ER-102 displays SynC no response

#1

Upgraded 101 and 102 to most recent version. 102 is just frozen with “sy” displayed in part screen and “nc” displayed in group screen.

Is this normal?

Not normal. The sync message means the two modules are unable to communicate. Please check the connection between the ER-101 and the ER-102.

Thanks Brian, changed ribbon cable and they are talking now.

When you have a chance, I would mark that cable clearly so that you never connect it to power.
