Hi Folks

I've just part-built a single colour green 1/2 watt projector but in need of input info for this Laser Physics UK Ltd. power supply. The unit has a spare DB9 which is RS232 and a DB15 which has the user interlock. This is marked "J3 Us:er I/F" I guess this is a typo or misprint and should say "J3 User I/F".
I really need this info as I'm not modulating the laser yet as you will see from my videos.

I've got a few videos of my laser operating, one in my showroom (my friends nightclub). I can't operate it there when it's open as it's a little powerful and I need to build some safety features in!

Beam show at Illusions Worthing

Graphics capability without case or modulation

Any help with finding the info on this unit would be greatly appreciated as I'm all googled out!
