DMX and Contact Closures

Miranda can control 300 fixtures per unit, spread across two DMX universes of output.  A fixture can be a single-parameter dimmer or a multi-parameter LED fixture with emitters.
What counts as a fixture? A dimmer is a one-parameter fixture, an RGB LED is a three-parameter fixture, and an RGBW is a four-parameter fixture.  Each fixture counts towards your 300-fixture limit, regardless of how many parameters it has.
Miranda has Phoenix connectors for DMX, as well as contact closure inputs. 
Contact closures are input triggers assignable to cues.

DMX

DMX connections are labeled on the outside of the case: Data +, Data - and Common.

Contact Closures

  • 1 thru 4 are contact closure inputs
  • 5 is Common for 1 thru 4
All contact closures appear in the Triggers Tab to assign to cues.  The closure is triggered by connecting the contact closure input to common.

Switch

This is a three-way switch:
  • Roll the switch away from the phoenix connectors for contact 6
  • Press the switch for contact 7
  • Roll the switch towards the Phoenix connectors for contact 8
💡
As the switch is a local control, this is intended to be utilized to initiate a test sequence during troubleshooting.
