MX-4 DV USER GUIDE

CHAPTER 13

USING A GPI DEVICE

You can connect a GPI (General Purpose Interface) device to the MX-4 DV. The GPI device can trigger an event from an external source, such as a push-button switch or an edit controller with GPI output. A GPI device is especially useful when you are positioned some distance away from the MX-4 DV but still want to be able to control its operation.

A GPI pulse causes the MX-4 DV to behave exactly as if the play button were pressed. Normally, it starts a transition you previously set up. If you are playing back a Learned sequence (refer to Chapter 11, Learn Mode), it triggers the next event in the sequence.

An edit controller or computer that provides a contact closure can also serve as a GPI triggering device.

WARNING

Do not connect a power source of any kind to the Control GPI input connector on the MX-4 DV. Doing so can damage the equipment and void your warranty.

You can use a remote push-button device to trigger events on the MX-4 DV. If you already have a GPI device you want to use, refer to “Live Broadcast Configuration” on page 38 to learn how to connect the device. If you do not have a GPI device but would like to build one, refer to the instructions in the next section.
