Hi Alex, Maybe this question shall be addressed to someone else but as a continuation to the major topic, I will try to ask it here. So I got the NI-8452 device. I have successfully managed to communicate with ADS1118 - So I know the NI-8452 is functional. When I'm trying to communicate the ADS1293 , the SDO line remains low although the rest of the lines look fine (at least timing and voltage-wise). See image: The SDO line here is even not loaded by the MISO line of NI-8452 (just to verify that there is no "drive" issue). Per the ADS1293 DS, the SDI line is being sampled on rising edge for 8 first clocks. Meanwhile the SDO line is in tri-state. Starting from the falling edge of the 8th clock, the SDO line shall become driven by ADS1293 - And it's not happening. Could you please assist? Thanks in advance, Oleg
