Command
Code
Mode of Operation
LnPxxxx,yyyy
Set the x and y position of the overlay for Layer n.
xxxx and yyyy are numbers between 1 and 4 digits in length.
The overlay must always fit completely within the output video and the position
specified in this command is automatically adjusted to prevent the overlay
extending beyond the edges of the video.
Therefore, if the overlay is at the default size (the same size as the output
video) it can only be positioned in one location and this command will have no
effect. The overlay can only change positions if the size has been reduced to
be smaller than the output video size.
nnn is the layer number(s), See **
LnPXxxxx
Set the x-direction position only for overlay layer n.
nnn is the layer number(s), See **
LnPYyyyy
Set the y-direction position only for overlay layer n.
nnn is the layer number(s), See **
LnPM1
Set the position coordinates for layer nnn to be specified as top-left corner of
the overlay
nnn is the layer number(s), See **
LnPM2
Set the position coordinates for the layer nnn to be specified as center position
of the overlay.
nnn is the layer number(s), See **

The DX-2200 supports Digital Zoom of the video input channels. Zoom can be
specified independently for the selected and non-selected inputs. The zoom
function operates by selecting a region of the input video for processing instead of
using the full size video. The selected region is referred to as the zoom window in
this manual. The scaler in the DX-2200 will scale up the selected zoom window to
the size needed for the output video, resulting in a zoomed in view. The zoom
function allows for increasing the size of the video above full size (100%). It is not
possible to use the zoom function decrease the size of the video.
T
he Digital Zoom Commands in this section begin with either ‘ZS’ to refer to the
selected input,
or with ‘ZP’ to refer to the non-selected input. The following section
refers
to ‘ZS’ commands only, but the same applies for ‘ZP’ commands.
Two
methods of setting the zoom are provided. The ‘ZSP’ command enables
setting the zoom as center position and zoom percent. This is the default zoom
control method. The
‘ZSnnn’ command specifies the zoom as a percentage from
100% to 800%. The
‘ZSCXnnn’ and ZSCYnnn’ commands specifies the zoom
window center x and y position respectively as a percentage of the video size in
the range from 0% to 100%. The parameters can include up to 1 decimal place.
The zoom window must always fit within the input video. The DX-2200 will adjust
the zoom position as required to make the window fit.
For example, if the zoom is set to 200%, then the zoom center position can be
moved between 25% and 75% of the video size in both the x and y directions.
