Yep, done that many times.

It could also be a bad network cable, the most definitive check is to try a different set of network cables. I would check if all sharing is affected; see if you can view bow transducer data at the console or see bow transducer temp data at the console head unit. We have a very similar setup and sharing is nearly instant.
