DMX-USB interface

Hello

I would like to connect and control my RGB LED light by PC, so I will need DMX-USB interface like your K8062.
But I can’t understand is it possible to use stand alone mode with K8062 or I need to have it connected to my PC at all times?
Could you recommend me another DMX-USB interface with stand-alone mode?

I hope to find the answer here. Thanks.

K8062 must be connected to a PC at all times.
No stand-alone unit in our range.

Thank you for information, VEL417.
