Troubleshoot

If Control Panel / Devices and Printers displays USB Serial Device instead of Vx805 PIN Pad, the following steps should help.

  1. Unplug terminal, uninstall driver from Add or Remove Programs, and reboot.
  2. Then plug in terminal device.
  3. Open Devices and Printers and look for USB Serial Device (COM#) and record which com port it says it is using.
  4. Then (while terminal is plugged in) install the driver from our setup tool, and select that same port number.
  5. Then reboot, and confirm it displays as Vx805 PIN Pad (COM#).
