Resetting the Address of the Scanner
If SCSI address #5 is in the list of SCSI addresses in use, then you must reset the
SCSI address selector to another number:
1.
Ensure the scanner power is off.
2.
Choose any unused number in the range 0-6.
Note: Do not use settings 7 to F on your scanner. They are for factory use only.
3.
Reset the scanner’s SCSI address to the number you have chosen.
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.
PowerLook 3000 has a built-in terminator switch for you to turn on and off (see
the illustration). Number 1 represents “active” and number 2 represents
“terminator power”. 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 turn on the “active” and “terminator power” switch by pressing them
down to enable the built-in active terminator function. 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, turn
on the terminator switch. 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.
