Integrated Netlinx Nx Master Functionality - AMX DGX1600-ENC Hardware Reference Manual

Audio Insert/Extract Board
The Enova DGX 800/1600/3200 holds up to two AIE expansion boards. The Enova DGX 6400 holds up to eight AIE expansion
boards.
Embedded audio signals switch with the video channels. Through the use of the Audio Insert/Extract Board, embedded audio can
be extracted and external audio matrix switches can be executed (using a separately purchased audio matrix switcher like the
Precis DSP) and then reinserted post-switch on the output side. For complete information on the Audio Insert/Extract Board, see
page 154.
IMPORTANT: Setting the DIP switches is the only mechanism for configuring the Audio Insert/Extract Board to either insert or extract
audio. Therefore, setting the switches (which requires removal of the board from the enclosure) should be done at the time of
installation.

NOTE: Enova DGX 800 only – AIE Board connectors 1-8 in the left and right expansion board slots correspond to standard connectors
1-8 on the input and output boards respectively. AIE connectors 9-16 are inoperable.
MAC Address
The MAC address for the system is located directly above the Control (DB-9 serial) port on the CPU.
Serial Number
The serial number is normally located on the rear of the enclosure on the left. Before installation, we recommend recording the
serial number for the enclosure (and for each module and/or wallplate if applicable) in an easily accessible location.

Integrated NetLinx NX Master Functionality

The integrated NetLinx NX Master in Enova DGX enclosures is a NetLinx NX Controller.
Network Connection
The default IP address for the ICS LAN network is 198.18.0.1 with a subnet mask of 255.255.0.0.
IMPORTANT: The LAN 100/1000 (public network) and ICS LAN (private network) subnets must not overlap. If the LAN 100/1000
port is configured such that its address space overlaps with the ICS LAN network, the ICS LAN network will be disabled. The DGX
communicates with the 5002 device (and any endpoint in Auto-setup) via ICS LAN. Since those devices have fixed static IP addresses
on the ICS LAN network, you cannot change the 198.18 subnet information on the DGX platform of processors. You can only change
the Host name and DHCP server settings. Additionally, if connecting the Enova DGX's LAN 100/1000 port to an NX-x200 NX
Integrated Controller's ICS LAN port, you MUST change the NX Master's ICS LAN port settings (via the SET ICSLAN telnet command)
to choose a different subnet than the default 198.18.x.x or else the Enova DGX's 5002 switcher device (and any endpoint in
Auto-setup) will not come online.
DHCP Server
The ICS LAN port has a built-in DHCP server. This DHCP server is enabled by default and will serve IP addresses to any connected
devices set to DHCP mode.
The DHCP server can be disabled from a Telnet session with the integrated NetLinx NX Master with the command: SET ICSLAN.
The DHCP address range is fixed.
The server will provide addresses in the range 198.18.0.2 through 198.18.63.254.

Devices using static IP addresses on the ICS LAN network should be set within the reserved static IP address range of

198.18.64.1 through 198.18.127.254.
Do not use addresses in the range 198.18.128.1 through 198.18.129.254, as they are reserved for future upgrades.

The server supports TX and RX (endpoint) Auto-setup with addresses in the range 198.18.130.1 through 198.18.135.254.

IMPORTANT: The ICS LAN port on the left of the CPU is for communication via Telnet of endpoint devices connected to the integrated
Master in Auto-setup Mode. The ICS LAN allows the DGX to provide Private IP addresses to all connected endpoints while only
consuming a single IP address on the Public LAN. Please note, however, that the ICS LAN port serves DHCP addresses to any
connected device. If the ICS LAN is inadvertently connected to the Public LAN, devices also on the Public LAN may experience DHCP
address conflicts.
