Hi 1der,




Use a serial port for serial communication. Or use a DAQ device capable of analogue input to read voltage signals...

Best regards,
CLAD expired, using LV2011SP1 + LV2017 (+LV2019 sometimes) on Win7+cRIO
Kudos are welcome Smiley Wink

(268 Views) p2: Input high voltage 2.0 V minimum, 5.8 V maximum So, your 7V can works unstable (and can be dangerous for DAQ) If you want to try, see examples fot digital continuous unput.
