Setup and Use
The Vocia software provides an intuitive interface for conguration, DSP equalization, and programming of the VO-4. The information supplied
by this manual relates to physical connections and assignment. For more details on software setup, please consult the Vocia Help File.
1. Power Indicator LED 2. Signal LEDs 3. Control LEDs
1. Power Indicator LED
On the left of the front panel, the VO-4 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 congured correctly.
3. Solid green: The unit is operational, has been congured and is receiving PoE.
2. Signal LEDs
Four LEDs located in the center of the front panel act as audio signal identiers for the four input channels and are useful for setting optimum signal
levels. Each LED has four states. Please see the table below for the signal mapping to each of the LEDs. Detailed metering of current output levels can be obtained in real time via the Vocia software interface.
Red Yellow Green Dark
Signal above clip threshold > -3dBFS
3. Control LEDs
The control LEDs signal the current state of the control I/Os. The rst four are input status indicators, and the second four are output status indica­tors. They have three states:
Signal above nominal but below clip threshold > -18dBFS < -3dBFS
Signal above minimum but below nominal threshold > -48dBFS < -18dBFS
Signal below minimum threshold < -48dBFS
Yellow Green Dark
Relays are energized > input threshold Not active

Network Connection
The VO-4 has one RJ45 connector that should be wired to standard copper Ethernet cabling to interface the VO-4 to a Vocia system via a PoE-compliant network switch. The RJ45 connector has two LEDs that indicate Ethernet link and network activity (see table below).
Left LED Right LED Description
None None No power or data connectivity. Please check the PoE network connection.
None Green Link established.

Device ID
The rotary ID switches are located on the back of the VO-4 and give the unit a unique Device ID. The switches are in hexadecimal format. All VO-4 units must have a unique Device ID to function properly within a Vocia Paging World (i.e., it is not possible to have two VO-4 units with the same Device ID of hex 07). To assign a Device ID of hex 07, turn the LSB switch to 7 and leave the MSB switch on 0. To create an ID of hex B7, turn the LSB switch to 7 and turn the MSB switch to B. Device ID switches should be set using a 0.1 inch (2.5mm) to 0.12 inch (3.0mm) flat blade screwdriver. More information on setting IDs and the hexadecimal numbering scheme used in Vocia can be found in the Vocia Help File.
Please note: Changes made to the Device ID while connected to the network require a power cycle in order to take effect.
CobraNet
The VO-4 is a CobraNet device. All CobraNet routing and bundle assignments are processed by the Vocia devices locally. Vocia makes dynamic use of available bundles in CobraNet. Vocia devices are currently not interoperable with non-Vocia devices.

This connection carries control data, power, and digital audio over CobraNet. The maximum distance between any unit and an Ethernet
switch is 328 feet (100 meters) when using copper cabling. Additional Ethernet switches and/or ber-optic cable can be used to further
extend distances between units on a network. Please note that CobraNet limits network extensions to seven hops (one-way transmissions) within a network.
If other network trafc shares an Ethernet switch with the Vocia network, a managed switch should be used with separate VLANs. All Ethernet wiring is to be done using shielded CAT5, CAT5e, CAT6, or CAT7 cable.

VO-4 REAR PANEL CONTROLS
Control Outputs
The Control Outputs, labeled 1 through 4, are isolated, voltage-free, software-congurable 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. ( ): 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 Inputs
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
Ground Screw
This screw provides a connection point to ground the chassis of the VO-4. The power supply to the VO-4 is sourced from PoE, which may have no connection to ground. The chassis of the VO-4 should be connected to a safety ground (main power supply ground) using the Ground Screw

VO-4 INSTALLATION
Installation
The VO-4 requires one 1.75 inches (44.45mm) high and 19 inches (483mm) wide rack space with 10 inches (254mm) depth. Mounting the unit using four screws with washers will prevent marring of the front panel. PVC or nylon washers are appropriate.
Please install the unit away from heat sources, such as vents and radiators, and in rooms with adequate ventilation. Ensure that air can circulate freely behind, beside, and above the unit. Do not exceed the maximum ambient operating temperature of 113 degrees F (45°C). Be aware of conditions in an enclosed rack that may cause the temperature to exceed ambient room conditions.
