1-6-2. HDCU1000/1080
Front Board
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
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-86 board
The SDI-86 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-2674
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-2674 board that is amplified
and then sent to the DTX-5 board.
1-6-3. HDCU1500
Front board
AU-303 board
The AU-303 board is an interface to the front INCOM
connector, and has the intercom control switch, indicators,
and power supply switch.
Also, when using the optional remote control unit (RM-
B750) by connecting it to the front panel of the
HDCU1500, the AU-303 board functions as the interface
with the RM-B750.
Rear boards
HIF-27 board
The HIF-27 board has the co-axial 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.
SDI-87 board
The SDI-87 board mainly inputs the return signals from
external devices.
The board has the three systems of return input that can
connect the HD-SDI signal, the SD-SDI signal, and the
composite analog signal, specifies format for each system,
selects the system and then sends it to the DTX-5 board.
Also, it has two systems of amplifier for the prompter
signal from the CN-2675 board that amplifies the signal
and the signal is sent to the DTX-5 board.
1-6-4. HKCU1001
The HKCU1001 only supports the basic functions of
VBS_OUT, PIX_OUT, and WFM_OUT.
Front board
EN-159A board
The EN-159A board receives 8:4:4 component digital
signal from the front side (DRX-5 board), and outputs the
main-line system SD analog composite signals (VBS, PIX,
and WFM signals). The board is equipped with the exter-
nal synchronous circuit of the reference SC (sub carrier) of
SD, and the composite signal whose external SC is locked
can be output. There also is a through-path of the 8:4:4
component digital signal to the rear part (EN-159B board).
