Annotation
This section of the manual discusses on screen annotation and is in four sections:
• USB and RS-232 Driver Configuration
• USB Port Connections
• Touchscreen Calibration
• Annotation Overview
The 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, and a standard keyboard and/or mouse. The touchscreen
panels can be connected by RS-232 or USB, and device drivers can be uploaded to ensure
compatibility with the Annotator. For a full list of compatible panels visit
www.extron.com. Contact Extron if the device you wish to use is not listed.
USB and RS-232 Driver Conguration
USB and RS-232 driver conguration is possible using the Signal Processing Products
Control Program. The Device Module Configuration option allows you to configure a
touchpanel so that it can be used with the Annotator.
Connect a touchpanel device to either of the USB ports or, using a NULL RS-232 cable
only, connecting the touchscreen to either of the two rear panel RS-232 ports.

To load a touchpanel driver:
1. Open the SPPCP program on a PC connected to the Annotator by an IP connection.

Device Module Manager window.
