What controls DAC speed?
When I send a smaller ILDA image to my REKE 500RGB through the iShow DAC, it draws pretty well. If it has 200 points, I can see it draws pretty fast. So fast, I cannot count the revolutions.
But, when I send the ILDA Test Image, containing over 1000 points, it draws it like two times a second. Really slow. I am not talking about scanner speed, or how much error there may be in my slowish scanners. I am referring to the DAC’s ability to pump the signals into the ReKe. I just don’t get it.
I suspect that my system is too slow, or the DAC is too slow. But I am really uncertain. I am driving my scanners at 12K, and I expect to see some error and I do.
The system: Windows XP, iShow, iShow DAC, ReKe 500RGB.
I'll try to take some video and see if I can demonstrate what I'm talking about. Also, sending DWGs to the ReKe from iShow is really fast, although if I over drive my scanners, there is considerable error. But there is no perceived slowness in sending the signals to the ReKe.
