VN-Matrix 300 • Introduction 10
Digital Video Connectors
The VN-Matrix 300 provides 3 BNC connectors for the connection of digital video sources.
The function of the connectors may change dependant on the configuration of the unit
(encoder or decoder mode).
Connector
Mode SDI – IN SDI - OUT SDI - LOOP
Encoder
(IP TX)
Digital Video
input
This connector provides a loop
through of the original source
with a text overlay (optional)
for identification purposes.
This connector provides a
simple re-clocked (buffered)
loop through connection of
the input source.
Decoder
(IP RX)
Digital Genlock
input (optional)
Digital Video output.
zThe video output will be
in the same format as the
originating source.
zWhen no video streams are
being decoded this output
can provide either a frozen
image of the last received
frame or a user definable
splash screen.
Not used
Power Supply Input
The VN-Matrix 300 requires a 12V DC regulated power supply (rated at 5A) via this
connector.
A suitable mains-operated power supply unit (PSU) is provided.
Network Connectors
These are used to connect the VN-Matrix 300 to an Ethernet network.
zEither port may be used for streaming images along with any associated audio and
ancillary data.
zIt is not possible to stream data from both ports simultaneously.
zEither port may be used for control and monitoring purposes.
zIt is possible to use one port for the streaming of image data and the other port for
control and monitoring purposes.
RJ45 – LAN 1 — Provides a 1000BASE-T connection.
SFP – LAN 2 — Provides for an (optional) 1000BASE-SX optical connection.
Serial I/O Connectors
COM1 and 2 are standard 9-pin D type connectors. These are used to establish a serial data
link between the VN-Matrix 300 and an external computer.
zCOM1 is used for low level conguration of the VN-Matrix 300 unit via a serial link.
zCOM2 is used for sending or receiving serial data across a network, for example for
control of external devices.
