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.
z
The video output will be
in the same format as the
originating source.
z
When 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.
z Either port may be used for streaming images along with any associated audio and
ancillary data.
z It is not possible to stream data from both ports simultaneously.
z Either port may be used for control and monitoring purposes.
z It 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.
z COM1 is used for low level configuration of the VN-Matrix 300 unit via a serial link.
z COM2 is used for sending or receiving serial data across a network, for example for
control of external devices.
