What are other possibilities for this problem away from battrey and fiberoptic cable ? i mean any hardware board could cause this problem ?
Of course it could be the cpu in the head or console. 95% of the loss of communication is from a low battery or weak fiber. Did you shine the red led light in the optics to make sure one side isn’t brighter than the other side. I have found This to be the issue multiple times on intermittent issues, cut off the bad side and put a new connector on and the issues disappear.
