How to configure spaghetti with sound card dac?

[ElektroFreak]

you're using either vista 64 or win7 64 right? The newer 64-bit OSes won't take unsigned drivers at all. To use unsigned drivers you need either winXP or a 32bit version of Vista or Win7..

If you tell Gary you're uninstalling your original Spaghetti install, he'll give you another license for a different computer. You can only have one license active at a time..

Ok I got the driver to work on the 64-bit PC. I made a wav in laserboy and tried again. Same as last time, nothing happened. Maybe it has something to do with the projector itself?

Here is a picture on the setup:

Did you build the board or did 300EVIL? Also, does the projector have a switch to go from DMX to PC control? If so, it might be on the rear panel..

Another thing to look at is the orientation of the op-amps. If they're backwards obviously things won't work quite right..

300EVIL built and tuned the board.

From the projector manual:

When the ILDA interface connected to exterior console, light will automatic change to exterior control mode, and needn't to convert switch.

But as I've said, nothing happens when I plug in the ILDA cable, the mode doesn't even change (still sound active)

For future reference, can you share how you got the driver to work in 64 bit win 7?

[300EVIL]

Ah! Could be that the projector needs to see the interlock loop to switch form DMX to ILDA. This was the case on Aidan's projector with my board. In this case, throw a jumper between point "4" and "GND" on the AUDIOLASE board. I'm pretty sure this is your problem.

Like this...

I used a version hosted on your site, this one I think: http://hacylon.case.edu/laser/EzAudDac/Cmedia_USB/
It appears that driver had a signature.

@300EVIL: Ah sweet! I'll try that tomorrow. thanks.

Well it didn't work.. But I found something else: I don't know much about DB25 cables ,but I tried measuring continuity in the cable, and it turns out NONE of the pins were connected, except one pair, nr 25. That means the cable's broken right?

Lots of serial cables I have worked with before are NOT "pass through" cables, IE some cross over, some loop back etc.

For example PIN1 may go to PIN3 the other side, or pins 1 and 2 maybe be looped and not even go to the other end.

Make sure you have / get a cable that goes 1-1, 2-2, 3-3 etc.

Also as Adam said, I’m interfacing with my DMX player board, I had to short pins 4 and 17 to make the player board switch to ILDA input.

I’m using HE-Laser scan, also try LFI Player if you struggle with HE-LS. just for testing.

Ok, I got a new cable and it actually fixed something. The projector now changes to ILDA mode when I plug in the cable, but there is still no output. One time I plugged it in there was a single green dot not moving, but that was when I wasn't even playing any shows. .

As you can see in this picture I'm not measuring anything on the points going to the DB25 cable, except one: the "misc out" has varying voltage like one would expect from the other channels..

I'm so tired of this.. I just want it to work..
