If the touchscreen is not responding to touch, check your
serial or USB connection by doing the following:
❏
❏
A–4
Serial Connection - Run the comdump diagnostic utility
to determine if the touchscreen, the serial touch
controller, the computer's serial COM port and the
associated cabling are connected and functioning
properly. Download the latest version of comdump.exe
(7K) from the Elo Web site Driver and Files Download
page. You should save the file where it can be accessed
easily - either to a floppy or to the root of your hard drive.
Comdump is a DOS application, so if you are running
one of the Windows operating systems you must either
boot to a DOS boot diskette or disable the driver so you
can access the COM port from a command prompt.
USB Connection - If the Human Interface Device (HID)
is not listed in Device Manager after a USB touchmonitor
is connected, check to determine if a file named
mouhid.sys is in the \windows (or winnt)
\system32\drivers folder.
◆
The file will be missing if a USB mouse has never
been connected to the system.
◆
If the file is not there, connect a USB mouse to the
system or copy mouhid.sys from another system.
◆
Once mouhid.sys is in the proper location, remove
and reinstall the touch drivers.
