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.
1 Use the DISPLAY ACCESS [SETUP] button to select the GPI Setup page.
2 To assign functions to incoming trigger signals, use the cursor buttons to
select INPUT 1 or 2.
3 Use 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.
