Mike,
Thanks for the reply!
We have about 6 glass scale measuring devices connected using a Mitutoyo DRO-CARD-2 Linear scale acquisition card. It's an ISA card, the only settings on it are where the data is stored in memory. I can access the following locations:
210H to 21FH,230H to 23FH,250H to 25FH,270H to 27FH,290H to 29FH,2B0H to 2BFH,2D0H to 2DHF,2F0H to 2FFH
We've always used 210H, but I have tried all memory locations with no luck.
When I use the AccessHW in and out ports, I can't set the preset value, numbers on the scale bounce all over the place when you extend the device.
We use the in port to read the scale info from the card, and use the out port to set the pre-set value and initialize the card.
It seems like the problem is AccessHW only allows for reading 16 or 8 bits, and when I read using 16 bits, part of the word is being lost, causing the numbers to bounce around.
The only thing I can see using is the In and Out port vi's from Labview 7x in my 6i programs (I know the connectors will need to be changed) if this is at all possible.
Thanks again,
Steve

Steve:
I believe the DRO cards have been discontinued by Mitutoyo. You may want to think of the implications in case the card goes bad and needs replacement.
