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.
Device auto-setup status is discoverable via NetLinx Studio such that Auto-setup device IP addresses reside in the 198.18.x.x
space where the first “x” represents either 130 (input side) or 134 (output side) and the second “x” represents an individual port
number.
Transmitter endpoints: 198.18.30.x (where x is the input channel)
Receiver endpoints: 198.18.134.x (where x is the output channel)
Device numbering in NetLinx Studio places auto-setup devices on the input side in the range 45001 to 45999 and devices on the
output side in the range 46001 to 46999.
Link-local Fallback in DHCP Mode (IPv4 Only)
When the integrated Master’s public LAN IP addressing mode is set to DHCP, it will attempt to acquire an IPv4 address from a DHCP
server for approximately one minute after boot. If the Master does not receive a valid DHCP address in that time (e.g. if a DHCP
server is not found), it will fall back to an IPv4 address in the link-local range.
IMPORTANT: Link-local is not an operational mode for the Master; it is a temporary addressing scheme to permit access over the
network so that IP settings can be modified. Do not commission the Master with a link-local IP address.
The default link-local address is 169.254.x.y, where x and y are the least significant two octets of the MAC address. The Master will
first verify that this address is not taken by another device on the network. If the address is taken, the Master uses a standard
algorithm to find an available IP address in the link-local range.
When the Master is using a link-local IP address, the status light will blink once per second. If the Master’s network settings remain
in DHCP mode, it will attempt to acquire a DHCP address every five minutes until successful. After each failed attempt to acquire a
DHCP address, the Master will execute the link-local algorithm and may not fall back to the same link-local IP address.
Wired 802.1x Support
The integrated NetLinx NX Master supports 802.1X, an IEEE Standard for Port-based Network Access Control (PNAC). The Master
acts as a supplicant (client device) to an 802.1X enabled network and presents customer-provided X.509 certificates to be allowed
access to protected networks.
Support for IPv6 Network Addressing
The integrated NetLinx NX Master fully supports IPv6 network addressing. If the LAN 100/1000 port is connected to an IPv6
capable network, it will self-select an appropriate IPv6 address based on the discovered address settings of the network to which it
is attached.
The Master simultaneously supports IPv4 network addressing. This means any Master may have more than one valid
IP address: one IPv4 and one or more IPv6 addresses.
When opening sockets from NetLinx or Java code, no unique command is available to indicate that you are providing an IPv4 or
IPv6 network address. As long as the provided IP address is a valid IPv4 or IPv6 address, the Master will utilize the correct
addressing protocol automatically.
