Operation
4.1
General
This Section contains information and instructions required for proper operation of the NXU-
2A. Refer to Figure 2-2 Control and Connector Locations for views of controls and
connectors.
4.2
Front Panel Indicators
All front panel indicator LEDs are explained below, starting at the left side of the unit.
4.2.1
Power LED
This yellow LED is lit whenever DC power is applied to the unit.
4.2.2
Link Active LED
The green Link Active LED is illuminated whenever the NXU-2A has an IP connection open to
another NXU-2A on the network. If this indicator is not lit, either the NXU-2A does not have
an active VoIP connection or the connection has been lost.
4.2.3
Channel Active LED
This green LED is lit whenever COR is active. This also indicates that the NXU-2A is sending
audio data across the IP link.
4.2.4
Audio Input LED
This yellow LED is provided as a visual aid in setting the proper input audio level for optimal
operation. See Section 4.4.2 Input/Output Level Adjustments for instructions.
