For years I have successfully used the Icron USB Ranger 2204 Cat 5 Extender with both cDAQ and SCXI. But now I have one very annoying issue. I only recently purchased some NI 9237 units for my pressure transucers. Those, and only those, modules don't seem to like being polled over the USB-to-Cat5 extenders which I have in both of my test cells. I have timing issues. Not with all of them all of the time. But with all of them some of the time and with some of them all of the time. I get that pop-up message that says not all of my channels have been read. Increasing the timeout even to ridiculous lengths helps not at all. The rest of the porgram works just fine so long as I do not assign a bridge channel. So, what gives? I can't go bringing my PC closer to the test setup because of safety reasons. We're a combustion lab. I don't want to have to be stringing out long wires all of the time because we're a test lab and those get set up, taken down, changed all around every week. It's a big issue. Can anybody recommend a USB extender other than the Icon which they have used with good success on the 9237 units? All that I am trying to read are finite samples, just two of those, and the speed doesn't matter much. I've already tried different speeds to no avail.
