  • Front Panel Display – Features an LCD display on the front panel, making it easy to view status information, network settings, IP addresses & ICSLan Port status, among others
  • Redundant Power Source – The NX-4200 can be powered either with a connection to mains AC power (110/220VAC) or from an external 12V DC power supply. If the AC input power is lost or if the internal power supply fails, the NX-4200 will immediately switch to the 12V DC power input without interruption except to PoE devices on the ICSLan
  • Dual NIC with Power – Enables two discrete network interfaces for unrivaled security and includes a 4 Port switch with PoE allowing you to power PoE devices over a secure, isolated network. The LAN port is used to connect the master to an external network, and the ICSLAN ports connect to AMX or third-party A/V equipment isolated from the primary network
  • IPv6 – Supports Internet Protocol version 6 (IPv6), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet
  • IEEE 802.1X – Supports IEEE Standard for Port-based Network Access Control with the ability to grant or deny network access to devices wishing to attach to a LAN based on credentials tied to the device rather than to a user
  • X.509 Certificate Services – NX supports customer-provided certificates for access to protected networks
  • Full LDAP Integration – Supports multiple user-defined login groups for accessing the master, as well as provides an AMX programmer the capability to require network login to access certain areas of the touch panel
  • High Performance Architecture, Flexible Programming Platform (RPM, NetLinx and Java) – Easily scalable to support a wide range of applications for today and tomorrow
  • Full Line Compatible (Backwards and Cross-Compatibility) – Standardized port numbers and new configuration import/export tools mean fewer coding changes
  • TLS / SSH Client – Provides NetLinx programmers the ability to manage secure port TLS and SSH communications with a remote device or server
  • Cryptographic Support – In accordance with FIPS 140-2, a U.S. government computer security standard used to accredit cryptographic modules for the protection of sensitive or valuable data
