If no longer available from NI, would anyone have the (upper) rear connector pinout for the SCXI-2400 so I can make my own cable using half of a DB-25 parallel printer cable and the appropriate AMP connector?
I'm not sure which of the two connectors is the upper one, but there are two connections. One of them uses an RS-232 cable connection and the other is just a 4 wire RS-485 terminal block connector. The latter of the two has a pinout shown here in this article. Here is another useful article that addresses setting up your chassis. I hope this helps.
