5-2. Data Structure
The respective menu items can be classified into the categories of USER, OPERATION, PAINT and
MAINTENANCE. In addition to these categories, the respective menu items have different data in the
USER layer (it is not the USER category), PRESET layer, SERVICE layer and FACTORY layer.
USER layer :
Data that can be changed by menu operation. This layer is used mainly by users.
PRESET layer :
Data to be registered as the standard setup. This layer is mainly set up by video
engineer.
SERVICE layer
*
1
:
Data that can be changed by service engineer after entering the SERVICE mode.
As it cannot be modified by the user and video engineer, this layer is identical to the
default setup when shipped from the factory for the user and video engineer.
FACTORY layer :
Factory-adjusted values and fixed values.
*
1 : To change data in the SERVICE layer, be sure to set the switch S1-1 on the AT-143 board to ON.
*
2 : In the Camcorder of serial No. 70000 and No. 80000 series, the ALL menu cannot be selected. For details of the ALL menu, refer to
Section 4-2, “TOP Menu”.
The menu has the basic data structure as follows.
Actual setup data = FACTORY layer data (absolute value)
+
SERVICE layer data (relative value)
+
PRESET layer data (relative value)
+
USER layer data (relative value)
Note that some menu items (such as switch data and KNEE POINT data) do not have data in the FACTO-
RY layer and SERVICE layer. Such menu items have the basic data structure as follows.
Actual setup data = USER layer data (absolute value)
Registering the standard setup means transferring the setup data that is available as of this timing, to the
PRESET layer. In other words, when the standard setup is registered, the PRESET layer value and the
USER layer value are added so that the sum of the PRESET layer value and the USER layer value
becomes the new PRESET layer data while clearing the USER layer data.
Calling the standard setup means clearing the USER layer data.
When the standard setup is returned to the default setup (that is set when shipped from the factory), the
PRESET layer data and the USER layer data are cleared.
