GPRS DTU Data Terminal Unit

Hi I would like to have brief information as well as the feature of the GPRS DTU (Data Terminal Unit)?

GPRS DTU (Data Terminal Unit) is remote information transmitting terminal of GPRS/SMS and implanted with High solid ARM7 CPU.

In light of people in general net, GPRS DTU transmit broadly, steadily and dependably, GPRS DTU is broadly utilized as a part of unattended operation gadget, Remote AMR, remote information obtaining, remote AMR, remote planning and so on.

GPRS DTU is utilized as a part of electric power programmed framework, industry checking, activity administration, climate, master environment, pipe arrange observing, back, securities divisions et cetera. Consider the systems administration ask for from various application scope, accomplish Virtual information private system in system structure. It is material to little and medium information transmitting of the Center to multi-focuses, multi-focuses dissipate

Highlights

Standard modern items, EMC against sticking plan

Free research, inserted 32 bit ARM7-CPU with continuous working framework.

Installed Watchdog chip, give various Reset instrument, can be controlled by programming, accomplish modern security component superbly.

Working Frequency embrace 850MHz/900MHz/1800MHz/1900MHz which is suit for each nation everywhere throughout the world (Including North America and South America);

Progressed and strict information correspondence convention, with the capacity of rectification and encryption.

Never lose bundle when information transmission, can accomplish pictures over than 100K and Flash activity documents transmission, no Mosaic happened.

Different working mode: DTU (default), Modem, SMS Modem. DTU mode is GPRS information transmission which can get the information from gadgets COM port (RS232/RS485/TTL) and transmit to the server in Internet. It additionally can get SMS Message when DTU mode (it needs to switch IO port to SMS when send message). SMS Modem is SMS transmission mode, client can set to sort A (with convention) or sort B (straightforward). At the point when set to Modem, perfect standard AT order (GSM07.05 and 07.07). Client can compose AT order programming to understand the capacity client require.

DTU and SMS Modem can switch through User arrangement programming furthermore can change the working modem through IO port. Set the parameter of Modem mode should after it is power-on.

SMS Modem highlight:
Different systems administration courses: Under SMS Modem, the gadget with convention (A) can coordinate with the gadget without convention (B), the gadget with convention (An) additionally can coordinate with the gadget with convention (A).

Under SMS Modem, can get and send the MAX information 1024 bytes a period.

Under SMS Modem, bolster Sending and Receiving Data shape: HEX, ASC II, UCS2. Client is encouraged to set this parameter through our setup programming before utilize it.

Different systems administration routes, distributed, focus to multi-focuses.

Consequently IP enroll system, can accomplish different server modes, construct finish super vast SCADA framework.

Remote rest and alert: User can utilize delegated mobile phone number to dial or send message can rest or alert DTU, it is helpful for client to spare a considerable measure of GPRS Flow Fee when no compelling reason to utilize DTU.

Remote change DTU parameters: Support that SMS and information benefit focus adjust DTU parameters.

IO exchanging esteem work: Two channels input, two channels IO yield. Remote control and perusing. Caution status edge, programmed alert flag report work.

Solid correspondence reinforcement work: Support programmed exchanging between principle server and reinforcement server, bolster TCP and UDP programmed switchover (now wear "t have TCP and UDP programmed exchanging capacity). It will associate with reinforcement server when principle server has issue, and will take UDP to correspondence once TCP disconnected.

Solid server programming support, application for a long time, solid capacity.

Bolster unique APN, server farm bolster altered IP and DDNS.

Working temperature go: - 40C-80°C, correspondence is not affected at - 40°C.
