  • Figure out the COM port number (if using a virtual serial port, look in Device Manager to find the port # assigned).
  • Run PuTTY.
  • Switch the Connection Type to Serial.
  • Edit the Serial Line to match the COM port you want to use.
  • Edit the Speed to match the BAUD Rate you want to use. (Typically 9600)
  • Select the Serial category from the menu on the left.
  • Make sure all of the settings are correct.
  • Select the Open button to start the session.

Scan a barcode, the barcode should be displayed in the PuTTY terminal.

 

Troubleshooting

 If using a USB connected device OR a “Serial to USB” converter.

1) If using a converter: verify that the converter’s drivers are installed.

2) Verify that the device’s USB to COM driver is installed.
