SIGMA LBA-708 - Manual (Page 152)

If your camera has fewer data output signals than the LBA has inputs, then use the upper most
data inputs, starting at VD11, and cut open the following jumper traces:
• For an LBA-500PC with a 10 bit digital camera, cut open E7 and E8.
• For an LBA-500PC with an 8 bit digital camera, cut open E7, E8, E9 and E10
• For an LBA-400PC with an 8 bit digital camera, cut open E9 and E10.
Note: Jumper cuts are made between square shaped circuit pads labeled with “E#” designators. An
Exacto knife with a sharp blade is recommended for making these cuts. If you are unsure how to go about
performing these small surgical like operations then please call Spiricon’s service department and we can
walk you through it.
7.3 Digital Camera Advanced Timing Setup
The following Camera, Advanced settings; Transfer Mode, Scan Mode, Horizontal Start,
Horizontal Size, Vertical Start and Vertical Size, must be correctly set in order to capture
and display the data transmitted from your digital camera. These settings are best
accomplished by making a few good guesses and then modifying your results by trial and error.
You will need to know:
• Is your camera operating in an Interlaced or Non-Interlaced (Progrssive scan) mode?
• If your camera is interlaced, does it use a Frame transfer style detector?
• What are the total number of HSYNC’s (lines or rows) that your camera outputs per
VSYNC (or frame, if interlaced) of video?
• How many of those rows are black, and how many contain real data, and where are
they?
• How many total pixel clocks are output per HSYNC (line or row) of data?
• How many of those clocks have black data, and how many contain real data, and where
are they?
7.3.1 Transfer Mode
If your camera is an interlaced or pseudo interlaced frame transfer style set the mode to
Frame. If your camera is a non-interlaced (progressive) scan style that uses either Interline
or Full-frame transfer style imagers set the mode to Interline. For most CMOS, X/Y and line
scanning camera set the mode to Line.
7.3.2 Scan Mode
If your camera is interlaced select Interlaced. If non-interlaced, or progressive scanned,
choose Non-interlaced.
7.3.3 Vertical Start
This value must be an even number. Enter the row where video data begins. If your camera
is non-interlaced, and outputs a total of 300 rows, where the first 24 rows are black followed
