Laserboy DAC connecting to DMX board

hi everyone!
ive been speaking to james lehman alot, most probably anoying him too much!
but finnaly i have a working LaserBoy DAC and scanpro20s.

but i dont know how to connect the laserboy amo to the scanpro DMX board???

origionally i connected it to the + lead on the scanner amps (wire which come from the standard DMX) to the outputs on the modded soundcard!. but im sure this isnt the propper way to do it. and its bad swaping wires round each time i would like to use sound activated mode!!!!

i need to know ift the laserboy can be connected to the ilda port on the DMX, and what is the pinout.

if anyone has any information or diagrams to share it would be greatly appreciated!

thank you!
Paul Hammond

Forget about anything DMX !!! :eek: This is PURE ILDA ANALOG and a slight verient, at that!

Sorry for the confusion, but welcome to the conversation......

James. :)

yes. but i till have to hook it up, ive heard about someone hooking it up to their ILDA compliant connector

anyone help with the wireing at all!

He is saying, that the scanpro20's have a DMX board, that have ILDA inputs and thru's on them. He wants to know how to hook up the amp to the ILDA connector ;)

Please read this entire thread.

All the clues are here. Use a meter!!! There is no "one answer" that I can give you. It's your projector.

I have tried wiring up my LaserBoy DAC to the ILDA port, But it does not seem to work. How did you connect the LB Dac to your scanner amps?

The Scanner Amp Input has ( "+" / "GND" / "-" ) and i am unsure if you can connect it to "+" & "-" pins or "+" & "GND" ?

prehaps its something to do with the dip switches aswell!
what pinout did u use???

the only way i know to connect it up. is to disconnect the 3 wires from the DMX-AMP, but leave the ground connected! then connect the laserboy outputs to the +wire, let the - wire hang!

I think I'm starting to understand why you are having difficulty. You don't have an ILDA port! :eek:

Please take some pictures of what you have so we can all see it and identify the various parts.

If you can scan any image at all, even with nothing more than the DMX board, then you should have everything you need to hook up the LaserBoy Correction Amp.

Don't ruin anything you have, taking it apart. You will need to measure voltages and stuff coming from the DMX controller to set your correction amp to match.

James, The ScanPro20's come with a controller board that is refered to as a DMX board, It is a basic controller that has Sound-Activate Mode on it, And a few built in Frames for use with DMX, the Board has DMX in/out and ILDA in/out aswell as 3xTTL Laser Outputs. The ILDA in/out have ribbons to DB25 socket/plug. I have wired up mine to the ILDA in, but no look. I have the Laserboy DAC wired to DB25 as ILDA Standard Pinouts.

1 X+
2 Y+
3 Intensity +

5 R+
6 G+
7 B+

14 X-
15 Y-
16 Intensity -

18 R-
19 G-
20 B-
25 Ground

Here's the Manual for the DMX/Program Board --> http://www.lasershowparts.com/files/...NPRO/20KPB.pdf

I think I see the problem. :D

1 X
2 Y
3 Z (not used)

5 R
6 G
7 B

14 GND
15 GND
16 (not used)

18 GND
19 GND
20 GND
25 GND

If this is a true ILDA port then it is also required that you tie pins 4 & 17 together as a safety interlock and you should also have +5VDC on pin 13 to open the shutter.

The LaserBoy Correction Amp is totally single ended. There is nothing differential about its inputs or outputs. All grounds are exactly the same. The +5VDC to open the shutter should come from the +5VDC USB power.

Please look this information up somewhere else and confirm it. My projector is not compliant with this spec!!!

Other than this, have you gone through the LaserBoy Correction Amp trimmer tweaking process? Do you know that this setup will produce an inverted wave?

What pin is used for intesity then ?

R, G, B are all analog voltages from 0 to +5V. That means that at any given time, you can have anything from nothing to full-on red, green and blue, independently. It is the relative mixture of these three colors that gives you the look of all of the colors you (think) you can see.

If you only have one laser and it is TTL, then use the fourth color output of the LaserBoy Correction Amp, (I) to control the level of that one laser. It is a TTL signal that is either high when the laser should be lit or low when it should be blank; an nothing in between.

In the near future I will be releasing a version of LaserBoy that will have a channel assignment matrix and you will be able to assign any signal to any channel and even have more signal types to choose from.

I have one laser and its modulated ?

Well, you can convert your colors to gray scales and send any of the the color channels to your green laser. Or just go with the TTL channel.

James. :)

BTW... I just got portaudio 19 to compile on my Windows machine!!!

Things are looking good as far as getting LaserBoy to be able to talk to the sound system directly. Weeeeeeeeeee!!! :D

Does this mean that laserboy will be able to output directly to the sound bus without having to export waves ?

Eventually, yes. But it also means that it can play waves that have already been made and do stuff to the stream before it gets sent to the sound card.

This came from here:
http://www.laserfx.com/Backstage.LaserFX.com/Standards/ISP-DB25.html

If we reinterpret this information in the context of a single ended, common ground situation like The LaserBoy Correction Amp, then it looks like this:

http://hacylon.case.edu/laser/LaserB...ngle_ended.gif

You can either short pins 4 & 17 together or put an emergency cut off (closed to open) switch between them.

For the average SS RGB projector, the important signals are 1-X, 2-Y, 5-R, 6-G, 7-B, 4=17, 13=+5VDC, 14=15=18=19=20=25=GND.

excellent, That was the same chart i was using from laserfx :D

ps. damn you, i got my linux box back out the cupboard :D
