Just to give an update to steps I have taken to fix the unrecognized input problem:
Did a fresh install of XP Pro on the same computer by removing the 2000 hard drive and wiping the replacement HD. Installed the Camsoft software from the Camsoft V14.2 CD. I installed NO other software - just XP and Camsoft. After installing the Camsoft drivers for the Galil and Adlink boards, I experienced the same problem.
I decided that maybe it was the PCI bus in the HP, so I "borrowed" my wife's computer, a Dell running XP Pro. This computer has never had any Galil or Adlink software installed. I installed the Camsoft software and hardware. Same problem.
Back to the original computer. I decided that it might somehow be the I/O card. I purchased a new Adlink PCI 7296, installed it, same problem.
I tried a different Opto22 interface board (I have old series optos installed, so I tried a G2 series) and different cabling. Same problem.
Camsoft believes this is a driver problem or a memory conflict problem, and I am working my way to believing it since I have systematically eliminated most of the potential hardware problems. But, why would a fresh install with no other software loaded have a driver/memory problem?
I/O on the Galil board (limit switches) seems to work fine, so this problem is isolated to the Adlink hardware/software. This problem makes most of the machine features useless, since my toolchanger and table indexing routines that all WAITUNTIL will hang.
PLEASE, can anyone think of anything else to try?  |
