New Laser today from Laserwave. need help

[ExideGlow]

have the card form DZ DB-25. And im using mamba black.

when I draw only one blue point, the green will not shut off. the same if I make a green point so blue will not turn off.

and if I make something that's red, the green and blue laser do not want to turn off. but i can adjust the strength.

I have measured the db 25 break out board. and blue + is 7 pin and the - are at pin 19 and for the green + 8 and - at 20 is that right ?

I measure all outputs. with a multimeter. and the USB DAC is sending out 4.5 volts for red green and blue. but I only drawing a green line. should not the blue and red be turned off ?

Hey ExideGlow! Do you have it wired like this:


The color lines should be:
pin 5 - RED
pin 6 - GREEN
pin 7 - BLUE

Do you have the -R, -G and -B lines connected? If so, that tells me that mamba may not have a true ILDA output. If you do have -R, -G and -B lines connected, you might try turning on switches 3,4 and 5. This will send -R, -G and -B to ground.

I have G - and B- connected. but i dont have red laser.

but if i using the multimeter pip functions i find the green + at pin 8 and - at 20

That would make sense if you were counting from the wrong side of the connector. Here's a pinout of a DB-25, are we talking about the same pins/numbers?

yes thats right. but i dont think the db-25 card is the problem. the usb dac is not turn the power off, on R+ and G+ if i only doing a blue point or a blue circle. and same if i make a green circle the blue and red has the same Volt as the green.

Hmm, interesting. Did you make the ilda cable that connects between your DAC and projector? Any changes if you turn on switch 3,4 and 5 on the breakout board?

nope. I bought it. and i do not use it now. and no changes if i turn down the 3.4.5.

i will take a picture

Ok cool, a pic may certainly help! That's wierd, are there settings in mamba to route colors to certain lines?
