Adjusting Remote Commander
The camera section is adjusted by changing the constant or
coefficient of the digital signal processing calculation, or
modifying the output voltage of the EVR IC (VC-132 board
IC654). This is controlled by the camera micro processor
(VC-132 board IC653), which reads the data written in the
nonvolatile memory (VC-132 board IC641: EEPROM), and
transmits it to the digital signal processing circuit and EVR.
To perform .adjustments, adjustment. data . written ..
in ...
the
nonvolatile memory must be rewritten, using the adjusting
remote commander.
The adjusting remote commander uses the remote commander
signal line (LANC) to communicate mutually with the camera
microprocessor. The page, address and the up/down commands
of the data are transmitted from the adjusting remote commander
to the camera micro processor. And, the page, address, and data
are transmitted for the vice versa.
1.
Using the adjusting remote commander
1)
Connect the adjusting remote commander to the remote
control terminal (DD-55 board J452).
2)
Adjust
the
HOLD switch
of the adjusting
remote
commander to "HOLD" (SERVICE position).
If it has been properly connected, the LCD on the adjusting
remote commander will display as shown in Fig. 7-6.

3)
Operate the adjusting remote commander as follows.
• Changing the page
The page increases when the EDIT SEARCH+ button
is pressed, and decreases when the EDIT SEARCH-
button is pressed. There are altogether 16 pages, from 0
to F.

• Changing the address
The address increases when the FF (
* )
button is
pressed, and decre.ases when the REW (
~
) button is
pressed. There are altogether 256 addresses, from 00 to
FF.
• Changing the data (Data setting)
The data increases when the PLAY ( .... ·)
pressed, and decreases when the STOP

pressed.
There are altogether 256 data, from 00 to FF.
• Writing the adjustment data
The PAUSE button must be pressed to write the
adjustment data (F page) in the nonvolatile memory.
(The new adjustment data will not be recorded in the
nonvolatile memory if this step is not performed.)
4)
Select page: 6, address: 00, and adjust the data to 01. This
releases the write protect of page F, and enables the camera
section (Addresses 01 to DF of page F) to be adjusted.
5)
After completing all adjustments, tum off the main power
supply (7.5V) once. This release the adjustment mode
(other than page F).
2.
Precautions upon
using the adjusting
remote
commander
Mishandling of the adjusting remote commander may erase the
correct adjustment data at times. To prevent this, it is
recommended that all adjustment data be noted down before
beginning adjustments and new adjustment data after each
adjustment.

The data already listed in the adjustment data memo
column are fixed values.
Note 2: The adjustment data initial values are values just after
executing "Page F Data Initialization" and "Page F
