R-8554A GPRS DTU

R- 8554A GPRS DTU GPRS無(wú)線(xiàn)數(shù)傳模塊

主要特點(diǎn)

- 采用RS-232/ RS-485接口，用戶(hù)可實(shí)現(xiàn)基于GPRS網(wǎng)絡(luò)的數(shù)據(jù)監(jiān)控；
- 端子可插拔，導(dǎo)軌安裝；
- 產(chǎn)品體積小巧，既可以作為嵌入式使用，也可以外置使用；
- 支持透明/協(xié)議數(shù)據(jù)傳輸，內(nèi)置軟硬件看門(mén)狗，電磁兼容設(shè)計(jì)
- 支持短信、本地串口和遠(yuǎn)程中心端DTU圖形界面參數(shù)維護(hù)；
- 支持中英文短信接收、單發(fā)、群發(fā)功能；
- 支持?jǐn)?shù)據(jù)中心端固定IP地址訪(fǎng)問(wèn)、域名解析及虛擬數(shù)據(jù)專(zhuān)用網(wǎng)；
- 有點(diǎn)對(duì)點(diǎn)、點(diǎn)對(duì)多點(diǎn)、中心對(duì)多點(diǎn)、數(shù)據(jù)/短信觸發(fā)、網(wǎng)絡(luò)與短信通道切換等多種工作模式可選；
- 支持中心端實(shí)際串口/虛擬串口對(duì)DTU的一對(duì)一、一對(duì)多通訊；
- 供電電源適應(yīng)范圍寬，提高設(shè)備的穩(wěn)定性；
- 預(yù)留7個(gè)GPIO接口可根據(jù)用戶(hù)的特殊需求定制模擬量、數(shù)字量采集功能的工作模式。
