VO-4 REAR PANEL CONTROLS

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 network switch. The RJ45 connector provides two LEDs that indicate Ethernet link and network activity (see table below).

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 devices
are not interoperable with non-Vocia devices.
