General Information The Networked Receiver Controller (NRC) is a single node network device capable of simultaneously: • controlling and configuring up to 8 attached receivers for data collection • collecting and digitizing each receiver’s analog audio output signal • formatting and routing the digitized receiver’s signal to an attached network client. A simple diagram of the NRC system is shown below. Networked Receiver Controller R E CONTROL C E NRC

Channel Architecture A channel defines a virtual connection between a client application and a receiver connected to the NRC. There are two types of channel connections which can be established to a receiver; a Primary connection and a Piggy-back connection. 1. A Primary Connection a. A Primary connection is established with a receiver when the receiver is free of any other client connections. b. A Primary connected client has full access and control of the receiver and its resources

Universal Receiver Translation/Abstraction The NRC abstracts the user from each receiver’s proprietary low-level communications protocol by presenting a common receiver translation software tasking interface to the user. This common software interface allows the user to task the receivers at a logical level without the need to worry about how to implement this tasking. This allows a wide range of different receivers to be tasked via the NRC in the same manner regardless of the number, model

Hardware Installation Step 1: Receiver Audio Signal Termination Type The NRC supports both differential and single-end audio signals, with the factory system default being configured to support Differential Mode. If Single-End mode is required, proceed as follows: 1. Ensure the NRC is powered off 2. Remove the top cover of the NRC. 3. Locate the two banks of 4x DIP switches, D1 and D2. 4. Set all switches to the ON position for single-ended operation. a. Conversely, set each switc

NRC Configuration Prerequisites: In order to successfully configure the NRC for operational use, the installer must have access to: a. a terminal emulation program i. Before using it on the network the NRC must be properly configured, by running a configuration utility on the NRC through a remote terminal session. This requires connecting serially to the NRC from another computer. The operating system of the computer is not important as long as it has a compatible terminal emulation prog

If this is the first time the NRC has been turned-on, once the NRC has completed its initial system boot-up process, the NRC system LCD graphics files will be uploaded into the LCD display. The NRC’s LCD display will indicate which LCD memory location the current image is being uploaded into and once this image upload process is finished, the LCD display will be activated and display 8 channel status windows above the status 1 message “www.aegis-inc.net”. 7. Once the NRC has reached this s

Step 3: Configure Network Settings Before the NRC can be accessed from the network, it must be assigned a network address. Select option 2 to configure the network options. Below is a screen sequence example as the IP address settings are configured. Configure network settings: Present settings for device eth0: Local IP address = 192.168.1.159 Netmask = 255.255.255.0 Broadcast address = 192.168.1.255 Network address = 192.168.1.1 Enter the following new values.
