Re: Question about Hardware IO mapping

Hi Dusko,
I really understand the "if it ain't broken, dont fix it" cliche, but
unfortunately the old server was on its last leg so it needed to be replaced,
that's why we were having to relocate everything. The company is a fuel oil
dealer, and the cards are used to import tank data from each of the trucks
into the fuel program that they are using. In the morning the trucks go out
with a card in them and all of the data pertaining to the fuel sales/delivery
is recorded, and in the evening the office takes each of the cards and
imports the data into the fuel program on the app server. LC stands for
Liquid Controls.
You have interested me in the mapping of the onboard parallel port being
mapped to that IO address. This might be the answer to our issue, as are
your other advices. I moved everything (hardware and software) that was in
the old server and worked in conjunction with the LC card reader. I was told
the ever famous "its very important".... which translates to "we're too lazy
to write out the tickets by hand." Nonetheless, I am stuck with this
non-working fixture that I need to get working.
You ask if it can be replaced by something more modern? Oh sure, but then
that would involve changing out the trucks as well, which in the end means
the company is going to have to update alot more than they're willing to
shell out for. The original drivers and software for the system came of
floppy disk if that tells you anything. We have another client who is
running the same software package but they get their info via wireless
transmission, so yea, there's other ways to skin the cat but it all comes
down to the overall price and being scared of change.
I'll certainly let you know what happens as soon as I address it tomorrow.
Thanks for the tips!!

Hi dtremain,.
There's an old saying, "If it ain't broken, don't fix it".
Anyway, I remember good old days of "daisy chaninig" parallel ports.
First, you would attach a scanner, then you would daisy chain IOMega zip
drive and finally, you would daisy chain a printer.
Frankly, I don't know what LCRAM card reader is. Can it be replaced by
something more modern? USB card reader perhaps? What sort of data is being
exported/imported?
First
You may try to "SET LCBASE=10c0" by an alternative way, ie System
Properties/Advanced/Environment Variables. Set this variable as both System
variable and User variable (under user account that starts your
application).
Second
Why does it have to be PCI-DIO24 ?
On some motherboards, the built-in parallel port can be remapped to 380h.
Good luck, and please keep us posted. I'm dying of curiosity.

I am in need of some direction with I/O mapping. We recently moved a.
client
from a 2000 server up to a new 2008 server. In the old server was
PCI-DIO24
parallel interface card that was linked to an LCRAM card reader which was
used by an office app to import and export data. The old IO address of
the
card (in the 2000 server) was 380h, and on that 2000 server everything
seemed
to work fine. When I moved the apps and hardware from the old server to
the
new one the application that drives the LC cards is still wanting to read
based on the old hardware address, 380h, even though the new address is
10c0h. Is there anything I can do within the server's autoexec files to
correct (or manipulate) the address of the card so the cards can be read?
When I attempt to run the app it says that it cannot find an I/O card at
address 380h. I have uninstalled and reinstalled the drivers thinking
that
something might change, but no luck yet. Our programmer found the old
manuals and they stated to use "SET LCBASE=10c0" in the autoexec.bat file
and
that would cure the issue, but doing so has not resulted in anything
positive, and to be honest I thought that the newer platforms do not use
autoexec.bat anyhow so I didn't expect it to work. Can anyone give me so
pointers?
Thanks in advance.
