thanks John, i'll remember that!

Actually the 7I43 will drive 4 7I29 cards (or 2 7I29s and a 7I37). Even though the 7I29 uses a full 50- pin I/O connector. it only connects to 12 of the 24 signals on the cable, and has an option jumper to select whether it connects to the channel 0/1 or 2/3 signals. This means that 2 7I29s (4 Axis)can connect to a single FPGA card connector. The smaller 7I40 bridge has the same feature.

Cool Ty PCW for clarifying. This board is full of great experience with these systems. For Newbs like me trying to work their way to an end result.

Thanks, i have read that, but wasn't sure of clear understanding.
so a configuration like one 7i43, two 7i29s and a 7i37 would be perfect. maybe just to begin i'll prefer the 7i40 that you suggest (money..)

a question: for a further enhancement, will it be possible having this configuration, change the two 7i29 with 4 3phase 8i20?

i know emc support for 8i20 is still in a dev-phase, but in the future i wish is going to work..
what about emc2 and the other mentioned cards?

thanks, Davide.

Support for the 8I20 is still beta but the 7I43 can support 6 8I20s via the 7I52 6 channel com / 6 channel encoder daughtercard or even a 7I47 daugtercard (4 channels) though the serial channel pinout is sort of awkward on the 7I47.
