Hello - I am trying to use NI USB 6361 to control a CMOS device with digital inputs 0.8V to 2.4V logic thresholds, but cannot find any place to set the output digital signal from NI 6361. Anyone knows?
Thanks,
Pem

The Digital IO is TTL only. You'll need to use a level shifter circuit to convert to CMOS.
