HD-SDI Video Board
Card P/N 903-5060-XX
The HD-SDI video board is a media converter card for fiber optic transmission of one high speed,
high-definition digital video signal between the remote and console modules. The HD-SDI board is
designed to receive and transmit signals that conform to the SMPTE 292M specification.
The HD-SDI card is a Model 907 PC/104 form-factor card mounted on a Model 907 Eurocard adaptor
board. The adaptor board provides the necessary power supply regulation and optical bushings to
connect the 907 card to a 903 system. The 907-HDV (HD-SDI) media converter card mounted on the
907-EURO (Eurocard adaptor) uses an SFP transceiver with a high data rate to support the 1.5 Gbaud
signals.
6.4.1 Input/Output
The HD-SDI-R card is configured for digital video input at the remote unit; the HD-SDI-C card is
configured for digital video output at the console unit. The HD-SDI cards may be installed in any data or
media converter slot. Typically slots H and I are used for media converter cards only, which get power
from the backplane but transmit and receive optically.
At the remote (subsea) end, the camera signal is input at SMB jack J1, as shown in the figure below. At
the console (surface) end, the HD-SDI monitor or signal processing equipment is attached to jack J3. A
front panel view of the card shown in Figure 6.4-1 indicates the location of the external LED connector.
