If the [AUX] switch is pressed twice, the lamp of the switch will light up red.

While the lamp is lighted up red, control exercised from an external source can be canceled.

If the same switch is pressed twice again while its lamp is still lighted up red, the lamp is extinguished, and the control exercised from an external source is re‑established.

6-2. GPI connector

This enables auto take operations to be executed by an external device. Auto transitions are executed at the fall of the GPI signals.

The signals are input using contacts. The auto take operations are executed using these contacts as triggers.

Use an M3.5 stereo plug for connection with the main unit.
