Chapter 3 — Installing the scanner for the PC 32
Connecting the scanner
Before you connect the scanner to your PC, make sure that your scanner as well
as your PC are switched off.
A SCSI cable is supplied with your scanner.
❖ Note: If the cable does not fit, contact your dealer.
Caution: For safety reasons, never use extension cables for power cables.
Always make sure there are no more than two terminators in your SCSI chain, one at the
beginning and one at the end. Some SCSI devices, such as an external hard disk, have
built-in terminators and must therefore be placed at the end of your SCSI chain. Please
check the documentation of each of your SCSI devices if you are not sure whether the
device has a built-in terminator. The last device in your chain has to be terminated. Your
SnapScan has no built-in terminator. For more information about SCSI devices see
earlier in this chapter:
SCSI devices
Never try to connect the scanner to the serial or parallel port of your PC: you might
seriously damage your equipment if you do.
1. Your PC has a 25 pin connector
If your SnapScan is the only SCSI device to be connected to your computer:
1. Switch off your scanner and disconnect the power cord.
2. Switch off your computer and disconnect the power cord.
3. Connect the smaller 25-pin end of the SCSI cable to the connector on your
computer.
4. Connect the larger 50-pin end of the SCSI cable to the connector on your
scanner.
You have to put a terminator between the connector of your scanner and the
SCSI cable as shown on the picture.
