Connect DC Remote In

grandMA3 User Manual » First Steps » Connect DC Remote In
Version 2.3

To use the DC Remote In with grandMA3 consoles, onPC command wings, and I/O Nodes connect a contact closure switch, for example, a light barrier or a push button.

For further information, see the topics Remote keyword, Remote In and Out, and Output configuration.

Up to 64 input channels can be used within a session.

Hint:
It is possible to move faders analog, for example, the Master Fader by using a grandMA3 console or I/O Node connected with a potentiometer (0 to +10V DC).
The onPC products can switch on and off, but do not fade.
  • Generate a switch or connect an external source that sends up to +10V DC to pin 1 for the console to react to analog input number 1.
  • The recommended resistance is 5 kohms to 10 kohms.
  • To use the DC Remote, feed a voltage signal (maximum +10V DC) into the corresponding input pin. For more information see the pinout image below.

To connect a switch:

  • Take +10V DC voltage in pin 5 for the grandMA3 console or I/O Node

-or-

  • +5V DC voltage for grandMA3 onPC command wing and command wing XT

-or-

  • Take an external voltage source (+10V DC in grandMA3 consoles or I/O Nodes and +5V DC in grandMA3 onPC command wing and command wing XT), connect its ground to the common ground pin of the device.  Connect the +10V DC voltage source to one input pin 1-4 or 6-8 with a potential-free contact (switch, buzzer, motion detector, or any other switching device) in between.

Circuit examples:

  • Potentiometer +10V DC in grandMA3 consoles or I/O Nodes
Potentiometer +10V DC
  • Switch +10 DC in grandMA3 consoles or I/O Nodes
Switch +10V DC
  • Switch +5V DC in grandMA3 onPC command wing and command wing XT
Switch +5V DC
Important:
Pin layout in grandMA3 consoles or I/O Nodes:
The grandMA3 consoles or I/O Nodes have a 9-pin D-sub, enabling 7 remote inputs:
Pin 1-4 = input channels 1, 2, 3, 4
Pin 5 = +10V DC grandMA3 consoles or I/O Nodes/+5V DC grandMA3 onPC command wing and command wing XT
Pin 6-8 = input channels 5, 6, 7
Pin 9 = common ground
  • Connect a D-sub plug to the DC Remote In connector on the rear panel.

DC Remote In control is connected.
