ASPI SCSI CARDS
---------------
- 1502E card (Shipped with the latest Microtek scanners)
Microtek now ships the Adaptec 1502E card with most scanners. You can
identify this card by looking at the manufacturer's name (Adaptec) on the
card. This card has jumpers on it that can be set to a number of
I/O and interrupt addresses.
An I/O is a port address. There are two settings available on the 1502E card
which ships with your scanner. They are 140 (default) and 340. By removing or
installing jumper position "ALT" you can configure your card to 140 or 340.
An interrupt, also called an IRQ is the way your computer talks to your
card. You must have both a free I/O address port (140 or 340) as well as
an interrupt (or IRQ) in order for your scanner card to function properly.
The default IRQ setting of your card is 10 but interrupts 9, 11 and 12 are
also available on the card. Before you change the jumper to configure it for
any of these interrupts, make sure you have an available setting you can use.
As mentioned before, the default setting is 10 but by moving the jumper from
10 to 9, 11 or 12, you can change the interrupt to that number. If you have
trouble communicating with your scanner, try changing this jumper to all
possible values before calling technical support.

as accounting and administration.) ****

- Adaptec ASPI cards 2940 and 3940
You can use your existing Adaptec card but you may have to change some
configuration options before you can communicate with your scanner. With
most Adaptec cards, you need to change the SCSI transmission speed to 5 MB per
second. If you do not have a setting for 5, set it to 10 or the lowest
number possible. Also, you need to turn Synchronous Negotiation to
"Disabled" for whatever SCSI ID the scanner is set for.
You can do this by pressing the CTRL-A key combination when you first turn
your computer on and see the message; "Press <CTRL>-<A> for SCSISelect(tm)
Utility".
This is how you access the Adaptec setup program. Then, you can change
different options for your interface card. You only need to change the
above settings for the SCSI ID your scanner is set for. For
example, if you leave the scanner at its default setting, change the Sync.
Negotiation to disabled and the speed to 5 or 10 for SCSI ID 6 only which
is the default SCSI ID the scanner ships at.
