Confirm and Change COM Port (Media Converter)

When a device (hardware) is installed on a computer, a COM port is automatically assigned. (COM1, COM2, etc.)
General-purpose package software (application software) uses this COM port to perform serial communication.

 

Confirm COM port

1. Start the Device Manager.

2. Confirm if the added COM port is displayed in the [Ports (COM & LPT)] folder.

　Depending on the environment, COM ports may not be assigned sequentially starting from CH1 on the device.
　Therefore, check which CH number on the device corresponds to which COM port, and then specify the COM port on the general-purpose package software.

　

 

Change COM port

You can also change the COM port number from Device Manager.

1. Display the properties of the device you want to change in the [Ports (COM & LPT)] folder.

2. In the Properties window, Select [Port Settings] tab.

　You can change the COM port number in the [Port Number:] combo box in the [Serial Port Settings] frame.
　Configure the settings as required and select [OK].
　

3．Restart the virtual COM server.
　　The settings in the "Port Settings" tab will not be reflected unless you restart the virtual COM server.
