I am in need of some serious help. I purchased a scanner set off Ebay, model PT-20K that included the PT-ITRUST showcard. I tried this setup out with a green laser pointer I had. I decided to go the next step and purchased a RGB laser module. It didn't come with any instructions what so ever. The only info on it is W200-12V-130114006. I know the unit is 12 volts and worked fine when I powered it up. When I connected it to the showcard to modulate the lasers I fried the circuit board on top of it. I think it's the driver card for the lasers so I think it can be replaced. My main question is how do I connect this laser unit to the showcard for modulation. Does anyone have/know of any documentation for this laser. It's from China and I have emailed them but there is no info about it. I plan to buy another one but I don't want to burn it up too. Also, what can anyone tell me about the dip switches on the showcard? I will try to include photos of my project as it stands. It's just the test phase so don't be too hard on me. Thanks very much.
