GPRS DTU作為一種通信設(shè)備，其應(yīng)用場合十分廣（guang）泛。在不同的應(yīng)用中，數(shù)據(jù)中心的IP地址及端口號，串口的波特率等都是不同的。因此，GPRS DTU都應(yīng)支持參數(shù)配置，并且將配置好的參數(shù)保存內(nèi)部的長久存儲器件內(nèi)（一般為FLASH或EEPROM 等）。一旦上電，就自動按照設(shè)置好的參數(shù)進(jìn)行工作。 GPRS DTU的擴展功能：較為專業(yè)的GPRS DTU還提供一些擴展功能，主要包括：支持?jǐn)?shù)據(jù)中心域名解析 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

DTU在制定方案中的作用及其**功能我們在制定無線數(shù)據(jù)工業(yè)監(jiān)控采集傳輸方案時，需要了解GPRS DTU的**功能，才能制定出基于通信網(wǎng)絡(luò)的GPRS DTU方案。下面介紹四種功能： 1）內(nèi)部集成TCP/IP協(xié)議棧 GPRS DTU內(nèi)部封裝了PPP撥號協(xié)議以及TCP/IP協(xié)議棧并且具有嵌入式操作系統(tǒng)，從硬件上，它可看作是嵌入式PC與無線GPRS MODEM的結(jié)合；它具備GPRS撥號上網(wǎng)以及TCP/IP數(shù)據(jù)通信的功能。 2）提供串口數(shù)據(jù)雙向轉(zhuǎn)換功能 GPRS DTU提供了串行通信接口，包括RS232,RS485,RS422等都屬于常用的串行通信方式，而且GPRS DTU在設(shè)計上大都將串口數(shù)據(jù)設(shè)計成“透明轉(zhuǎn)換”的方式，也就是說GPRS DTU可以將串口上的原始數(shù)據(jù)轉(zhuǎn)換成TCP/IP數(shù)據(jù)包進(jìn)行傳送，而不需要改變原有的數(shù)據(jù)通信內(nèi)容。因此，GPRS DTU可以和各種使用串口通信的用戶設(shè)備進(jìn)行連接，而且不需要對用戶設(shè)備作改動。廣西GPRS-dtu外殼價格</p><p
