What you do next depends on what your exact setup is. If the scanner is all that you're attaching to the interface, or if you're connecting the scanner to the SCSI port on the back of another external SCSI device already connected to your computer, you can leave the termination the way it is. If you have previously installed a SCSI interface, say, for an internal hard disk, check with its documentation first. You may need to remove the SCSI termination on the card. To change the termination setting on your card, refer to the documentation included.
Some cards use a small jumper block on the face of the card to change the termination.
Still others may require separate software supplied by the card's vendor or even a combination of both techniques. Find out how. 810, the high-tech dream machine.
