The Universe Convert portion of DMXRef is designed to help you out when you have a lighting console with more than one universe of DMX that does not understand addresses with a universe in front of them (i.e. 2/5):

To get the global address of a given local address simply enter the universe and address into the appropriate text fields and press the “Global Address” button.

To get the local address of a given global address simply enter the global address in the “Global:” text field and press the “Local Address” button.

All conversions will be added to the list and saved until you press the “Clear” button.

Still having problems, let me know.
