support RS232 interface, support rate from 300BPS-115200BPS, data statation /non-working station / Parity station/ocurrent control opptional
Support long-distant argument configure and visit

Support remote awaken
Embedded with Flash card, can keep the user argument configure for a long time
Support RS232 firmware to upgrate
Support APN data sepcial network affair

Anti-interfere design suits application in electromagnetism ect. Bad environment
Enhanced Functions
Industral design, need all kinds of bad environmental requirement

Select Industral device, wide-range working voltage, avert opposite connection design
Use WAVECOM GPRS wirelss Module
Embedded Multi-work operation seystem
Standard PPP, TCP/IP, UDP/IP protocol
Independent developed DDP protocol, garantee data route work smoothly
Multi-mission working mode

Permanent on-line mode: Support automotive in on-line once connect power, automotive connect after shutdown, ensure data transmite promptly
Detonate on-line mode: In standby station, data flow/voice/message can detonate equipment on-line
PCL controled on-tral part problem, can customorize a fixed time interval to connect central part by redailing again after ppp failure dial

Support multilateral communication

Channel working modes independent and can be free definited: Each channel communication mode can be definited as GPRS or SMS mode

Support main and standby channel working mode: Support automotive shift to the standby message channel transmission mode in a station of the main GPRS network shutdown

Support Multi-central working mode: Max support to connect four centrals at the same time
Nimble data transmission mode

Argument configure and Remote management

Embedded Visualization self-check rocedures in power-on dail station to exclude breakdown easily
Including Chinese /English Argument configure interface and inquiring menu
Support remote Argument configure for data central server and mobile phone message
User can definite TDP protocol pattern
