Error 200077 occurred at DAQMX Reference Trigger (Analog Edge).vi when using mioDAQ

Updated May 6, 2026

Issue Details

I am getting an error -200077 when trying to configure the Analog Reference for a mioDAQ device. 

Solution

This error is commonly encountered when using mioDAQ devices with versions of NI‑DAQmx released prior to 2025 Q1. Earlier versions of NI‑DAQmx do not support analog triggering for these devices, which can result in configuration or runtime errors.

To resolve this issue, upgrade to NI‑DAQmx 2025 Q1 or later, where analog trigger support for mioDAQ devices was introduced.
