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.
PowerLook 2100XL has a built-in active terminator switch for you to turn on and off (see the
illustration). Number 1 represents “active terminator” and number 2 represents “terminator
power”. Turning both the “active terminator” and “terminator power” switch on by pressing them
down will enable the built-in “active terminator” function.
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. Turn on the “active terminator” 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.
The simplest configurations for using the scanner with a SCSI card are as follows:
Case 1: Connect the scanner to an interface card that does not have another SCSI device attached
to it. e.g. Scanner is the only SCSI device connected to your computer.
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 turning on the active terminator of your scanner.
