The Microtek MS-PNR Card

Appendix E
The Microtek MS-PNR interface card is an 8-bit ISA SCSI card which uses an
I/O port address setting to communicate with the scanner.
The MS-PNR card works only with Microtek scanners; you cannot connect any
other SCSI devices to it. If you wish to connect multiple devices to one card,
you should purchase an ASPI-compliant card manufactured by companies such
as Adaptec. An ASPI-compliant card is a standard SCSI card that works with
most SCSI devices available in the market today.
The MS-PNR comes in two versions: one with a jumper, and one without any
jumper.
• The version of the MS-PNR card without any jumpers has a label on the back
of the card identifying it as the MS-PNR.
• The version of the MS-PNR card with a jumper on it has the words "MS-PCZ-
2" printed on it, in addition to the label on the back of the card identifying it as
MS-PNR. If this is your card, see the additional Notes below on using the MS-
PCZ-2.
Troubleshooting with the MS-PNR
When you start up your scanner and computer, the Microtek driver
MSPNRI.SYS will try to communicate with the MS-PNR card through ad-
dresses 779 hex and 379 hex (779h or 379h). The driver then tries to set an
alternate address of 280h, 290h, 310h, 320h, 330h, 340h, 248h or 350h to use
after the initial communication is established.
Situations may arise, however, in which you have trouble communicating with
your scanner. If this happens, take note of the following:
• Make sure your card is seated in the computer properly. Sometimes the back
of the card tends to pop out after it is installed and the screw on the card is
tightened. Check to see if this is the case with your MS-PNR card, and make
sure it's seated properly after it's been installed. Push the card back in after
you tighten the screw (or don't tighten the screw too much to prevent the card
from popping out).
• Make sure you have no other card which may be using addresses 379h and
779h. Sometimes, other cards set for 360h can use multiple addresses beyond
the original address number. For example, a card set for 360h could use a
range of 360h to 380h, which will then occupy address 379h and not let the
PNR card work.
