Sorry Ether, we took it all apart before we was able to test for 4X. Maybe tomorrow.
However here are the videos from tonight's test.

The key summaries here are the following:
1. We took the encoder out of the gear box and spun it with our fingers to eliminate any questions with the gear box, or shaft slipping. Just the encoder all by itself.
2. When we wired one of the encoders direct to the robo-rio, like Mr. Anderson suggested, this WORKS!!!
3. Not shown in the videos...we swapped out a brand new Talon SRX, made sure the firmware was 1.4, updated the CAN BUS IDs, then tried again. Still missing counts.
4. I got an email from Omar who suggested maybe the small ribbon cable to be replaced, we tried that, and that did not work.
The Grayhill connected to the Robo-rio, we setup at 1X decoding, so the count was exactly 128 and 0. Right on the money as per the video above.
Maybe we are doing something wrong in the software setup? We are using labview. If anyone might be willing to share a working software setup with Talon SRX in closed loop, digital encoder mode, please let me know.
In Omar's email he was testing with a E4P encoder, so we just happen to have one of those laying around. We had an E4P-360CPR. The results are pretty much the same for that one as well, missing counts.
We are completely baffled at this point and getting pretty sick to our stomach, other than we made the call tonight to code a home brew PID loop to get us by for now, we are now 4 days behind troubleshooting software issues. We gotta keep moving.
