GPI (General Purpose Interface)
The DM2000’s CONTROL port (25-pin D-sub connector) provides
a GPI (General Purpose Interface). You can configure the GPI so that
it will output 8-channel trigger signals when you operate the faders
or User Defined Keys, or receive 2-channel trigger signals to control
DM2000 parameters.
You can assign any function to these trigger signals. In this way, for example, you can con-
trol a “RECORDING” warning light outside a studio from the DM2000, or you can control
the DM2000’s Talkback function or Dimmer function using an outside switch.
See page 350 for more information on pin assignment.
1Use the DISPLAY ACCESS [SETUP] button to select the GPI Setup page.
2To assign functions to incoming trigger signals, use the cursor buttons to
select INPUT 1 or 2.
3Use the Parameter wheel or INC/DEC buttons to select a parameter, then
press [ENTER].

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.
