Setting the I/O Address

The scanner interface card has switches for changing the I/O address. Inspect the card closely and see what the current I/O address is.You can use the recommended I/O address 2AB unless you have a device that uses the same I/O address.

Most conflicts occur when there are several devices/cards such as modems, fax cards, mouse cards, etc. installed in your computer. It is important that you know the settings used by each device so you could assign an unused settings for the scanner interface card. In some cases, it may be necessary for you to change the I/O address settings of device to accomdate the scanner interface card.
