Virtual COM Mode

Using Virtual COM Mode, you can use media converter and imagine that the number of COM ports on PC are extended.

This mode is especially useful on controlling the RS-232C/422 devices far away from PC at hand.
Refer to Configuring and Wiring Devices of Virtual COM Mode to connect the computer and serial device.

There are two ways to use media converters on Virtual COM Mode.

- Usage of Virtual COM Port
By following the Install Media Converter, you will be able to access the media converter in the same way as you would access the COM on your computer.

  A virtual COM port is realized by using a virtual COM driver and a virtual COM server together.
  For this reason, the response speed will be slower than that of the PC's main COM.
  Also, some Win32 APIs for serial communication are not supported.

- Usage of Virtual COM Programming
When using it on an OS other than Windows, such as Linux, you can access the media converter using virtual COM programming.
No need to Install Media Converter.

Virtual COM programming uses the F&eIT protocol (Socket function) to create dedicated applications.
Since this access does not use a virtual COM driver or virtual COM server, you can expect faster responses than with a virtual COM port.

Since the access is done in a completely different way than the PC's main COM, applications used with the PC's main COM cannot be used.
