Check group number in the data configuration because if you do not have the same group number you will not receive data either, do you have Ping with the balance?
You have to enter settings and you have several tabs, in one of them you have the group number, I think remember that it is the tab that puts section
Good Javier, a question to discard something, in the dfs you have a tab that you display and you can make a
ping to the scales that you have connected is a kind of tab with a symbol of a connector, when you display the scales appear, and it is very important that all of them turn green, if the one you say does not turn green the problem is not group configuration but wiring or ip, we must first discard that ok.
