8. Factory district setup
The following are factory district setups, users are recommended to
make these setups under the guidance of manufacturer’s technicians,
any improper setting or operation may result in abnormal happening to
the processor.
Item 21: “Device ID”
This item is used to number LVP605 while controlling several
processors by RS232. The number scale is from 1 to 255.
Item 22: “ADC Calibration”
After inputting a analog signal to the video processor whose white
balance has not been calibrated, the picture on the display may appear
some bad phenomena, such as color cast, extreme-darkness. LVP605
can solve the above problems by automatically calibrating white
balance based on the input analog signals（CVBS、S-Video、YPbPr、
VGA）. Operating procedures:
Switch to the corresponding analog input signal, enter Item No. 21
“Device ID.” after the processor detects input signals and exports the
signals to the display, press “V1” for 5 times, then press “↑” to shift to
Item 22 “ADC Calibration”, press knob to calibrate white balance.
Caution: The white balance of all video processors has been
calibrated using standard signals in the factory, please don’t set
this item unless necessary!
Item 23: “De interlace”
When CVBS/S-Video/HDMI/SDI signals are interlace input
formats (e.g.: 1080i) and used as PIP, due to limits of the processor,
tremble may take place, it can be dispelled by setting the option “De
interlace”. Operating procedures:
enter Item No. 21 “Device ID”, press “V1” for 5 times, then press
“↑” to shift to Item 23 “De interlace”, turn knob to select “ON”, and
press knob to make it valid.
