212 Chapter 11-GPI Interface About the GPI Interface The GPI (General Purpose Interface) allows remote interaction between DME32 functions and custom-made controllers and other equipment. The DME32 features 16 GPI inputs and 16 GPI outputs. GPI inputs can be used to recall scenes and configurations or adjust component parameters. They can also be configured for use with Emergency mode, in which the DME32 mutes all outputs. The DME32 can be configured to switch a GPI output when a GPI input is triggered, or to transmit a Program Change message when a scene or configuration is recalled via a GPI input, or to transmit a Control Change message when a component parameter is adjusted via a GPI input. GPI outputs can be used to trigger other equipment when scenes are recalled or component parameters are adjusted from DME Manager, front panel controls, GPI inputs, or by using MIDI Program Changes and Control Changes. GPI outputs can be configured so that they switch between high and low when a parameter is adjusted above or below a specified threshold. In a multiple-unit system, all GPI interfaces can be used, providing a maximum of 64 GPI inputs and 64 GPI outputs with four DME32s. GPI Connectors The GPI connectors are 16-pin Euro-block sockets, which mate with 16-pin Euro-block plugs. 16 15 14 13 12 11 10 9 IN +V The top connector contains the IN terminals for GPI inputs 9 16 15 14 13 12 11 10 9 OUT GND through 16 and +V terminals.

External controllers and other equipment can easily be attached to the GPI interface by using Euro-block plugs. Simply insert the bare wire into the relevant hole and tighten the adjacent screw. To prevent interference, use shielded cable and attach the shield to a GND terminal. DME32-Owner's Manual

About the GPI Interface

The GPI (General Purpose Interface) allows remote interaction between DME32 func-

tions and custom-made controllers and other equipment. The DME32 features 16 GPI

inputs and 16 GPI outputs.

GPI inputs can be used to recall scenes and con

ﬁ

gurations or adjust component param-

eters. They can also be con

ﬁ

gured for use with Emergency mode, in which the DME32

mutes all outputs. The DME32 can be con

ﬁ

gured to switch a GPI output when a GPI

input is triggered, or to transmit a Program Change message when a scene or con

ﬁ

gu-

ration is recalled via a GPI input, or to transmit a Control Change message when a com-

ponent parameter is adjusted via a GPI input.

GPI outputs can be used to trigger other equipment when scenes are recalled or com-

ponent parameters are adjusted from DME Manager, front panel controls, GPI inputs,

or by using MIDI Program Changes and Control Changes. GPI outputs can be con

ﬁ

ured so that they switch between high and low when a parameter is adjusted above or

below a speci

ﬁ

ed threshold.

In a multiple-unit system, all GPI interfaces can be used, providing a maximum of 64

GPI inputs and 64 GPI outputs with four DME32s.

GPI Connectors

The GPI connectors are 16-pin

Euro-block sockets, which mate

with 16-pin Euro-block plugs.

The top connector contains the

IN terminals for GPI inputs 9

through 16 and +V terminals.

The second connector contains

the OUT terminals for GPI out-

puts 9 through 16 and GND

terminals.

The third connector contains

the IN terminals for GPI inputs

1 through 8 and +V terminals.

The bottom connector contains

the OUT terminals for GPI out-

puts 1 through 8 and GND ter-

minals.

The open terminal voltage of each +V terminal is 15 V and the maximum supply cur-

rent available from each terminal is 6 mA.

External controllers and other equipment can easily be attached to the GPI interface by

using Euro-block plugs. Simply insert the bare wire into the relevant hole and tighten

the adjacent screw. To prevent interference, use shielded cable and attach the shield to

a GND terminal.
