VOCIA 8-CHANNEL LIVE AUDIO INPUT DEVICE (VI-8) REAR PANEL
Rear Panel Information
Caution – Due to potential energy hazard, connections to the Aux Power 24V DC inputs must be
made by qualified electrician or other qualified person as required to conform with all local codes.
Power
The VI-8 requires an external single 24V DC power source to operate, but is capable of accepting dual 24V DC inputs for redundancy. Both
power sources may be connected concurrently, however each must be capable of supporting the full 30 watt load of the unit (inputs are not
intended to load-share). Loss or return of either power source will not result in an interruption to normal operation as long as one of these
power sources remains functional. Monitoring of power sources is selectable via the Vocia Software.
The power connector is a four-way 5.08mm standard header with mating pluggable screw terminal block with cable restraint.
When power is present at either or both 24V power inputs the corresponding front panel green power LED will illuminate.

Device ID
The rotary ID switches on the VI-8 give the unit a unique Device ID. The switches are in hexadecimal format. All VI-8
units must have a unique Device ID to function within a Vocia Paging World (i.e. it is not possible to have two VI-8
units with the same Device ID of hex 07). To assign a Device ID of hex 07, turn the MSB switch on 0 and leave the
LSB switch to 7. To create an ID of hex B7, turn the MSB switch to B 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. 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.
