Hello,
We are currently running 16 NI-6509 DAQ PCI cards in a SuperLogics computer with a 16-slot PCI backplane running Red Hat Linux. Because 16-slot PCI machines are not common we were wondering if could convert to the USB version of the 6509 and use a more common machine to control them. One of the things these boards do is measure tachometer pulses on rack cooling fans. So each of the 16 boards polls its tachometer every 2 milliseconds. All 16 USB-6509s would have to run from the same computer/hub.
My question is would this work? 16 USB-6509s, all on the same USB hub and each polling their tachometers every 2 milliseconds?
Thank you,
