仕ETH232IW型工业互联网/串口转换器实现通过互联网与RS-232/485/422串口的通信，支持计算机、平板电脑以及智能手机。产品进行了重要的改进:1.采用了新的带安装孔的外壳、2.工作范围温度达到工业级—40～+85度、3.内置2500V光电隔离及1000V变压器隔离、4.支持交叉线/直连线、5.以太网升级到了100M、6.增加了简化版的虚拟串口软件。它具有超小型的外形(80*25*55mm)，外插计算机网口或者ADSL猫的LAN口转换出RS-232/RS-485/422，还可以虚拟成为本地计算机串口，支持串口透明传输。波仕ETH232IW是上的工业互联网/串口转换器。波仕新一代专利产品,谨防假冒!专利号:201120297328,200630307752。

ETH232IW

工业互联网/串口转换器

RS-232/485/422通用、5V供电(5～24V)

-40～+85℃

1、硬件安装

将ETH232IW接上电源（直流5～24V，随产品配套有5V电源）。RJ-45插座上有其中一个小LED灯，当产品通电后LED会一直亮着。自动适应交叉线和直连线，LINK灯也亮。

波仕ETH232IW产品的RS-232/485/422串口端是一个DB-9针座，具有RS-232、RS-485、RS-422全部引脚。当作为RS-232口时与PC机的DB-9针RS-232口的2、3、5脚分配完全相同。作为RS-422时，T+、T-是指从ETH232IW产品向外发送、R+、R-是指向产品内接收。注意RS-232/485/422通信时建议要接地线（5脚）。RS-485/422信号的参考地线与RS-232的GND是一样的。

ETH232IW不仅以太网（RJ-45）与串口之间有变压器隔离（1000V），而且还增加了一道对串口的2500V光电隔离，实现了以太网（RJ-45）、外接电源、串口（RS-232/485/422）三方的隔离。ETH232IW的串口的高通信速率为115.2Kbps。RS-485口内置有600W抗雷击浪涌保护器。
