ANSI E1.31 standards use a 16-bit field for universes allowing for 65,535 total universes with a range limited from 1 to 63,999 (0 and 64,000-65,535 are reserved). Currently the DMX Chop will only output data if the universe parameter is 32,767 or lower.
Seems like it might be using a signed int for the variable rather than an unsigned int.

Are you testing via loopback from DMX Out CHOP → DMX In CHOP within the same TouchDesigner file, or are you sending to another system/device?
Could you share an example file?
I took a look into it and indeed it’s mistakenly clamping to the Art-Net max number of universes (32768) rather than the sACN max – I will fix this. Thanks for the report.
This will be fixed in the next official build we release: 2025.32600+.
