Chapter 20—Other Functions
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 sig-
nals when you operate the faders or USER DEFINED KEYS, or so that it will receive 4-chan-
nel 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.
