Quick overview

ILDA lasers are previous generation laser systems, using an older control methodology based on analog signals that communicate to an XY scanning laser projector, via a piece of laser control hardware. This was the original laser show setup, and dates back several decades. It’s currently being phased out, as easier and more efficient setup configurations take its place (such as FB4). 

An ILDA laser is a type of laser projector that uses a DB-25 connection to carry its signal for control.
