Checking the Terminators
There should be two terminators in a SCSI chain: it is best to place the terminators at
each end of the SCSI chain.
The simplest configurations for using the scanner with an ASPI compatible SCSI
card are as follows:
•
Connect the scanner to an ASPI compatible interface card that does not have
another device attached to it.
In this situation, the card will have a built-in terminator. The card forms one end
of the SCSI chain; the scanner forms the other end. Simply attach the supplied
external terminator to the scanner. These will ensure that there are two
terminators and that they are placed at the ends of the SCSI chain.
•
Connect the scanner to an ASPI card that has another device attached to it.
In this case, check to see if the other SCSI device has a terminator. If not, attach
the terminator to the scanner. If the other device has an internal terminator,
simply attach the scanner to the SCSI chain. Although the terminators are not,
technically speaking, placed at the ends of the chain, the scanner should work
properly.
If you experience unreliable SCSI operation and suspect terminator problems, or
would like a more thorough discussion of SCSI terminators and possible problems
with SCSI terminators, please consult your dealer.
Connecting the Computer and Scanner
Now that the interface card has been installed and all of the settings on the scanner
and card are properly set, you can connect the computer and the scanner. Once this
has been done, the hardware installation will be complete. To connect the scanner
and computer, do the following:
1.
Connect the SCSI cable to the interface card.
2.
If your SCSI configuration requires the use of the terminator, turn on the
terminator switch.
3.
Connect the other end of the SCSI cable to the scanner.
4.
Connect the power cord to the scanner.
5.
Turn on the scanner power.
