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. **** (Please do not send a fax as we will not be able to respond to fax inquiries since Microtek fax line is used strictly by other departments such as accounting and administration.) **** Installation: 1.

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 - 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.
