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.
1. Start the Device Manager.
[Device Manager] can be started from the menu displayed by
right-clicking the Windows mark (start button) at the bottom of the Windows
screen.
Ex) with COM-4CX-USB
Ex) with COM-1(USB)H
2. Confirm if the recognized USB device is displayed in the [Universal Serial Bus controller] folder.
3. 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.
1. Display the properties of the device you want to change in the [Ports (COM & LPT)] folder.
2. Select the [Port Settings] tab in the properties window and click the [Advanced...] button.
Ex) with COM-4CX-USB
3. You can change the COM port number in the [COM Port Number] combo box in the [Advanced Settings for COM] window.
Ex) with COM-4CX-USB
Supplement :
By checking [Compulsion Half-Duplex], the software setting
can be forcibly switched from full-duplex communication to half-duplex
communication.
Ex) with COM-1(USB)H
