商品名称: MVI46-MCM防雷转换器
商品型号: MVI46-MCM
基本参数:MVI46-MCM串口防雷转换器
商品介绍:
MVI46-MCM是一款有源防雷型RS-232到RS-485/422的转换器(又称防雷RS-485转换器、防雷RS-422转换器,RS-485/422卡),是深圳市六合华杰科技有限公司为了处理RS-232串口设备与RS485/422串口设备之间的数据通信而专业方案的,它可以将单端的RS-232信号转换为平衡差分的RS-485或RS-422信号,内置的操控芯片可以主动辨认RS-485或RS-422信号,无需人工调拨。其另一大特点是内置的防雷管极点有效的克制了雷电和地电位差对设备带来的损害。具有很强的防雷防浪涌功用。该转换器可供给点到点,点到多点的联接。点到多点联接时可联接32个RS-485/RS-422设备。是用户在户外做体系工程的佳选择!
>>商品特性:
1. 主动发送/接纳数据,无需外部的流量操控信号(RTS)
2. 可以联接32个RS-485或RS-422接口设备
3. 电源及双色数据流量指示灯,可查看缺点点
4. 异步半双工(RS-485)或异步全双工(RS-422)通用,无需跳线设置
5. RS-485/422供给每线600W的防雷维护和避免共地烦扰
6. 适用于全部所运用的通讯软件,随插即用
7. 支持DOS/WIN95/WIN98/WIN2000/NT/XP Linux等
