Toggling Window Sequences Using a Software
Trigger
Purpose: To allow quick activation of new window coordinates, the camera
allows you to preset one sequence of window coordinates. These
coordinates wait for a trigger and because they have been
preprogrammed, the new window is activated extremely quickly.
This command loads a new window sequence.
Syntax:
wss m
Syntax Elements:
m
Window sequence trigger where changing from 0 to 1 (or vice
versa) toggles the current window sequence being used.
Related Commands:
wts
Example:
wss 0
Notes:
• There is a delay between the issue of the wss command and the
time when the new window sequence is triggered (Figure 16)
• When toggling windows, the camera discards the first frame
read out after the toggle. This prevents the camera from
sending out erroneous data.
• Upon power up or reset of camera, the camera assumes that a
wss 0 has already been executed
