</div>### Laser In Touchdesigner Ilda through Helios DAC

Helios is a Digital to Analog Converter for laser projectors.   
This the converter we use @ the Blackbox JK with the **Laserworld CS-1000RGB [(manual)](https://reserveren.hku.nl/resource/document/65e451b0-a4be-4816-90b3-9c17d85b52e2 "manual CS-1000RGB")  
  
Hardware Setup:**

Connect the remote interlock   
Enter the key (watch out, it fits two ways, but only turns if entered correctly. It turns EASILY so <span style="text-decoration: underline;">DO NOT FORCE IT &amp; BREAK THE KEY</span>!!)

To have the Laser listen to ILDA, set the DIpSwitch to everything off :
