10. NW6044 Video Interface (option)
10.1 General
Where radars or ECDIS systems do not provide an Ethernet port (compliant to IEC61162-450 or
the IEC62388 radar video standard) and thus capable of broadcasting their information onto the
VDR network, this optional video interface module may be deployed to capture RGB, RGBHV,
Monochrome, and composite video information from radars, video cameras, ECDIS, and other
video sources.
This interface has 4 input ports for capturing images from a dedicated buffered output port of the
video source. The module digitizes the video signal and then outputs the video data through an
Ethernet port. Video modules can be configured for up to 4 inputs, enabling the VDR to capture
and record images from the primary radar plus up to 3 additional video sources. During installation
of the interface, the video system must be con
figured to accept each source’s video resolution,
interlacing, refresh rate, etc.
With each video interface a USB memory stick is provided with the Video Configuration Suite
(VCS2) application which must be used to configure the video interface before it is connected to
the CM.
Information about the settings is gathered from the <
VidChanX.ini
> file (based on its
VIDEOFORMAT entry information.) which is stored within the CM (core module)
If more than 1 source is specified by the MAXSOURCES entry, then Control Input/Output
connector signals are used to indicate the currently active source. The video signal configuration
is read, and a new image is captured. If the system is configured for 2 or more video channels,
then the next channel in the sequence is selected.
If the video module fails to capture an image because there is no video signal (i.e., radar is
OFF), an entry is made in the error log within the CM. However, this failure
will not generate
a video (error) caution on the BCU
. A video (error) caution is
only
triggered when a failure
is detected in the video capture hardware (i.e. bad or unpowered video module or Ethernet
cable path failure.
