am having some data issues with Ratpac PDB 12’s. Are there channel assignments that go with the built in 8 Chanel Opto-splitter? Not all of my channels (1-12) are receiving information, and the panic mode must be applied to control those fixtures. Suggestions?
The "Address" is the first NON-DIM Circuit of the 12 on the PDB 12. This allows you too ON/OFF a rigged head that is acting up. So, if your address is "101" and you don't have 101 thru 112 at FL at the console, then you won't have HOT POWER on the channels you are missing.
So the starting address of my first fixture should be 13? Leaving the space of 12 for the PDB unit?
That could work. The Address should be unique like any other light/fogger/whatever and the PDB "12" uses 12 addresses. Maybe you are misunderstanding what a PDB is used for? It is basically a fancy opto splitter with 12 HOT circuits that you can turn ON/OFF at the console. Call RatPac for more info--they have good customer service. (They also make a PDB 10 which is not addressable and does not have the ON/OFF feature.)
