Important Notes on Using Expansion Boards

ASB-DAN, ASB, and AIE boards are not compatible with one another and cannot be used in the same system.

ASB and AIE boards use terminal block connectors to bring auxiliary audio into the system and/or out of the

system.
ASB-DAN/ASB and AIE numbering overlays are provided, which can be applied to the I/O board numbering plate

(see the relevant board chapter), which is across the top or down the center (depending on the enclosure).

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.
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 DGXs 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 DGXs 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. 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.

Opening Public LAN and ICS LAN Sockets from Code

The integrated NetLinx NX Master opens sockets from NetLinx or Java code on whichever network has an IP subnet that
matches the address provided in the command to open the socket. No other indications are provided for which network
is in use, only whether the socket is successfully created.

Integrated NetLinx NX Master Features

The integrated NetLinx NX Master supports the following features:

Automatic configuration of AMX devices via ICS LAN (private network)

Link-local fallback in DHCP mode (IPv4 only)

Wired 802.1x (security for protected networks)

IPv6 network addressing

ID Pushbutton

Case sensitive file system

Differences in DEFINE_PROGRAM execution

USB Program port driver for Windows 7 and Windows 8

Telnet Commands for the Enova DGX 100 Series NetLinx NX Master


Automatic Configuration of AMX Devices via ICS LAN

When an ICS LAN capable endpoint device (e.g., a DXLink Twisted Pair Transmitter connected to a DXLink Twisted Pair
Input Board) is initially connected, the integrated Master sends ICS LAN messages to the device and conducts automatic
configuration (auto-setup), after which the device reboots.
If the Master is set to serve DHCP addresses and the device is set to DHCP addressing mode, a stable connection is
assured. Since these are the factory default settings for the devices, automatic configuration is the expected behavior for
all new equipment.
Even after being automatically configured for a Master in this manner, if the device is disconnected and reconnected to
a different Master, its old configuration will be forgotten and it will establish a new configuration with the new Master to
which it has been connected. Once connected, the device can also be configured for a different connection mode if
desired.
