5.5 EEPROM
GY-HM150 has an EEPROM (MAIN board IC1005) for data stor-
age.
When the MAIN board or the EEPROM is replaced, initial value
data writing is required. Readjustment is also required because
the adjustment data is reset.
Using SSS (Service Support System) enables writing, reading
(backup), and changing EEPROM data.
5.5.1 EEPROM initial data writing
(1) Click [EEPROM Utility] on the SSS main screen.
(2) Click [Open].
(3) When the Initial and Original file navigator screen appears,
select the SSS folder. Selecting an Object Model automat-
ically displays files that conform to each CPU version.
(4) Click the Conformity file [M9H7-HM100**-MP-*.ROM].
(5) Click [OK].
(6) “Initial data for "GY-HM150**" was loaded on the map.” is
displayed. Click [OK].
(7) The initial data is displayed on the EEPROM Utility screen.
Make sure that the power dial of the unit is turned OFF,
then click [Write].
(8) Although the initial data is written, the adjustment data is
reset. Readjust the unit.
5.5.2 EEPROM data backup
EEPROM data can be backed up using SSS. The backed up EE-
PROM data can be rewritten in the unit.
(1) Click [EEPROM Utility] on the SSS main screen.
(2) When the EEPROM Utility screen appears, click [Read].
Fixed data Data that not change by CPU.
(Model code, etc.)
Adjusting data Data that is changed by adjustment.
(Adjustment data)
No Fixed data Data that may be changed by CPU.
(Focus/Zoom position memory, etc.)
Default setting data Data that is changed by usage
(Menu setting, emergency data, etc.)
Doctor data Doctor program (Data that not change.)
PE data Data that is used during production.
Caution
• Before starting EEPROM data writing, be sure to turn OFF
the power dial of the unit.
• The initial value data is reset, except the fixed value and the
doctor program. Therefore, it is necessary to readjust SEC-
TION 4.
• When the backup data writing of EEPROM, the initial value
data need not be written.
