6-3. Data Structure of the SETUP Menu

6-3. Data Structure of the SETUP Menu
The menu has the following data structure.
Set value of the data (or adjust value) = fixed data (abso-
lute value) + set value of the SVC mode (relative value) +
set value of the ENG mode (relative value) + set value of
the USER mode (relative value)
. The fixed data is stored in IC74 (this IC is mounted in
the IC socket (CNI1) on the DCP-1 board), and the set
values of the USER, ENG and SVC modes are stored in
IC152 (on the DCP-1 board).
. The set values of the USER, ENG and SVC modes are
set to 0 when the unit is shipped from the factory.
Execute the DATA RESET of each mode to return to the
factory shipping data. (The adjustment is required.)
1. SVC mode
. The replacement boards for repair purpose supplied from
the repair parts center is adjusted at the factory. Howev-
er, due to the variability of respective products, perform
the adjustment using the SVC mode after the board
replacement, or when you require the fine-adjustment.
. When adjustment is performed using the SVC mode, the
values of items adjusted in the ENG mode and the USER
mode become 0.
2. Setup card
. The set values of the USER mode and ENG mode are
stored separately in the setup card.
. The set value at the factory is stored as fixed data. This
value may differ for each unit. The [fixed data + set
value in SVC mode] in each state must be made the
same when an identical setup card is used before and
after board replacement or between different units.
It is recommended to store the set values of the USER
mode and the ENG mode beforehand in the setup card
using the reference unit. Then perform adjustment using
the SVC mode for the unit after the board replacement is
performed or another unit, and download the stored data
from the setup card.
