a) AUTO ASPECT (Japanese Model only)
When the BKM-B11 is installed, the aspect ratio is
automatically switched by the identification signal at
the D terminal.
ON : Aspect ratio is automatically switched by the
identification signal
OFF : Automatic switching of aspect ratio is
prohibited.
Set the AUTO ASPECT item to the ON position
normally.
b) AUTO PLL SETUP
Sets enable/disable of automatic execution of the
PIXEL ADJUST function.
ON :When the AUTO PLL SETUP is set to ON,
the PIXEL ADJUST is automatically executed
when the main power is turned on or when the
input signal is switched. (Be noted that about
10 seconds are required to output the video
signal after switching the input signal when this
function is kept to the ON position.)
OFF : The automatic PIXEL ADJUST is executed
only when AUTO item of the user menu
PIXEL ADJUST is activated.
This function becomes valid only when the signal that
enables the PIXEL ADJUST is inputted to the
42B2/B2E
.
PFM-
Set the AUTO PLL SETUP item to the OFF position
normally.
Video Processor Adjustment
Refer to section “2-5. Video Processor Adjustment”.
(Perform the service menu adjustment of the video processor only when the specifications cannot be satisfied by section “2-5. Video Processor Adjustment”.)

PFM-42B2/42B2E
c) AUTO PLL PIXEL
Selects the functions that are automatically adjusted
when PIXEL ADJUST is executed.
ON : Both the TOTAL H PIXEL and DOT PHASE
are automatically adjusted.
OFF : Only the DOT PHASE is automatically
adjusted.
In the case that the
PFM-42B2/B2E
is used under the
environment where input signal contains much noise,
there are cases that the PIXEL ADJUST mis-operations. Therefore, set the AUTO PLL PIXEL to the
OFF position. In such a case, the TOTAL H PIXEL
can be adjusted only manually.
This function becomes valid only when the signal that
enables the PIXEL ADJUST is inputted to the
42B2/B2E
.
Set the AUTO PLL PIXEL item to the ON position
normally.
d) H/V SHIFT
Selects the method to control the horizontal and
vertical picture shift.
EDGE : When EDGE is selected, a picture is shifted
by changing the starting position when
reading data into memory. Using this
function, the entire area including blanking of
all pictures can be displayed by shifting. The
variable range of shifting is 1 horizontal and
vertical period respectively.
CAPT : When CAPT is selected, the picture that is
already written into memory is shifted by a
scan converter. Using this function, a picture
can be shifted as much as ± 50 % of a
picture. When a picture is partly lacked at an
end of a picture, the lacked portion of a
picture cannot be displayed.
Set the H/V SHIFT item to the EDGE position normally.
PFM-
e) VIDEO SHARP SW
Sets analog aperture ON or OFF.
The two methods are used for the aperture correction
of the video signals (NTSC/PAL/SECAM/NTSC4.43/
PAL60/PAL-M and YUV signal having horizontal
frequency of 15 kHz). These two methods are the
scaling filter and the analog aperture of the scan
converter.
ON : Both the scaling filter and the analog aperture
of the scan converter are used for aperture
correction.
OFF : Only the scaling of the scan converter is used
for aperture correction.
This function becomes valid only when the signal
(NTSC/PAL/SECAM/NTSC4.43/PAL60/PAL-M and
YUV signal having horizontal frequency of 15 kHz) is
inputted to the
PFM-42B2/B2E
.
Set the VIDEO SHARP SW item to the ON position
normally.
f) AUTO FT CANCEL
Sets the FT (field tearing) cancel circuit ON or OFF.
The
PFM-42B2/B2E
has the FT (field tearing) prevention circuit caused by the overrun of memory while it
is displaying the moving picture (video and DTV).
However, there can be cases that noise appears on
screen when the FT (field tearing) prevention is being
executed.
ON : The FT (field tearing) is cancelled in every
picture size and in every shift conditions as
long as the
PFM-42B2/B2E
is receiving the
moving picture. When this item is set to ON,
noise may appear only once after the size/
shift is adjusted. (Noise does not last long
but appears only once when the size/shift
adjustment is complete.)
OFF : The FT (field tearing) cancel circuit is
disabled. When OFF is selected, there can be
a case that the FT (field tearing) appears on
screen depending on the adjustment conditions of picture size/shift. However, the noise
due to operation of the processing circuit
does not occur.
Set the AUTO FT CANCEL item to the ON position
normally.

How To Edit The Preset Data
As shown in the illustration, the system controller contains
the memory area (i.e., Editing RAM) that is assigned only
for data editing. The source data that is used for editing
must be firstly copied to the Editing RAM. Edit then the
copied data as desired. Finally save the result of editing in
the specified preset area of the EEPROM.
(The illustration shows an example that the data in the
preset area No. 02 is once copied to the Editing RAM
where data is edited. The edited data is sent back to the
preset area No. 11 where the edited data is saved.)
