On Screen Annotation
The Extron Annotator is a high performance, hardware-based annotation processor
for video and computer-video sources. Annotating over motion video or still
images is possible using common touchscreen panels, as well as any standard
keyboard and/or mouse. The touchscreen panels can be connected by RS-232 or
USB. An RS-232 touchscreen device driver can be uploaded to ensure compatibility
with the Annotator. A number of touchscreen panels are supported.
For a full list of compatible panels visit
HelpLine if the device you wish to use is not listed.

configure a touchpanel so that it can be used with the Annotator.
Using a NULL RS-232 cable only, connect the touchscreen to the Annotator via
either of the two rear panel RS-232 comm ports.
