Aux Port
A RJ-45 connector is available internally for use with Biamp accessories. This port is not an Ethernet port
and must not be connected to a
switch, PoE supply, or other Ethernet network devices.
Network Connections
PoE-enabled network switches or PoE midspan adapters must be used to power the unit. These must be
802.3at Type 1 compliant. The maximum cable distance between any unit and an Ethernet switch is 328
feet (100 meters) when using copper cabling. Additional Ethernet switches and/or fiber-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 100Mb network. If other network traffic shares
an Ethernet switch with the Vocia network, a managed switch should be used with separate VLANs.
The connector provides two LEDs that indicate Ethernet link and network activity.

Device ID
The rotary ID switches give the unit a unique Device ID. The switches are in hexadecimal format. All units
of the same device type must have a unique Device ID to function properly within a Vocia Paging World.
The Factory Default Device ID is 01. A Device ID of 00 is invalid and cannot be used.
To assign a Device ID of hex 07, leave the MSB switch on 0 and turn the LSB switch to 7. Device ID
switches should be set using a 0.1 inch (2.5mm) to 0.12 inch (3.0mm) flat blade screwdriver.
NOTE
Changes made to the Device ID while connected to the network require a power cycle of the device in order to take effect.
