仕ETH232IW型工業互聯網/串口轉換器實現通過互聯網與RS-232/485/422串口的通信，支持計算機、平板電腦以及智能手機。產品進行了重要的改進:1.採用了新的帶安裝孔的外殼、2.工作範圍溫度達到工業級—40∼+85度、3.內置2500V光電隔離及1000V變壓器隔離、4.支持交叉線/直連線、5.以太網升級到了100M、6.增加了簡化版的虛擬串口軟件。它具有超小型的外形(80*25*55mm)，外插計算機網口或者ADSL貓的LAN口轉換出RS-232/RS-485/422，還可以虛擬成為本地計算機串口，支持串口透明傳輸。波仕ETH232IW是上的工業互聯網/串口轉換器。波仕新一代專利產品,謹防假冒!專利號:201120297328,200630307752。
ETH232IW
工業互聯網/串口轉換器
RS-232/485/422通用、5V供電(5∼24V)
-40∼+85℃
1、硬件安裝
將ETH232IW接上電源（直流5∼24V，隨產品配套有5V電源）。RJ-45插座上有其中一個小LED燈，當產品通電後LED會一直亮著。自動適應交叉線和直連線，LINK燈也亮。
波仕ETH232IW產品的RS-232/485/422串口端是一個DB-9針座，具有RS-232、RS-485、RS-422全部引腳。當作為RS-232口時與PC機的DB-9針RS-232口的2、3、5腳分配完全相同。作為RS-422時，T+、T-是指從ETH232IW產品向外發送、R+、R-是指向產品內接收。注意RS-232/485/422通信時建議要接地線（5腳）。RS-485/422信號的參考地線與RS-232的GND是一樣的。
DB-9針端的引腳分配如下(配有接線端子)：

ETH232IW不僅以太網（RJ-45）與串口之間有變壓器隔離（1000V），而且還增加了一道對串口的2500V光電隔離，實現了以太網（RJ-45）、外接電源、串口（RS-232/485/422）三方的隔離。ETH232IW的串口的高通信速率為115.2Kbps。RS-485口內置有600W抗雷擊浪涌保護器。
