Media converters are products that convert the RS-232C serial communication interface to wired LAN and wireless LAN.
If you use a media converter, you can eliminate cable length restrictions from communication application design elements.Media converters are widely used in remote monitoring systems that use computers and in integrated communication systems of RS-232C legacy communication devices and LAN-compatible devices.
Connect the media converter to a Windows computer with a LAN cable (or wireless LAN) and COM ports can be used as the computer's COM ports. Remote devices can be communicated with in the same manner as a serial cable connection.
The RS-232C cable length is defined as 15 m max. in the standard.To resolve cable length restrictions and situations where laying out the cable is difficult...
You are not bound by cable length restrictions, the device can be freely wired using a LAN cable.With wireless LAN, you can also communicate with mobile objects.
Communications using an existing serial cable connection can be replaced as is with communications using a LAN (or wireless LAN) connection.
If you want to increase the transmission distance, but the only communication method that can be used is RS-232C, the settings on the communication device cannot be changed, you do not want to change the communication software, or wireless communication would be better...

RS-232Cでは伝送距離が短い、伝送速度が遅いなどの欠点を改良してできた規格です。「EIA-422A」とも呼ばれます。各信号線の目的やタイミングは規定されていますが、接続コネクタの規定はありません。多くの対応製品では、D-SUB 25ピンまたはD-SUB 9ピンが主に採用されています。
