•
The encoders discussed in this guide are housed in mountable enclosures with decorator-
style wallplates. The encoders can be mounted in Underwriters Laboratories (UL) standard
wall boxes or using the included mud ring.

About the NAV System
The Extron NAV decoders and one or more compatible encoders form an AV distribution
and switching matrix on an Internet Group Management Protocol (IGMP) Managed IP
Network. The encoders are configured for low latency multicast streaming. The decoders
are configured to join the assigned multicast group.
About the Encoder
A NAV encoder inputs an HDMI video signal and generates a video and audio stream
that can be transmitted over an IP network using the Extron PURE3 Codec algorithm to
compress the data. The PURE3 Codec exceeds many of the performance characteristics of
existing compression formats and provides exceptionally robust protection against network
errors, making it ideal for quality-critical applications.
The data stream can include:

Features
NAV E 401 D Encoder — Streams HDMI video and audio over a managed 1G IP
network. Also supports Ethernet extension.
NAV E 201 D Encoder — Streams HDMI video and audio over a managed 1G IP
network.
•
The NAV E 401 D and NAV E 201 D are both referred to as an "encoder." They are
referenced by model name when differences exist.
•
NAV encoders and decoders collectively are referred to as "endpoints."
HDCP-compliant HDMI video (which can include embedded digital audio [SMPTE 299M
and SMPTE 272M-A]) at resolutions up to 4k @ 60 Hz
RS-232 and IR control signals
NAV E 401 D only — An Ethernet Extension port allows communication to the same
network.
