Troubleshooting
SAW TOUCH PANEL
After verifying that the ELO Touch
Screen driver is installed, verify that
the touch panel is responding to the
host computer.
From the ELO Touch Screen
Program, select the Diagnostic
tab.
If the touch panel is responding, a
check mark will be in the Control-
ler Information box next to the
COM port menu.
If it is not, a red X will appear next
to the COM port menu.
If a red X appears, verify that the
appropriate COM port has been
selected and that the serial cable is
connected to the touchscreen port
of the display unit.
If the COM port matches the
connection of the host computer
and you still get an X when
initialized, then verify that the
serial cable type is a Straight
Connect not Null Modem type.
If all of the above is correct then
there is something wrong with the
touch panel, contact Z
