I'm touching the touch panel, so why do I get no respons?

1) Call the Inepro Helpdesk, it could be one of these problems:

a) Check CMOS settings, COM3 needs to be “Enabled”. The correct settings

are “3E8h” and “IRQ10”.

b) Check that there are no conflicts between COM3 IRQ10 and any other

devices.

c) Check that the ELO driver has been properly installed. Or try to re-install

again (Please refer to the ELO driver installation).

d) Check that the ELO controller on COM3 has been detected during the ELO

driver installation. If yes, than check that the flat cable from the ELO touch

screen has been properly connected to the ELO controller (Attention: Pin1

mark should be on the same side as the ELO controller).

e) Check that the ELO controller Green LED is blinking?

i) If no, there is no DC+5V support for the ELO controller from the

mainboard. Check the mainboard JP10 jumper settings.
