What is the maximum distance of the USB cable that can be used for connecting my computer and a NI USB DAQ device?


The USB specification limits the length of USB cables to to 5 m for high speed data rates.

For distances further than 5 m, NI recommends that you use a DAQ device with an Ethernet bus connector such the cDAQ-9181/5/9 chassis.
