About GPI
GPI is an abbreviation for General Purpose Interface. Using GPI input and output, DMEs can be
remotely controlled from custom-made controllers or external equipment. The number of GPI ports
depends on the type of device. Sets GPI input/output for each DME.
Using GPI input data, you can switch DME scenes and change component change component
parameters.
Refer to the DME owner’s manual for information on making GPI connections and other hardware-
related issues.
GPI Input/Output Setup Example
■ Control Faders (Levels and On) via a CP4SF
A CP4SF control panel connected to the GPI terminal can be used to control the faders (Level and On
parameters) of Fader and Mixer components.
By assigning the component's Level and On parameters via the Parameter Value Edit function in the
GPI IN field it becomes possible to use the CP4SF faders and switches to control the assigned Level
and On parameters. If the port assigned to the Level parameter is set to [Min]=-INFINITYdB,
[Max]=10.00dB, [Terminal]=
, the parameter will be controlled in proportion to the input voltage (=
fader position). The minimum input voltage will produce a level setting of - ∞dB, and the maximum
input voltage will produce a level setting of 10.00dB. If the port assigned to the On parameter is set to
[Min]=OFF, [Max]=ON, [Terminal]=
, the parameter will toggle between ON and OFF each time the
input voltage goes from low to high (= the moment that the switch is pressed).
By assigning the component's On parameter via the Parameter Value Edit function in the GPI OUT
field, the CP4SF switch LED can be toggled by the ON parameter. If [Terminal] is set to
, a high level
will be output when the On parameter is on, lighting the LED.

Only users for whom the [Operation Security] → [Edit] checkbox has been checked can make GPI settings.
