LTC works in this console

Hello, I have acquired an nx touch for my studio with the console, I would like to know if the LTC works with a specific audio card since I have a focusrite and when I send the LTC signal the clock does not start to work.

try to use midi- or artnet timecode.

What would I need to do that? The timecode is generated on another laptop where the musical playback is generated. the idea is to use an audio channel that reaches the console and executes the cues.

LTC input requires the NX Sync. ONYX does not read the actual audio feed, it requires hardware to decode it.
