Setup: Connecting the SCSI Cable

✔SCSI Connection Checklist

• Turn off the computer, the LS-30, and all SCSI devices

before connecting the scanner.

• Be sure that the devices at both ends of the SCSI chain are

terminated. If the host computer is a Macintosh, the chain

will already be terminated at the computer end. In the case

of IBM PC/AT compatibles in a chain which contains external

devices only, the chain should be terminated at the SCSI

board. In the case of a chain which includes internal devices,

you may need to remove termination from the board and

terminate the last internal device.

• The maximum number of SCSI devices that can be con-

nected in a single chain is eight, including the computer and

any internal SCSI devices such as hard disks or CD-ROM

drives.

• The total length of cabling in the SCSI chain should be no

more than six meters (twenty feet). The longer the cabling,

the less reliable the connection.

• When using a SCSI extension board with an IBM PC/AT

compatible computer, be sure that you have the latest

available driver software for your board. If you experience

trouble with SCSI connections, contact the manufacturer to

learn whether an updated driver has been released.

Setting the SCSI ID

Each device in the SCSI chain has a unique ID, which is a num-

ber between zero and seven that the computer uses to distin-

guish between different devices. When connecting the LS-30

to a SCSI chain, the scanner’s SCSI ID must be set to a number

that is not shared by any of the other devices, including the

computer itself.

The scanner’s SCSI ID is indicated by the SCSI ID dial on the

rear panel. Before the scanner leaves the factory, the ID is set

to “2.”

SCSI ID

When choosing

another ID for the scanner, bear in mind that

the computer will usually have an ID of either “0” or “7,” and

that internal hard disks often have IDs of “0” or “1.” In the case

of Macintosh computers, the computer will have an ID of “7,”

while the internal hard disk and CD-ROM drive often have IDs

of “0” and “3,” respectively. In general, it is recommended that

you set the scanner’s ID to any number other than zero, one,

three, and seven that is not used by another SCSI device.

✔Caution: Assigning the same ID to two different devices

could render the computer system inoperable or result in important

data on a hard disk being lost or corrupted.
