OM-CONV-SER歐米茄RS-485到RS-232接口轉(zhuǎn)換器OMEGA

將RS-232數(shù)據(jù)傳輸（TXD）和數(shù)據(jù)接收（RXD）轉(zhuǎn)換為平衡半雙工RS-485

從RS-232端口供電

數(shù)據(jù)速率高達115200 bps

點對多點，***多可連接32個RS-485設(shè)備

OM-CONV-SER是***個RS-485半雙工到RS-232轉(zhuǎn)換器。它由計算機的串行（COM）端口供電，因此不需要外部電源。該裝置體積小，傳輸距離長，能處理高數(shù)據(jù)率，性能穩(wěn)定，連接到標準DB9串行（COM）端口。該轉(zhuǎn)換器可廣泛應(yīng)用于工業(yè)自動化控制和測量系統(tǒng)以及PLC應(yīng)用。

OM-CONV-SER歐米茄RS-485到RS-232接口轉(zhuǎn)換器OMEGA

Converts RS-232 Data Transmit (TXD) and Data Receive (RXD) Into Balanced Half-Duplex RS-485

Powered From RS-232 Port

Data Rates Up to 115,200 BPS

Point to Multi-Point, Up to 32 RS-485 Devices Can Be Connected

The OM-CONV-SER is an RS-485 half-duplex to RS-232 converter. It is powered from the computer’s serial (COM) port so no external power is required. This unit is small in size, has a long transmission distance, can handle high data rates, is very stable in performance and connects to a standard DB9 serial (COM) port. The converter can be used in a wide range of applications including industrial automatic control and measuring systems and PLC applications.
