1-6. Circuit Description
1-6-1. Video Signal System, System Control (MPU-126 Board)
The MPU-126 board composed of the video signal system that processes a video signal from a connected
camera to output to the LCD panel or outside, the system control that performs the entire system control,
and a part of the power system. (For the power system, refer to Section 1-6-3.)
Video Signal System
In the video signal system block, the video composite signal from the camera connected to the REMOTE
connector is compensated by the Cable Compensator. The length of the compensation cable is switched in
the Analog SW (IC401) using the control signals CABLE 0 and 1 from the PIO (IC309).
The video signal that is processed in the amplifiers Q407 to Q413 and the buffer circuit has two routes:
one is output to outside through the MONITOR connector (BNC), and another is converted to the RGB
signals for LCD in the LCD Video Signal Decoder (IC404). The operation clock for the LCD Video
Signal Decoder (IC404) is controlled according to a destination of a device connected, and is input after
the Relay (RY401) switches between the operation clocks NTSC and PAL.
The sync signals VIDEO HD/VD for the video signal are generated in the SYNC Separator (IC409). The
RGB signals that displays the menu are generated in the RGB D/A Converter (IC109) from the output
data (DA R0-7, DA G0-7, and DA B0-7) of the PLD (IC111). The video signal and the menu displayed
on the LCD panel are switched with the Analog SW (IC406) for the RGB signals, and with IC116 for the
sync signals.
System Control
The MPU-126 board mounted the 32-bit CPU (IC5), which controls the entire system. The CPU (IC5)
operates with the ROM (IC6) that the operation program is written in. Using the memory stick, the
operation program can easily be upgraded from outside by the Memory Stick Interface (IC313). The
MPU-126 board also mounted the general memory SRAM (IC8 and IC9) and the FRAM (IC10 and IC11)
that records the system setting conditions. These devices and the CPU (IC5) controls each input/output
signal through the PIO (IC306 and IC309) with the 8-bit bus.
The PLD (IC111) controls the color palette for menu display, the switch for output characters, the menu
display and CPU (IC5). The PLD operates with the EEPROM (IC110) that the control program is written
in. This control program can be written/rewritten from the EPR connector (CN101) through IC108 using
the PLD download fixture. Sending/receiving of the serial data for a device that is connected to the
REMOTE connector is controlled by the communication IC (IC305) through the RS232C Transceiver
(IC302). The level of buzzer (BZ2) on the VR-284/284A board is controlled in the D/A Converter
(IC303, IC311, IC312, IC314).
The CPU (IC5) controls these entire system, and also communicates by the serial data with the 8-bit sub
microcomputer (IC1) that controls the operation panel, knobs and LED display on the LED-406/407
board.
The CPU (IC5) operates with the 4 MHz clock, which is generated from the clock signal of the 36 MHz
reference oscillator (X2) using the 1/9 dividing circuits (IC20 and IC21).
The 18 MHz clock, which is generated from the clock signal of the reference oscillator (X2) using the 1/2
dividing circuit (IC4), is used as the operation clocks for the communication IC (IC305), memory stick
interface (IC313), PLD (IC111), and the 8-bit sub microcomputer (IC1) on the LED-406/407 board.
Other clock data are generated in the Clock Oscillator (X301) and the Clock IC (IC310).

1-6-2. Control System for Panel Operation and Display (LED-406/407 Boards)
LED-406/407 Boards
The LED-407 board and the LED-406 board is installed in the RCP-D50 and RCP-D51 respectively.They
differ in the shape of the panel and the operation knobs. However, the functions of both circuits are the
same: operation and display on the panel and their controls. The 8-bit sub microcomputer (IC1) commu-
nicates with the MPU-126 board by the serial data, and controls the panel operation and display by the
input signal of each button and knob. The 8-bit sub microcomputer (IC1) controls the displays of the
LEDs (D1 to D15) for illumination switches by the digital signal through the LED Decoder (IC3) and the
LED Drivers (Q21 to Q32, and Q59), and also controls the display of the 7-segment LED (ND1 and
ND2) and the dot matrix LED (ND3).
1-6-3. Power Block (MPU-126 Board, VR-284/284A Board)
Each part on the MPU-126 board and the VR-284/284A board mounts the power circuit.
Power Block on the MPU-126 Board
Through the REMOTE connector, the external power input (UNREG) becomes the +5 V power in the +5
V Regulator (*1), and this +5 V power becomes as follows.
.+3.3 V power in the +3.3 V Regulator (IC112).
.+3.3 V analog power in the +3.3 V Regulator (IC104).
.+2.5 V power in the +2.5 V Regulator (IC105).
The +12 V power from the VR-284/284A board becomes as follows for exclusive use in Video Signal
System, and they are supplied to the Video Signal System as the dedicated power.
.+7.3 V in the +7.3 V Regulator (IC408).
.+5 V powers in the +5 V Regulator (IC407).
These powers are supplied as the drive power to each board.

Power Block on the VR-284/284A Board
Through the REMOTE connector, the external power input (UNREG) becomes the drive power for LCD
in the LCD Regulator (*2). The +5 V power generated on the MPU-126 board becomes as follows.
.+14 V power in the +14 V Regulator (*3).
._5 V power in the _5 V Regulator (*4).
Also, the +14 V power becomes as follows.
.+12 V power in the +12 V Regulator (IC9).
.+5 V power in the +5 V Regulator (IC8).
These powers are supplied as the drive power to each board.
