Question

Hey guys.

I have a question.
If I use USB Audio DAC + Amp mod Laserboy Correction, I use the TTL circuit of the laser module (image), or connect directly to the module?




Best Regards.
Juanma.

Sorry for my expression, I'm from Spain and I use a language translator.
I want to know if I have to connect the modules directly to the Laser Boy card, or have to use the TTL circuit. And connect it to the card.

Help please.
Thank you.

If I understand correcty, you need to hook the modulation from the DAC to the TTL input of the diode driver. I don't know anything about the dac you are using.

You will need to set the modulation setting in your software to TTL (Transistor-Transistor Logic) rather than analogue.

<edit>If you have a colour correction board, as far as I understand it, I do not think this will work with TTL laser modules.</edit>

You will have to connect to the driverboard in the picture. I beleve all the connections are described on the backside of the plastic-cover of the driver. I is marked with TTL and it is also omportent to notice the + - (positive/neagive) polarization for all cables. Do not trust the plugs/cable as there is no standard for this on chineese equipment. From what i can see in the picture, it is a chineese module (probable a blue) with no tec-cooling. Only a 12V output for the cooling fan, input for 12V power, Input for the TTL and output for the laser diode.

The Blue potentiometer is for adjusting the output current of the LD- (Laser Diode).

Hello friends.
Thanks for the replies.
I will not explain properly, sorry. My question is if I use (DAC) sound card + card Laser Boy (image), we must also use Chinese module circuit, or is not necessary.




Thank you very much.
