Post subject:  second integrated encoder, I2C_2, will not give info

I am having issues with daisy chaining the VEX Integrated Encoders. The second encoder, I2C_2, is not being read in the Sensor Debug Window. I am only using 2 motors and 2 integrated encoders. The I2C_1 encoder LED is giving a short green flash. It is reading on sensor debug fine. I2C_2 is giving 2 short green flashes. This seems like a correct thing for the last int encoder in the chain to do. However, no readings consistently come into sensor debug. Once, i received some values from I2C_2. Then they stopped. The daisy-chained-4-pin-wire did not seem to be loose. Sensor debug seems to know that I2C_2 exists, but won't send info. Anyone know the solution to this? Solving this seems necessary for auto straightening.

I'm going to refer to the duplicate VEX thread ( for this issue, as there is already a good discussion and progress being made over there. Splitting the conversation into two places will only increase the confusion and redundancy in the debugging process.
