Pdf here: http://www.taydaelectronics.com/datasheets/A-258.pdf

LaserRoom software: I think this is compatible with soundcard dac. Website: http://laserroom.org

I dont tested but i think is good for this, because compatible with cm106 sound card.

Cheers!

Hi James!
 
 I made this offset, but its not working.
 I connected offset to usb sound card from DealExtreme.com , i make to X and to Y 0V  and i connected to galvos AL30K "PT30K" (1 to +IN, G to -IN and to GND ) but nothing. I connected to sound card speakers it makes sound if I click to projector on, but galvos dont work. I set sound card to 6channel.
 I use LaserRoom Software and LFI_Player_V1.1.6
 
If I plug a USB to PC ( software not running ) in all outputs in offset i have Voltage. ( If i running software + projector ON , this voltage jumping.) Its good or not? but for the galvos i set 0V.

 What is wrong !?
 Please Help!
 
 Sorry for bad English!
