Code

Mode of Operation

Mode Control Commands

BXnnnn

Set the left edge location of the output video window in either pixels, or in percentage of
the frame width by appending the '%' symbol.
The window must always fit within the video frame. The DX-2200 will limit the value
entered with this command to keep the window within the frame.

BYnnnn

Set the top edge location of the output video window window in either pixels, or in
percentage of the frame height by appending the '%' symbol.
The window must always fit within the video frame. The DX-2200 will limit the value
entered with this command to keep the window within the frame.

BWnnnn

Set the width of the video output window in either pixels, or percentage of the video
frame width by appending the '%' symbol. The value 9999 has a special meaning and
causes the width to be calculated automatically from the height to maintain the aspect
ratio.
The DX-2200 will always limit the window size to prevent it being larger than the video
frame.

BHnnnn

Set the height of the video output window in either pixels, or in percentage of the video
frame height by appending the '%' symbol. The value 9999 has a special meaning and
causes the height to be calculated automatically from the width to maintain the aspect
ratio.
The DX-2200 will always limit the window size to prevent it being larger than the video
frame.

Reset size and position to defaults

Where ‘nnnn’ can be a number of pixels between one and four digits in length, or be followed by a ‘%’
sign to specify a percentage of the output frame size, eg ‘50%’. When specified in %, the value can be
an integer between 0 to 100.

Table 8: Text Inserter with Scaling Zoom SERIAL Command Codes

Mode of Operation

Mode Control Commands

ZSF

Set the zoom function to be controlled in percentages by specifying center position and
zoom factor. This is the default control mode. After setting this mode, use the ZSCX,
ZSCY and ZPnnn commands to control the zoom function.

ZSW

Set the zoom to be controlled in pixels by specifying left edge and top edge position,
and the width and height. After setting this mode, use the ZSLX, ZSLY, ZSLW, and
ZSLH commands to setup the PiP window.

ZSCXnnn.d
ZSCYnnn.d

Set the center location of the Zoom, where nnn.d is a number from 0 to 100 with up to 1
optional decimal place. This number represents a position in the video source to use as
the zoom center point, specified in percent of the video width (ZSCX) or height (ZSCY).
The resulting zoom window can never extend beyond the edge of the video source. The
DX-2200 automatically restricts the values to a valid range.
The default setting is 50% for both horizontal and vertical, meaning the video is zoomed
in toward its center.
These commands only has an effect in center / zoom control mode. See the ZSF
command.
