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 lead-
ing or the trailing edge of the sync pulse. Use the

Clamp Delay
The time between the leading edge of the clamp pulse and the locked edge of the sync pulse.

Field Polarity
The field polarity function is used for interlaced images. Both rasters of the image could be
shifted in a wrong way (double lines are visible in the image). This can be corrected by forcing
the field polarity to [

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 [

* For sources with a vertical frequency up to 60 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 60 Hz it is still possible
to use asynchronous refresh. When loading Pal, Secam, NTSC-files the synchronous mode is
default, for all other sources below 60 Hz asynchronous mode is default.
