1-5. HOW  TO  WRITE  DATA  TO  INTERNAL  MEMORY
Usually, the camera has been set so as to disable the data writing from the PC to the internal memory of the camera.
This setting must be changed temporarily when the data is to be written to the internal memory such as a case after the board replacement.
To change the setting, use the write enable tool “WriteEnableTool.exe”.
Data writing method
1) Connect the PC to the camera (USB mode: Mass Storage), and switch the driver to the “Sony Seus USB Driver”.
2) Start the Write Enable Tool and the SeusEX.
3) Click the [Activate Write Enable Mode] button of the Write Enable Tool.
4) Upon completion of the setting change, the following message will be displayed.
5) Return the driver to the original one, and connect the PC to the camera (USB mode: Mass Storage).
6) Write the data read out into the PC to the internal memory of the camera.
7) Disconnect the PC from the camera, and turn off the camera.
Note:
By turning off the camera, the write enable setting is reset.

and tantalums.
• Chip resistors are 1/10 W unless otherwise noted.

• Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum
capacitor, Because it is damaged by the heat.
• Some chip part will be indicated as follows.

• Constants of resistors, capacitors, ICs and etc with XX
indicate that they are not used.
In such cases, the unused circuits may be indicated.
• Parts with 
 differ according to the model/destination.
Refer to the mount table for each function.
• All variable and adjustable resistors have characteristic
curve B, unless otherwise noted.
• Signal name

(Measuring conditions voltage and waveform)
• Voltages and waveforms are measured between the
measurement points and ground when camera shoots
color bar chart of pattern box. They are reference values
and reference waveforms.
(VOM of DC 10 M
 input impedance is used)
• Voltage values change depending upon input
impedance of VOM used.)
THIS NOTE IS COMMON FOR SCHEMATIC DIAGRAMS
(In addition to this, the necessary note is printed in each block)

2. Adjust the distance so that the output waveform of
Fig. a and the Fig. b can be obtain.
When indicating parts by reference number, please
include the board name.

Precautions for Replacement of Imager
• If the imager has been replaced, carry out all the adjustments
for the camera section.
• As the imager may be damaged by static electricity from
its structure, handle it carefully like for the MOS IC.
In addition, ensure that the receiver is not covered with
dusts nor exposed to strong light.
