Only the last expansion 3HC board
-
Only the last 3HC has both jumpers, the one in the middle doesn't. The middle one will not sync and will not communicate. I was able to upgrade via the SBC all are now 3.2.2. I was able to upgrade the firmware on the middle 3HC by making it the last in the chain then it synched however the one that was last and got put in the middle lost its connection would not sync. The CAN # are different in all and the last one in the chain has the jumpers whereas the middle one doesn't. I put everything back. This is different from the previous post I've seen on this issue the problem doesn't follow the same board, but it's always the one in the middle with no communication. I verified the cables and they are all straight thru here's a pic of the cables

@jsinicro, those are crossed cables. If you put the ends side by side and the same way up, then for a straight cable the colours should be in the same order as here.
.
If you put the connectors end to end as in your picture, then for a straight cable the colours would be in the opposite order.

@jsinicro Figured it out was the cable that was not straight thru, I was looking at it the wrong way.

Thanks, I'll mark this as solved.
