Pathport Manager 1


     Create a “NEW” Custom Universe. I called this one ShowOverArch, meaning my Show Console’s source will win over my Architectural controller. Use either the table editor which works much like any spreadsheet or the command line. For example, type:

1-512*1.1-/2.1-

This sets every output slot of your new custom universe (1 thru 512) to accept a priority 1 input from stock universe 1 (i.e., 1.1 - 1.512), which comes from our lighting console in the booth. It also sets, as a priority 2, all of universe 2, from our architectural controller. The / symbol prioritizes the inputs. Inputs listed first, i.e. further left on the command line, are given higher priority. SAVE this custom universe.

Then choose the DMX Patch tab from the top of Pathport Manager and find your output port. In this case, I’m selecting Port A on Robert’s 1012.

    Custom universes are shown at the top of the list when you choose New Univ. Select the Custom Universe you just saved. Touch SEND PATCHES TO PORTS to upload the new prioritized merge of Univ1 and Univ2 to that output port.

Now, when the show console is outputting on Univ1, its level will win. When that console is turned off, the output will get its levels from the architectural controller, which is outputting on Univ2. Now, to ensure the levels don’t ‘slam’ when changing between the sources, select the Node Properties tab in Pathport Manager.
 
      
Pathport Manager - 3


        Select the appropriate Gateway (in this case Robert’s 1012) and then select the port using the Custom Universe (in this case Port 1 - Port A) and make sure ‘Crossfade Enable’ is checked. Change the Crossfade Time too if you want. The default is 5 seconds. When done, don’t forget to SEND CONFIG TO NODES.

Now, when a higher priority source comes on line, the levels will change to the new source over 5 seconds. If a driving source goes off line, the levels will fade rather than slam to the new values as well.

p.s. When two sources have the same priority, the output level will be the highest of the two (HTP). This makes sense with intensities, but for attributes of moving lights, such as Pan, ‘highest’ is meaningless and you really need to figure out which source should win when active and give it a higher priority.
