Operation

Using the NRC

Starting the NRC

After pressing the power button, the NRC may take up to 60 seconds to initialize and be ready for operation. Initially the display will show “ Networked Receiver Controller” and NRC version. When initialization is complete, the NRC LCD display will be activated and display 8 channel status windows above the Aegis status message “ www.aegis-inc.net” .

Power-On Self Test (POST)

A Power-On Self Test (POST) is a receiver connection integrity test is an integral part of the NRC. During this test, the control and audio connections for each channel are checked for proper connection and operation to and with the NRC.

The POST configures each NRC attached receiver to generate and output a unique frequency analog test tone, which is then digitally processed to ensure it is at the expected frequency. If the NRC is able to successfully configure the receiver and process the audio test tone then the receiver is deemed to have passed the POST and be available for use. The success or failure of each channel’s POST test is reported on the LCD display4.

This POST is run on a per-channel basis when:

1.A new receiver type is attached to the NRC and configured for the channel.

2.A receiver is powered on or otherwise comes online, including when the NRC is initially turned on or re-boot.

3.A receiver is “ reboot” via the Java GUI.

Note: If the receiver for some reason goes off-lineand then returns on-linewhile there is at least one client already connected to that receiver, the POST will not run until all attached clients disconnect from that receiver channel. This allows the NRC to run the POST in the background only when the receiver is free. When a POST is running, clients will be inhibited from connecting to the channel until the POST test is completed (~1-2sec).

Interpreting the LCD Display

The LCD display contains important information regarding the status and use of the NRC. During normal operation, the LCD will display a symbol reflecting the current status of each channel, with the display’s left-most symbol being channel 1’s status across to channel 8’s status on the right hand side.

Only one symbol is displayed to reflect the status of a given channel and hence the symbols have an inherent priority and hence only the highest priority symbol will be displayed.
