If the scanner is in the middle of a chain, turn the switch OFF.

Setting the Select Switch

The scanner has two SCSI connectors: one for a 68-pin SCSI cable and the other for a 50-pin SCSI cable. You may need to change the select switch setting depending on the SCSI card and cable you are using in your computer.

If you are using a 50-pin host adapter and SCSI cable connection anywhere on the bus between the host adapter and the scanner, use the N setting. Use the W setting for 68-pin SCSI ultra-wide host adapter and cable connections.
