Using GPI (General Purpose Interface) 259 Using GPI (General Purpose Interface) The DM1000's CONTROL port provides a GPI (General Purpose Interface) for controlling external equipment. You can configure the GPI so that it will output 8-channel trigger signals when you operate the faders or USER DEFINED KEYS, or so that it will receive 4-channel trigger signals to control the DM1000 parameters. You can assign functions to these trigger signals. In this way, for example, you can control a "RECORDING" warning light outside a studio from the DM1000, or you can control the DM1000's Talkback function or Dimmer function using an outside switch. 1 14 2 15 3 16 4 17 5 18 6 19 7 20 8 21 9 22 10 23 11 24 12 25 13 This is an example of the external circuit that operates GPI. In this example, a trigger signal causes the LEDs to light up when the button is selected as the trigger signal polarity in the OUTPUT section. A trigger signal causes the LEDs to turn off when the button is selected as the trigger signal polarity.
