1-3-25. HC-54 Board
The HC-54 board in the handle is a connector board for relay between the unit and the handle.
This board relays switch signals of the handle, GPS receiver, and power and communication lines of the MI SHOE.
1-3-26. KSW-72 Board
The KSW-72 board contains a power LED, an inside key switch, a button battery, LEDs for ASSIGN7 and ASSIGN8, and an audio
headphone/speaker amplifier DAC (IC8402).
The power LED lights when power is turned on.
The inside key switch signals are input to the ADC port of IC6000 on the DPR-394 board.
1-3-27. SW-1757 Board
The SW-1757 board contains ASSIGN 1, ASSIGN 2, and ASSIGN 3 buttons and an LED DISPLAY button.
1-3-28. FU-84 Board
The FU-84 board contains a multifunction dial.
1-3-29. SEC-59 Board
The SEC-59 board contains a WB SET (white balance set) button.
1-3-30. HP-181 Board
The HP-181 board contains a headphone jack.
Audio signals are connected to the output pins of IC8402 on the KSW-72 board.
1-3-31. TC-118 Board
The TC-118 board contains a TCIN/TCOUT (timecode input/output) connector and a GENLOCK IN (for Genlock input)/REF OUT
(sync signal output) connector.
Both input and output timecode signals are connected to IC3501 on the DPR-394 board.
The Genlock signal is isolated to H/V/F sync signals in IC5108, and then these signals are input to IC3501 on the DPR-394 board.
The Refout signal is output from IC3501 on the DPR-394 board. Its waveform is shaped in the circuit of the TC-118 board and is
then output to the external circuit.
1-3-32. SDI-127 Board
The SDI-127 board contains a BNC connector (SDI OUT 1 connector) that can output 12G-SDI signals and a BNC connector (SDI
OUT 2 connector) that can output 3G-SDI signals.
IC6004 is a 12G-SDI driver IC.
IC6003 is a 3G-SDI driver IC.
1-3-33. VIF-78 Board
The VIF-78 board contains a connector for connection to the viewfinder. This connector is connected to the PD-129 board through
the viewfinder cable.
1-3-34. VIO-38 Board
The VIO-38 board relays signals between the camera body and the outside connector.
This board contains IC302 that sends panel control signals.
