3-1.
Necessary Items
One 3.5-inch floppy disk (Parts No. 3-702-760-01)
RS-232C cable (Dsub 9/MiniDIN 8) (Parts No. 1-690-391-21)
IBM/PC or compatible (MS-DOS Ver. 5.0 or above)
3-2.
Purpose
This service kit can be used for the following adjustments.
1) Color-adjusting the DSC-1024HD
2) Loading the geometry factory setting data of the DSC-
1024HD
3) Checking the main CPU operation of the DSC-1024HD
4) Passing digital circuits
These adjustments are used in the following.
1) This adjustment is necessary when a signal gain is changed
due to device replacement, etc. When the color or luminance
of output signal is incorrect, perform this adjustment.
2) In the DSC-1024HD, the geometry factory setting data
which displays an image with correct size and correct posi-
tion when a preset signal is input is stored in the EEPROM.
If this data is lost due to the CPU or EEPROM replacement,
load this data.
3) This function displays an operational condition of the CPU
of the DSC-1024HD. This allows the CPU operation to be
detected when the CPU is normal, and parts which need to be
repaired can be located.
4) This function is useful for discriminating failure between the
decoder and encoder analog circuits when the DSC-1024HD
does not operate correctly. However, note that format con-
version (timing conversion) is not carried out in input/output
during operation.

Setting
Connect a RS-232 cable (Dsub 9) to COM1.
Connect the MiniDIN 8 of the RS-232 cable to CN252 of the
unit.
Installing software
The following files are provided in the 3.5-inch floppy disk.
DSC.EXE adjustment program
Preset data for HD10. PRE microcomputer V1.0
SCH.EXE adjustment program
Copy these three files to the same directory when installing these
on a PC hard disk.
Note: Although the color data of this program is saved in a PC
file, it can be saved only in the directory with DSC.EXE.
The color data or preset data saved in the PC can be read
for transfer to the unit. However, a file used for this proce-
dure should be kept in the directory with DSC.EXE.
When performing DSC.EXE, this should be carried out
from the directory with the DSC.EXE.

Operation
Access
When MS-DOS prompt appears, type C : >DSC.
Adjusting Software (DSC. EXE) screen
Use
↑
or
↓
key to select an item, and press the ENTER key to
determine the data changing mode of items.
Use
←
or
→
key to change data, and press the ENTER key to
determine the data.
Data can also be changed by typing numerals directly. (Use the
ENTER key to determine the data.)
The following functions are also provided.
ALT + X
Ending DSC.EXE
“YES”
: Ends
“NO”
: Returns
ALT + F
Saving and loading data to a PC file
“LoadColorData”
: Transfers data from a PC file to DSC.
“SaveColorData”
: Saves a DSC data to a PC file.
“LoadPresetData”
: Transfers preset data to DSC.
“Cancel”
: Returns
ALT + S
Saving data to EEPROM
“SaveColor”
: Saves a COLOR_NDX table data to
the EEPROM.
“Init EEPROM”
: Initializes the EEPROM.
(All adjustment data are eliminated.)
“Cancel” : Returns
ALT + R
Reads the unit data again.
ALT + C
Copies a color data (Note)
“YBR V3
→
YBR V2”
“RGB V3
→
RGB V2”
“YBR V3
→
Y/C (NTSC) V1”
“Y/C (NT) V1
→

“Comp (NT) V1
→
Comp (NT) V2”
“YBR V3
→
Y/C (PAL) V1”
“Y/C (PAL) V1
→
Comp (PAL) V1”
“Comp (PAL) V1
→
Comp (NT) V2”
“Cancel” : Returns
ALT + T
Setting test mode
“Digital Pass”
: Outputs an input signal without passing
through the digital section.
A repair can be made by disconnecting a
digital section and an analog section, be-
cause of a direct connection from ADC to
DAC.
(The input/output signal timing becomes
same)
“Memory Check” : Displays flame memories A to D sepa-
rately.
The selected memory data are output by
the amount of 4 lines, and the other
memory data is not output, and therefore
the memory can be identified if de-
stroyed.
“Cancel”
: Returns
