Hardware Reference Guide - NX-Series NetLinx Integrated Controllers
What’s New?
The following section lists the new features for the NX-series controllers. For more information about each of these items, see the
What’s New for NX-Series Controllers document located on the NX controllers product pages at www.amx.com .
Two Discrete Network Interfaces (NICs)
The NX-2200, NX-3200 and NX-4200 controllers have two 10/100BaseT Ethernet connections. The first, designated as LAN, is
intended for connection to the Data Network for external network communications such as database access or scheduling. The
second, the ICSLAN is intended for communication with AV devices.
Using the ICSLAN Network
The ICSLAN 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.
For more information about using the ICSLAN network, DHCP servers, and opening LAN and ICSLAN sockets from code, see the
ICSLAN Ports on page 33.
Automatic Binding of AMX Devices on ICSLAN
When an ICSLAN device is set to NDP connection mode (the factory default), it will automatically be bound to the master when
connected to it’s ICSLAN port if it’s IP address is valid for the ICSLAN subnet.
Support for IPv6 Networks
The NX-Series controllers fully support IPv6 network addressing. If the LAN port is connected to an IPv6 capable network it will self
select an appropriate IPv6 address based on the discovered address parameters of the network to which it’s attached.
The controllers simultaneously support IPv4 network addressing. This means any controller may have more than one valid IP
address: one IPv4 and one or more IPv6 addresses.
Link-Local Fallback in DHCP Mode
When the X-Series controller’s 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 controller 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.
Wired 802.1X Support
The X-Series controllers support wired 802.1X, an IEEE Standard for Port-based Network Access Control.
ID Pushbutton Functionality
The X-Series controllers include new ID pushbutton functionality. For more information, see the ID Pushbutton on page 34.
Serial Ports Differences
Unlike current NI controllers, not all serial ports on the X-series controllers support RS-422 and RS-485. The NX-1200 and
NX-2200 have one serial port that supports RS-232/422/485, and the NX-3200 and NX-4200 have two. The rest of the serial
ports (1 on the NX-1200, 3 on the NX-2200 and 6 on the NX-3200 and NX-4200) support only the RS-232 protocol.
Serial, IR, and AxLink Port Diagnostics
When a string is sent to a serial port or an IR pulse to an IR port, the X-Series controllers can detect and report if the port being
used is in a fault condition. The controllers can also detect certain fault conditions on the AxLink bus.
AxLink Power Measurement and Control
Important: The NX-Series controllers can NOT be powered via the AxLink port. The +12V pin on the AxLink connectors are designed
only for voltage output. Do NOT c12V from a power supply or the NXA-PDU to the +12V pin on the AxLink connectors, or you
may permanently damage the NX controller and/or the power supply.
The AxLink ports on X-Series controller support a new NetLinx command to turn on and off +12V power output on the port.
Case Sensitive File System
Unlike the NI-Series controllers, all file names on the X-Series controllers are case sensitive. This includes all user files created or
used within NetLinx or Java code.
USB Program Port
The X-Series controllers utilize a true USB port for configuration and programming via a connected PC.
USB Firmware Upgrade
All X-Series controllers support firmware upgrades via a USB solid-state drive. Selecting the desired .kit file and initiating the
upgrade are done from telnet.
USB Program Download
All X-Series controllers support loading NetLinx program files via a USB solid-state drive. Selecting the desired .tkn file and
initiating the upload are done from telnet.
USB Logging
If a USB storage device is connected via an X-Series controller’s USB port it can be used to store a log of system status messages.
