8. AD DATA CHECK
This menu is used to display the A/D conversion value of the microprocessor which detects panel keys of this unit and
protection functions in using the sub-menu.
When KEY menu is selected, keys become non-operable due to detection of the values of all keys. However, it is
possible to advance to the next sub-menu by turning the INPUT of this unit.
* Numeric values in the figure example are for reference.
P1/P2 (Power supply voltage protection detection)
Power supply voltage protection value
(Normal value: P1: 190 to 380, P2: 260 to 450)
P1: Detects +12FL, -20D and +3.3.
P2: Detects Vp, +20D, +5FL and +10T.
* If Px is out of the normal value range, the protection function works to turn
off the power.
(Reference voltage: 5V=500)
DV/DK (DVD/DOCK)
DV: DVD power supply detection.
(Normal value: 240 or more)
DK: DOCK type detection
(Reference voltage: 5V=255)
DESTINATION
The destination of this unit is displayed.
Destination for AD port (pin no. 97 of IC11) pull-up resistance 10k-ohms.
P3/DC (Power supply voltage protection detection/
Power amplifier DC protection detection)
P3: Amp DC protection
Detects 6R3V, V+5V and 3R3.
(Normal value: 160 to 240 (select input DVD), 0 to 30 (select input other))
* If Px is out of the normal value range, the protection function works to
turn off the power.
(Reference voltage: 5V=500)
DC: Power amplifier DC (DC voltage) output is detected.
(Normal value: 180 to 320)
(Reference voltage: 5V=500)
