Eeprom Setting Mode - Pioneer avr-w6100 Service Manual

6.4 EEPROM SETTING MODE

[Preparation]
The operation is possible only with the remote control (CXB9056) supplied with the AVR-W6100,
which uses remote control codes for the rear monitor.
Any key inputs from the main unit are not acceptable.
A
[Operations]
To enter the setting mode, while keeping the EPRTEST terminal
(probe land EPRTSTA) at "Low", turn on the power.
To switch between the adjustment modes, use the MENU button.
Flicker adjustment mode
Line adjustment 1 mode
Line adjustment 2 mode
Dimmer parameter setting mode
[ ↑ ↓ ] button: Used to select a desired adjustment item in each mode
[ ←→ ] button: Used to adjust the selected item
Notes:
1) The setting values are written in the EEPROM,and then the read-out data is displayed
on the screen. WRITE and READ operations are processed by the block data of 16 bits.
The total bits for the settings depend on adjusting items.
2) For CS (Check Sum) items, when the settings are changed, the CS value is written in
8 bits by applying the exclusive OR (XOR). The CS value is first written in the EEPROM,
B
and then the read-out data is displayed. If the written data is different from the read-out data,
the letter color for the read-out data is changed.

1) The Bank 1 (with memory protection) items can be adjusted only in the line adjustment modes.
2) For the Bank 2 (without memory protection) items, the initial values are written in the line
adjustment modes, and then are adjustable by the user.
