1-3. Circuit Description

1-3-1. TG-289 Board
The TG-289 board contains a Gain switch and a WB switch.
1-3-2. AR-5 Board
The AR-5 board contains IC0700, IC0300, IC2101 and an SD slot.
IC0700 has an interface conversion function between IC0600 and IC6000 on the VC-41 board and an audio function.
The PCIe signal from IC6000 on the VC-41 board is distributed to four devices (IC2000, IC2101, IC2602, and wired LAN) through
IC0300.
The PCIe signal from IC0300 and the USB signal from IC2602 on the VC-41 board are connected to the SD card slot.
The PCIe signal from IC0300 is connected to IC2000 and IC2101, and is then converted to the SD IO signal. The SD IO signal is
connected to the SD card slot.
1-3-3. JK-106 Board
The JK-106 board contains IC6000 and an RJ-45 connector.
The PCIe signal from IC0300 on the AR-5 board is input through the VC-41 board to IC6000.
Ethernet signals from IC6000 are connected to the RJ-45 connector.
1-3-4. VF-98 Board
The VF-98 board contains IC1101.
The EVF parallel signal from IC0600 on the VC-41 board is converted to a serial signal in IC0900 on the VC-41 board.
This converted serial signal is input through the HN-441 board to the VF-98 board.
The serial signal is converted to parallel signals in the VF-98 board, and then the parallel signals are input to OLED EVF.
1-3-5. LD-136 Board
The LD-136 board contains IC9600, IC9700, IC9800, IC9840, IC9870, IC9550, and IC9551.
The lens is controlled through SIO communication from IC6000 on the VC-41 board.
The gyro signal of the SE-1187 board is input to IC9600 to drive the vibration-proof lens for image stabilization.
IC9700 controls IRIS and variable liquid crystal ND.
IC9800 controls focus and mechanical shutter.
The zoom and focus MR sensor signals are input to IC9800, IC9840, and IC9870.
The zoom lens is driven by IC9550 and IC9551.
1-3-6. SD-66 Board
The SD-66 board contains IC101 and an SDI connector.
IC101 inputs SDI signals from IC2300 on the VC-41 board and control signals from IC0600, and also outputs SDI signals.
SDI output signals from IC101 are output to external equipment from the BNC connector.
1-3-7. CT-287 Board
The CT-287 board contains a Wi-Fi module and IC4804.
IC4804 controls the lens using the control signals from IC6000 on the VC-41 board.
The Wi-Fi module sends data to and receives data from IC6000 on the VC-41 board.
Wi-Fi radio waves are emitted from the antenna on the WF-1008 board.
