d LAN port 1 (RJ-45 port) — Use either this port or the fiber optic network port (e) to
stream video and audio data across a network, to control the VN-Matrix system, or both.
e LAN port 2 (fiber optic port) — Use either this port or the RJ-45 network port (d) to
stream video and audio data across a network, to control the VN-Matrix system, or both.
NOTES: • Do NOT connect VN-Matrix units to an existing network until each is
correctly configured. Incorrect configuration may cause disruption to
other network users.
• See “RJ-45 port wiring“ on page 22 to make a cable for LAN port 1 (d).
• See “Configuring Network Settings“ on page 16 to configure the units.
• Extron does not supply the plug-in SFP module for the optical Network
port.
f SDI Out BNC connector —
NOTE: See “Video Input, Output, and Loop Connections“ for detailed
connection diagrams.
Encoder configuration — This connector provides a loop through of the original
source with or without an optional text overlay.
Decoder configuration — Connect an SDI, HD-SDI, or 3G-SDI digital video display to
receive the streamed digital video output.
g SDI In BNC connector —
NOTE: See “Video Input, Output, and Loop Connections“ on page 23 for
detailed connection diagrams.
Encoder configuration — Connect an SDI, HD-SDI, or 3G-SDI digital video input for
encoding and streaming to one or more decoders.
Decoder configuration — If desired, connect a a local SDI input or genlock signal of
the same resolution and refresh rate to synchronize the decoder to a local standard.
h Loop BNC connector —
Encoder configuration — This connector provides a buffered loop through of the
original source.
Decoder configuration — Not used.

Mounting the Units

CAUTIONS: • Installation and service must be performed by authorized personnel only.
• Ensure the vents in front and rear of the equipment case are not covered.
Detailed mounting instructions are in the “Reference Information“ section. The 1U high,
half-rack width VNC 325 codecs can be placed on a tabletop, without additional kits or
mounted on a rack shelf or mounted under a desk, using the optional applicable mounting
kit.

Planning the System Architecture

Before you make connections, plan how you will transport data (see “Data Transport
Methods“, below) and how you will route the streaming video and audio and the control
signals within the network (see “Data and Control Routing,“ on page 10).
