VO-4 Hardware

This section is provided to aid in the use of the Vocia Output 4 (VO-4).  Please see the VO-4 Manual for further information on installation of the device.

Power Indicator LED

On the left of the front panel, the VI-6 has a single LED that indicates power and connectivity status:

  1. Not illuminated: The device is not powered.

  2. Flashing green: The unit is receiving power but not data, or the unit has not been configured correctly.

  3. Solid green: The unit is operational, has been configured and is receiving PoE.

Signal LEDs

Four LEDs located in the center of the front panel act as audio signal identifiers for the four output channels and are useful for setting optimum signal levels. Each LED has four states. Detailed metering of current output levels can be obtained in real time via the Vocia software interface.

The LED illuminates when the output channel is configured and passing audio

Control LEDs

The control LEDs signal the current state of the control I/Os. The first four are input status indicators, and the second four are output status indicators.

Yellow Green Dark
Relays are energized input threshold Not active

Network Connection

The VO-4 has one RJ45 connector located on the rear panel that utilizes standard Ethernet cabling to interface the VO-4 to the Vocia system via a managed switch.  The RJ45 provides two LEDs that indicate Ethernet link and network activity.

Left LED Right LED Description
None None No power or data connectivity.  Please check the Device power and  network connection.
Amber Flashing Green Link established and CobraNet activity detected; the unit is acting as a CobraNet performer (normal operation).
Flashing Amber Flashing Green Link established and CobraNet activity detected; the unit is operating as a CobraNet conductor (normal operation).
Flashing Amber None CobraNet fault. Check cabling and configuration for errors.

Control Outputs

The Control Outputs, labeled 1 through 4, are isolated, voltage-free, software-configurable relay outputs. The individual pins are labeled as follows:

  1. (C): the common/ground pin

  2. (NC): normally closed (connected to C when relay is not energized)

  3. (NO): normally open (connected to C when relay is energized)

Control Inputs

The Control Inputs are labeled as follows:

  1. (Ground): logic common/ground input pin

  2. (1–4): individual logic inputs

  3. (10V): 10V reference voltage (when used as a switch input, a switch must be connected between the input and logic common terminal)

Audio Outputs

Four plug-in barrier strip connectors provide analog audio signal output. The Vocia software enables a nominal output level of +4 dBu, 0 dBu or -10 dBu to support a wide range of connection devices. All plug-in barrier strip connectors should be wired from left to right as follows:

  1. (+) High

  2. (–) Low

  3. Ground
