ËImproving the Z9000U units
(Program version-up for HTPC (Home Theater PC) compatibility, performance upgrading and lip
synchronization improvement)
The Z9000U units have been improved in the following 3 points. These improvements can be
confirmed by looking at the program versions.
Program version and PC interface version
z Z901819 and Z901905
(CPCI0051CE01)
x Z901927
(CPCI0051CE05)
c Z901Z25 -
(CPCI0051CE05)
To implement the above improvements from Level-z to Level-c, it is necessary to update the PC
interface board programs, modify the hardware, and change some parameter settings. There is no
need to replace the PC interface board itself. If this board is replaced, however, the background
setting must be additionally readjusted.
To get the Level-z unit compatible with HTPC, just update the programs. To upgrade the Level-
xunit to Level-c, update the programs and make some readjustments. All these are discussed
below.
Upgrading from Level-z to Level-c
1) Checking the unit
» Select "STATUS" on the menu screen and look at the right bottom of the screen to check the program
version. If the version is "Z901819" or "Z901905", take the following procedures.
2) Jotting down the process parameters.
» Note down the existing settings specified below because there may be a problem during the
reprogramming. Your notepad can be used to confirm the settings after the reprogramming.
(1) Power on the unit and call the process mode.
To do so, use the keys on the remote controller or on the unit. Press the keys "INPUT → UP →
DOWN → ENTER → ENTER → MENU" in this order. Or just press the S001 switch on the main
PWB.
(2) Select "A/D, DLP and DTV" in this order on the process menu. Write down the following parameters.
A/D : A/D converter input setting
DLP : Background setting
DTV : Component mode A/D setting
(3) Exit from the process menu. Press the keys in the same order as for entering this mode.
