4.2.4 Interface to Video
Use the SDC ports ‘CV IN’ and ‘CV OUT’ or ‘S-VIDEO IN’ and ‘S-VIDEO OUT’
1. Video input – Use appropriate input port for your format (COLOUR CV IN or S-VIDEO IN)
These are clearly marked on the Panel PC Comms module.
The standard SDC accepts video input in PAL or NTSC format from a camera mounted on the
ROV. Apply the video signal to the SDC through the appropriate video input port. Teledyne
TSS supplies CV cables (dual phono to phono) and a pair of BNC to phono adapters to assist
video connection with the 440 System.
Note that you cannot display the video channel on the SDC screen.
The SDC mixes video images from the sub-sea camera with graphical information generated by
the SEP. You may view the composite image through the appropriate video output port.
2. Video output – Use appropriate output port for your format (COLOUR CV OUT or S-VIDEO
OUT)
The format of the SDC video output signal will match that of the input video signal. That is if
your input is PAL, then the output will be PAL. Similarly if your input is NTSC then the output
will be NTSC. Further the video output will reflect the specific connections used i.e if the video
input is monochrome CV, the output will be monochrome CV and will be provided via the
‘MONO CV O/P’ port (similarly colour CV input will provide via the ‘COLOUR CV O/P’, and S-
Video output will be provided via the ‘S-VIDEO O/P’).
You may connect this signal to a standard video monitor using 75

screened cable. The output
can drive a single monitor or multiple monitors if you add a suitable video drive amplifier.
4.2.5 Interface to Analogue Outputs
NOTE
The analogue output has been redesigned for the SDC10. On previous versions
of the SDC, the analogue output was not included as part of the customer pack-
age. However, the SDC10 includes the analogue output as a standard component
integrated into the Rear Comms Enclosure.
4.2.5.1 SDC10 Analogue Output Overview
The Analogue Output operates directly from the DeepView for Windows external output. The external
output (COM3) is hard-wired to the analogue PCB input via a bespoke cable loom. This cable should
not be removed or modified without contacting Teledyne TSS. If the external output is disabled via
DeepView, the Analogue Output will not provide any outputs.
The Analogue Output is configurable via DIP switches located on the underside of the Comms
Enclosure facing the rear of the Panel PC. These switches can only be accessed by removing the Rear
Comms Enclosure. It is recommended this task is carried-out before the SDC is installed. Refer to sub-
section 4.2.5.2 "Analogue Output DIP Switch Settings" for instructions to remove the Comms
Enclosure and configure the DIP switches.
The analogue output interface provides three analogue outputs at the BNC connectors located on the
external Comms Enclosure. Each output varies in amplitude and polarity with the lateral offset of the
target. The CH1, CH2 and Quality BNC connectors represent unqualified data, qualified data and
quality flag where the qualified data, (CH2), is gated by the quality flag.
