But 20 to 25 would probably be better because the optos in the output chain to get to your laser may good for much more than that. I just had to pull the opto and bypass it on that pin of a cheap 1205 BoB. It was too slow even for a 20 KHz signal. > > ----------------------------- > Regards / Groete > > Marius D.
