I'm confused. Have set up a DRDAQ to monitor a column chromatography process and am using the 2 external sensors with adaptors and voltage divider to bring the outputs of the flow and conductivity sensors to 2.5VDC It all works well on my desktop but when I try to set the system up on either of 2 laptops I can't get the bugger to record those 2 external sensors. The pH and voltage (for UV asbsorbance) channels work fine. Have tried using a common settings file between the three but to no avail. Same cable used each time. Any ideas?
Desktop is Windows 2000, the laptops Windows 2000 and 95.
