selected by installing jumper PS1/2 (F2040). The _BLANK input must also be in
LOW state. For more information of this mode contact Planar.
To reduce the input data frequency in NORMAL mode the Video data can be
input two bits per clock cycle. The two data inputs are organized so that the
data for the odd columns, numbered from left to the right at the viewers side,
is input at the TVID (J1/ pin 7) and the data for the even columns at VID (J1/ pin
15). The two bit parallel mode is selected by installing jumper 3 of the pin strip
PS1.
The brightness of the display can be adjusted (appr. between 10 and 100%) by
an external 50 logarithmic potentiometer between the LUMPOT1 and
LUMPOT 2 inputs (J2/pins 1 and 2). The control function is done by feeding a
small DC current signal via the external potentiometer from LUMPOT1 (+5V
reference voltage) to LUMPOT2. If the two inputs are left disconnected, the
brightness is at its maximum level.
The operation of the display can be easily checked without any external
signals by the self test function.
Insert Jumper 1 in pinstrip PS2.
Connect power to the display.
All pixels of the display will be lit with the exception of the first half of the
topmost row.
Mounting of the display should be done using the M3 insert nuts on the four
corners of the plastic assembly support or the four holes in the FRA frames.
Note that because all four mounting points are internally connected to signal
ground care should be taken to avoid grounding loops.
Before handling the display, necessary precaution must be taken to prevent
application of static charges on the display from the operator or tools.
The display is made of glass material and should be handled with proper care.
Do not drop the display or allow hard objects to strike its surface.
