浪涌保護的RS-232至RS-422/RS-485接口轉換器，可以使一個RS-232終端設備與您的RS-422/485網絡相連，它非常適用于PC機、終端設備、工業控制、數字儀表采集、多串口設備、單片機的串行接口等諸多領域。
性能指標：
★ 轉換模式：將RS-232數據轉換為RS422/485
★ 程控信號：無需RTS流控
★ 工作狀態：LED狀態指示燈
★ 信號：RS422:TXD+/-、RXD+/-
★ 信號：RS485:RX+(A)/RX-(B)
★ 傳輸速率：300bps-115200bps
★ 傳輸距離：1.2km
★ 直流電源：DC9V 400mA
★ 隔離電壓：持續隔離1000V;
★ 工作溫度：0-75℃ 濕度≤90%(無冷凝)
★ 外形尺寸：850mm×50mm×25mm
★ 連接頭：RS232接頭為DB9；RS422/485為插入式端子
使用方法:
(1) DB9孔與RS-232設備用軟線連接，DB9孔的2腳是發送，3腳是接收根據連接設備屬性置DTE/DCE開關。(出廠時開關置在DCE端)
(2) RS-422/485側為接線端子形式，包括TX+、TX-、RX+、RX-和電源輸入
(3) 電源應由RS-422/485側統一供電，不能跟RS-232側共地。
