Chapter 1: Introducing Your New N2151/N2251 4K Devices
Product Overview
The NMX-ENC-N2151 4K Encoder and NMX-DEC-N2251 4K Decoder provide users with the industry's most versatile solution for
distributing AV over a converged network at resolutions up to 4096×2160. JPEG2000 compression allows Ultra HD media to be
switched and distributed over standard Gigabit Ethernet networks. Ultra HD signals from the NMX-ENC-N2151 Encoder are
provided simultaneously as: 1) a JPEG2000-compressed 200-600 Mbps stream through the RJ45 connector or small-form-
pluggable (SFP+) port (10Gb), and 2) an uncompressed stream through the SFP+ connector (via a fiber module). Any source can
be sent to any number of displays by routing through managed switches. System scalability is limited only by uplink and stacking
connector bandwidths.
Standard features like output scaling (Decoder), bi-directional serial, IR output, embedded 7.1 audio, and KVM-over-IP extension
are included. The NMX-ENC-N2151-C and NMX-DEC-N2251-C form-factors are compatible with the NMX-ACC-N9206 card cage for
high-density applications.
The NMX-ENC-N2151 and NMX-DEC-N2251 together create the perfect solution for video matrix applications where resolutions up
to 4K are required. Common applications include classrooms, conference rooms, performing arts centers, and sports bars.
Features include:
Output Scaling — Video scaling at the output (Decoder) allows seamless switching from any source, at any resolution, to
any display or projector, while preserving video fidelity.
Infrared (IR) — Infrared emitter connection allows control of low-cost, IR-only display devices.
Onboard Control — All N-Series Encoders and Decoders have on-board, built-in control capability via events that can
trigger any number of TCP/UDP commands to other IP controllable devices.
Pass-through HDMI interface (Encoder) — allows easy installation with local display such as desktop PC applications.
Unlimited Scalability — Grow the video matrix by adding Encoders or Decoders as needed (within the bandwidth limits of
the uplink and stacking connectors).
Stand Alone or Card — Available as a stand alone device, or card for use with NMX-ACC-N9206.
