Fig. 2-3 The device name listed on the Device Manager

Note:

✎

If your card is properly installed, you should see the

device name

of your

card listed on the

Device Manager

tab.

If you do see your device name

listed on it but marked with an exclamation sign “!”, it means your

card has not been correctly installed.

In this case, remove the card

device from the

Device Manager

by selecting its device name and press

the

Remove

button. Then go through the driver installation process

again.

After your card is properly installed on your system, you can now

configure your device using the

PCI-1784 Utility

program that has itself

already been installed on your system during driver setup. A complete

device installation procedure should include

board selection

and

device

setup

. After that, you can operate this card through the

operation

. The

following sections will guide you through the

board selection

,

device

setup

and

operation

of your device.
