Configuring Windows COM Port Settings

Troubleshooting | Compatible Hardware | Hardware Setup Wizard

Some hardware, including physical inventory scanners, PIN pad devices, and serial models of pole display, require assignment of a Windows COM port. The COM port setting for this hardware specified in Point of Sale must match the setting in your Windows Device Manager.

Point of Sale will select a port setting for each piece of equipment, but Windows may assign a different port, depending on other hardware you have installed and the available ports.

Use this procedure to verify or select a COM port in Windows Device Manager and then make the same selection when setting up the hardware in Point of Sale.

To verify or configure Windows COM Port settings:

1. Access the Windows Device Manager.

2. Double-click Ports (COM & LPT).

3. Double-click the entry for the model of hardware you are setting up.

4. Select the Port Settings tab.

5. Select Advanced.

6. Change the COM Port number to the default port assigned by Point of Sale, if it is available.

Note: If the default COM port is in use by another device, an unused COM Port should be selected. In such cases, you will need to change the port setting in Point of Sale to match the port selected here.

7. Click OK.
