Hi John

First, is this an ISA or a PCI card? I'll assume it's
an ISA card like my two SIIG parallel port cards. If
not, the following advice may not be much help.

Is there just one or is there more than one parallel
port on the card? (If there are four groups of jumper
blocks with two sets of identical looking pins in each
group, the card has two parallel ports.) If there are
two ports, there will be a set of pins (maybe near the
top of the card) to plug in a narrow but long ribbon
cable with a port connector on the end. You might not
still have the cable.

For each parallel port there should be four jumper
blocks (sets of pins for jumpers). One jumper block
will let you pick the IRQ for the port. (It should
have something like the numbers 5, 7, 9, 10, 11, 12
stencilled or etched next to the pins.) Another block
of pins will let you pick the DMA channel used by the
port. (You might see 0, 1, and 3.) On my cards, there
are four pins (two adjacent jumpers needed) for each
DMA channel. You install both jumpers for the DMA
channel that you want to use. Another block would be
used for setting the I/O Port address. (You might see
278, 378, and maybe a few more.) Finally, there would
be a jumper for the Port Mode. (SPP/BPP, ECP/EPP, EPP,
and ECP might be the four choices.)

You could pick IRQ 7 because both parallel ports
can usually use the same IRQ value. Don't use IRQ5
since this is the standard IRQ for sound. If you
need to use an IRQ other than 5 and 7, you may have
to go into your computer's BIOS Setup (at boot time)
and "reserve" this IRQ for use with "ISA or Legacy
device" so that Windows does not try and assign that
IRQ to a PCI device.

You'll have to look in Device Manager to see which
DMA channels are free. Then pick one of the free ones
and set the jumpers. (Remember that this may take a
pair of adjacent jumpers.) If you use SPP/BPP mode
(Standard Parallel Port / BiDirectional Parallel Port)
you don't need to use a DMA (Direct Memory Access)
channel...so you can remove the pair of jumpers or put
them sidewise so they hang off the last pair of pins to
keep them safe. But if you use your scanner on this
card's port, you'll probably want to use ECP and/or EPP...
which requires a DMA channel.

The I/O port address is a likely source for conflicts.
First open Device Manager and highlight Computer. Click
"View devices by resource" and put a dot in "I/O address".
You must now find which I/O Port address is free. Values
will be in hexidecimal (1,2,3,4,5,6,7,8.9.A.B,C,D,E,F,0
instead of 1,2,3,4,5,6,7,8,9,0.) Remember that you
require 8 consecutive free bits in memory. Set the jumper
on the card for a free address.

When you install the Parallel Port card, you may have to
use "Add new hardware" in Control Pannel and add an LPT
port.

If Windows does not assign the exact same resources to
the new port in Device Manager as the values you set by
jumper, things won't work. (Your ISA card is not Plug
and Play.) You'll have to uncheck "use automatic settings"
and choose a different "Basic configuration" from the drop
down menu. Even after this, you might have to highlight
"Input/Output Range" and click on "Change setting". If the
message "This resource cannot be modified" appears, select
another "Basic Configuration" and click "Change Setting"
again. Repeat this until the "Edit Input/Output Range"
dialog box appears. Type in the value that you set by
jumper. Now go back and check that your IRQ is still set
correctly. Repeat all steps if it changed. Reboot when it
looks like you have the correct values assigned. After
rebooting, you may find that you have to start all over.
However, things will work eventually.

If you need to contact SIIG by phone, their number is
(510) 353-7542 or email them at [log in to unmask]
The serial number of your card is J02H60054585 and the
part number is JJ-A21012. This is not the same part
number as either card that I have...but it's similar.
Their website lists different names for their ISA cards
than the ones that I have.

Bill
