Source number
The source number of a non-active source can be changed to any other source number. This makes
it possible to create a file for future source numbers.
Clamp position
Clamping determines the black level of the signal. The clamp pulse can be related to the leading or
the trailing edge of the sync pulse. Use the
ENTER
key to toggle between [leading] and [trailing].
Clamp delay
The time between the leading edge of the clamp pulse and the locked edge of the sync pulse. Can be
any value between 0 and 255. Change the value by pushing the cursor key
↑
or

.
Clamp width
The width of the clamp pulse can be any value between 0 and 255. Change the value by pushing

Example for
Clamp position
[trailing]
Field select
Default [both]
The field select is only used for interlaced images. One frame of an interlaced image contains two
fields, an even and an odd field. The choice exists to project [both] fields on the screen or only the
[even] or [odd] field.
Use the
ENTER
key to toggle between [both], [even] and [odd].
If the active Stereo Compatibility Option is installed, the field select parameter will be changed
into a [left] and [right] selecting parameter which will be selectable for stereo files. This setting
will then be saved in the active image file.
Vertical refresh
[sync/async]
The way of updating the image information on the DMD panels. Not available for PAL-NTSC-SECAM
sources. Where this option will be displayed in gray.
•
For sources with a vertical frequency up to 62 Hz : the vertical refresh rate is the same as the
vertical frequency of the incoming source. This is a necessity to project moving images without
’motion artifacts’. For stationary images with a vertical frequency up to 62 Hz it is still possible to
use asynchronous refresh.
•
For sources with a vertical frequency higher than 62 Hz : the vertical refresh is different than the
vertical frequency of the incoming source. Synchronous refresh cannot be used.
Vertical Sync Polarity:
[leading] or [trailing]
The vertical refresh can be synchronized with the leading sync edge or trailing sync edge. Default on
[leading]. Toggling to [trailing] is only necessary for special applications where the trailing edge of the
sync signal has to be taken as a reference. Use the
ENTER
key to toggle between [leading] or [trailing]
