Using GPI (General Purpose Interface)

The rear panel GPI (General Purpose Interface) connector can be used as an input/output
connector. This connector provides five GPI IN ports and five GPI OUT ports. For example
you can use an external switch to control internal parameters of the CL series console or to
switch scenes. Conversely, operations or scene changes performed on the CL series console
can send control signals to an external device.
For details on how to send control signals to an external device when you switch scenes, refer
"Outputting a control signal to an external device in tandem with scene recall (GPI
to
(page 98).
Using GPI IN
You can use the GPI IN ports of the GPI connector to control the parameters of the CL series
console from an external device. For example, you could use an external switch to turn the CL
series console's Talkback on/off, operate the Tap Tempo function, or switch scenes.
STEP
1. Connect an external device to the CL series console's GPI connector.
2. In the Function Access Area, press the SETUP button.
3. In the SETUP screen, press the MIDI/GPI button.
4. In the MIDI/GPI screen, press the GPI tab.
5. Specify the POLARITY MODE for each port as appropriate for the specifications of
