Hello,
Measure can interface with a DAQ device, a GPIB device, or a serial port. So if your serial instrument takes standard ASCII commands, you can control it with Measure. There is no CAN interface with Measure.
This information is available from the Measure web support site at www.ni.com/support/meassupp.htm. Please visit this site whenever you have Measure questions in the future.
Have a nice day,
