How long is your cable? I mean total length from cRIO to sidecar plus from sidecar to accelerometer. Our cable to the accelerometer is quite short, maybe that is the difference? I know I2C is designed to work over very short distances, it is more often used on the same circuit board or across a backplane. There are dedicated I2C drivers that work well over a couple meter long cable but more often the driver is really just some sort of logic port on a FPGA or a I2C peripheral and not as strong as the I2C spec recommends.

I'll measure it tonight, and create a short cable to check. Thanks for the help.
