This is my project beam table that I picked up recently, it came with a pretty cool controller and I slowly plan on trying to add as near all the original functions. The controll would chase the beams originally and used a touch pad for single beams, latch momentary and custom chase. (This was all ttl controlled originally and didn;t come with the touch panels) I Just added a DMX board for control and custom chase also beat chase. It is working pretty nicely and still goes through the main controller as you can see the green LED's indicating beam status.
I need to get one or 2 more 8 channel controls to add more functionality and will be building another beam table as well as this controller was meant for (2) tables (2) gas lasers and full color control and scanners.
