blown parallel port

[sa1]

hey guys,
is there any way of repairing a blown p/port.
from what i read, the port is built in the mother board.
for some reason the port is not functioning at all.
I setup up MACH3 on another PC and it works fine.
I suspect reverse current flow (24v) caused it to blow.
If it cannot be repaired, can I install a seperate p/port card in one of the empty slots?

My PC: P111 1.2gig , 80gigHD , 512RAM

The parallel port is built into one of the support chips for the CPU and as such may or may not be repairable depending on what chip it is, whether it is socketed or soldered down and, if the latter, whether you can get a repair done locally.

You can add a PCI parallel port card and tell Windows and Mach3 to use it instead.

How did you determine the port is not working? Is it all port pins or just one or two? If the latter, it might be that a reconfiguration can still make it useable.

Before addressing the repair, you need to consider carefully what went wrong and what you can do to avoid it happening again. This is why an opto-isolated break-out board is a crucial part of any install IMHO.

thanks irving2008,

I figure i connected the 220v AC to the driver card by mistake, which in fact was supposed to be connected to my cooling fans.
I have had the card repaired, and it works fine with MACH3, because i tested it on another two PC's.
Everything on my PC is working fine beside the p/port.
I do have available slots on the pc.

If I do buy a seperate p/port card and install it, how do I set it up in CMOS to tell Windows to find it?

All you have to do in the cmos is tell the computer not to use the built in pport. Set it to disabled.
When you install the new card it will come with a driver disk and all will be well. Make sure you get a breakout board before you install the new pport.
Make sure you use the adress of the new card in Mach3 as it may or may not be different than the old pport address. Also seach the zone for a list of pport cards that work well with Mach3. Not all cards will work.

Thanks irving2008,

i will check around which card is most applicable.

Thanks TOTALLYRC,

Will get a breakout board first, before trying out the new pport.
