Sync Type
The Sync Type option sets the synchronization signal type of the output format. Press the Up or
Down button to show the current sync type. Press the same button again to move to the next sync type.
Currently, the iScan supports seven sync types:
• Bi-level bi-level sync on green/luma
•
Tri-level tri-level sync on green/luma
•
CSync Composite Sync (on the H sync BNC connector)
• H+V+ Positive Hsync and Positive Vsync
• H+V- Positive Hsync and Negative Vsync
• H-V+ Negative Hsync and Positive Vsync
•
H-V- Negative Hsync and Negative Vsync
Color Space
The color space parameter sets the color space of the output format. After highlighting ‘Color Space’
in the OSD, press Enter or ? to show the current color space. Press the same button again to select
the alternate color space. Two analog color space options are supported: YPbPr (default) and RGB.
Two digital color space options are supported: RGB (default) and YCbCr (both 4:2:2 and 4:4:4).
Output Level
The output level setting allows the user to specify the levels of the output signal, either Video
(16-235) or PC (0-255). Some displays are expecting to receive the increased dynamic range of a
PC signal, and will show an image that looks “washed-out” if this improperly set to ‘Video’.
Framerate Conversion
This parameter enables framerate conversion. There are two sets of controls, one for 50Hz input
sources and one for 60Hz input sources.
For 50Hz sources, if the original source material is progressive at 25Hz (uses 2:2 pulldown), the out-
put framerate can be source locked at 25Hz, 50Hz or 75Hz. The 25Hz setting outputs each original
25Hz frame, the 50Hz setting repeats each original 25Hz frame 2 times, and the 75Hz setting repeats
each of the original 25Hz frames 3 times. You can also set the output frame rate to a specic value
(unlocked mode).
For 60Hz sources, if the original source material is progressive at 24Hz (uses 3:2 pulldown), the out-
put frame can be source locked to 24Hz, 48Hz, 60Hz or 72Hz. The 24Hz setting outputs each original
24Hz frame, the 48Hz setting repeats each original 24Hz frame 2 times, while the 72Hz setting re-
peats each frame 3 times. As with 50Hz sources, you can also set the output frame rate to a specic
value (unlocked mode).
Press p or q once to see the current input rate. Press the same button again to switch input rate.

For 50 Hz input sources, the available settings are:
• 25Hz Lock source locked 25Hz
• 50Hz Lock source locked 50Hz
• 75Hz Lock source locked 75Hz
