USB Diagnostics

USB Config is a program that allows you to check various operating parameters in the touch screen when it is connected to a computer via a USB cable. This is useful for diagnostic purposes. USB Config is part of the Touch+ Software Suite, which you can download from our Software page.

For the capabilities, latest firmware versions and USB settings for each model, see NextWindow Touch Screens - Latest Technical Information.

	With the 12 VDC power already connected to the touch screen (all models except 1900), connect the USB cable from the computer to the touch screen. The computer then automatically detects the USB device (the touch panel) and, after a short pause, displays a series of messages on screen.
