Sdi-86G - Sony HDCU3300 Maintenance Manual

AU-302 board
The AU-302 board is an interface to the front INCOM
connector, and has the intercom control switch and indica-
tors.
Rear boards
SDP-15 board
The SDP-15 board processes the main-line signals sent
from the OTR-1 board and the return signals to the OTR-1
board, and selects the VF signal. The board converts one
channel of the six-channel main-line serial signal sent from
the OTR-1 board from the serial to parallel signal.
Then, it separates the digital audio signal and the com-
mands multiplexed to the main line, and sends the digital
audio signal to the AVP-6 board and commands to the AT-
167S board.
Also, the return video signal is sent from the DTX-5 board,
the digital audio signal from the AVP-6 board, and com-
mands from the AT-167S board. The board then multiplex-
es the digital audio signal and the commands to the return
video signal. The return signal is then converted from the
parallel to serial signal, and sent to the OTR-1 board as the
serial signal.
The SDP-15 board selects one channel from the triple-
speed VF video signal sent from the DPR-271A board and
the normal-speed VF video signal sent from the DPR-271B
board, and then sends the signal to the OTR-1 board.
OTR-1 board
The OTR-1 board separates the main-line signals sent from
the camera, and multiplexes the return signals to the
camera. The board converts the main-line light serial signal
sent from the camera from light to electricity and from the
serial to parallel signal.
Then, it separates the multiplexed main-line signal into six
channels, converts each of them from parallel to serial, and
sends them to the SDP-15 board as the six-channel serial
signal.
Also, the OTR-1 board converts the serial return video
signal and the serial VF video signal sent from the SDP-15
board into the parallel signals and multiplexes them. The
multiplexed return signal is then converted from the
parallel to serial signal, and electricity to light, and sent to
the camera as the light serial signal.

. I/F of MIC REMOTE, WFM REMOTE, and I/O PORT
of the D-Sub 15 pin connector
. SYNC output, CHARACTER output
. Retains serial numbers in EEPROM.
ADO-10 board

HIF-25 board
The HIF-25 board has the co-axial connector for outputting
the HD/SD-SDI signals to external devices.
The board outputs two systems of the main-line system
HD/SD-SDI signal sent from the DRX-5 board, and
outputs two systems of the monitor-system HD/SD-SDI
signal.
SDI-85 board
The SDI-85 board inputs the return signals of HD-SDI
from external devices.
The board has four systems of the return input of the HD-
SDI signal, which are selected and then sent to the DTX-5
board.
SDI-86G board
The SDI-86G board mainly inputs the return signals of SD-
SDI from external devices and the composite analog return
signals.
The board has four systems of the return input of the SD-
SDI signal, which are selected and then sent to the DTX-5
board. Apart from that, it has four systems of the return
input of the composite analog signal from the CN-2674G
board, which are selected and then sent to the DTX-5
board. It also has two systems of the amplifier for the
prompter signal from the CN-2674G board that is ampli-
fied and then sent to the DTX-5 board.
HIF-27 board
The HIF-27 board has the coaxial connector for outputting
the HD/SD-SDI signals to external devices.
It outputs two systems of the main-line system HD/SD-
SDI signals sent from the DRX-5 board, and outputs one
system of the monitor-system HD/SD-SDI signals.
