Troubleshoot
If Control Panel / Devices and Printers displays USB Serial Device instead of Vx805 PIN Pad, the following steps should help.
- Unplug terminal, uninstall driver from Add or Remove Programs, and reboot.
- Then plug in terminal device.
- Open Devices and Printers and look for USB Serial Device (COM#) and record which com port it says it is using.
- Then (while terminal is plugged in) install the driver from our setup tool, and select that same port number.
- Then reboot, and confirm it displays as Vx805 PIN Pad (COM#).
