Table of Contents
This article provides an overview of the rear panel of the OMNI 16e and 32e Expanders.

Each Expander includes a power supply connection and dual redundant Dante and HControl ports.

USB connections are located on the rear panel of the Expanders. These ports currently have no functionality and are intended only for service and repair technicians.

Pressing the Locate button causes the LEDs on the front of the Expander to flash. The Expander also flashes in AVX Manager, and pressing this button can be used to trigger logic sequences and events.

Orange connections are designated for outputs.

Blue connections can be configured as either inputs or outputs.

Each input and output can be individually configured as analog or digital in AVX Architect.
