LPT Question

Post by Scotty » Sat Mar 08, 2008 4:59 pm

Hi All,

I have a question. I have used 4 different computers with the MSA

and had no problems. I just hooked up a 5th computer and encountered

an LPT port problem. It seems the computer does not have pull-up

resistors on the Status Lines, pins-10,11,12,13, and 15. This caused

a failure in reading the AtoD converter, which has an open collector

output.

Computer gurus: Is there a way to "tell" the computer to internally

connect "pull-ups"?

I can change the hardware design to add pull-ups to the AtoD but

would prefer not to.

Scotty
