*chokes* umm. If you're implying that they selected the 9403 because of the 7us update as opposed to in spite of it then that's disappointing. Considering they were obviously planning from the start to use the IFI Victor speed controllers, and that a 7us update rate combined with the 1ms variation for the Victors yields an astounding 143 counts of resolution.... Well if they were planning on purposefully making the Victors annoying to use and less reliable, then mission accomplished, I suppose. I was assuming that the trade-off was to gain 32 DIOs in a compact form at the price of poor resolution with the Victor controllers.
