VA-8600/VA-8600c REAR PANEL

Device ID Switches
The rotary ID switches are located on the back of the VA-8600 and VA-8600c and give the unit a unique Device ID. The switches are in
hexadecimal format. All VA-8600 and VA-8600c units must have a unique Device ID to function properly within a Vocia Paging World (i.e.,
it is not possible to have two VA-8600 and VA-8600c 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.
Power Entrance
The Power Entrance provides for connection of the appropriate power cord (included with unit). A switch selects the operating voltage
for the power supply, 110–120V or 220–240V at 50/60 Hz.
NM-1
NM-1 is the Network Module that is included with VA-8600 and VA-8600c. This module provides connectivity for control and audio via the
dual CobraNet interface and logic ports for the device failover functionality. The RJ45 connector labeled "Ethernet" is not used at this time.
Reset Button
Reset button, when held down for 5 seconds, performs a chassis restart. The Status indicator will flash yellow during restart and will turn
solid green once the process is complete.
Logic I/O
The Logic I/O connector on the NM-1 facilitates redundant device failover only. It is not a general-purpose contact closure interface.
See the Amplifier-to-Amplifier Failover section below.
