Roll-Up III 4
Introduction
Roll-Up III belongs to a class of computer input devices called graphic tablets, or
digitizers. A digitizer is an electronic tablet work surface. The position of a transducer, a
handheld cursor or stylus, on the work surface of the Roll-Up III is converted – digitized –
into data for computer processing. Data output from the Roll-Up III digitizer is in the form
of an X/Y coordinate pair that pinpoints the location of the transducer on the tablet
surface. The Roll-Up III is a specialized graphic digitizer that is specifically designed to be
portable, so it can be taken to the job site.
NOTE: Roll-Up III uses an electrostatic technology for digitizing with blueprints and
nonconductive inks. If you are using black line drawings with conductive ink, the Super L
Series Digitizers are more appropriate.
Roll-Up III works with many graphic, CAD and estimating applications. These applications
use the digitized data from the Roll-Up III to:
 Determine the dimensions of objects on drawings and blueprints
 Move the pointer on the display screen
 Create and manipulate objects in a graphic composition
 Trace a drawing, or other source material to create an image on the display screen
 Select commands or functions from an application menu placed on the tablet
surface
 Select items from a pull-down menu on the display screen
In order to send data from the Roll-Up III to your digitizing application, the digitizer must be
physically connected to your computer, and it must be able to transmit the data in such a
way that the digitizing application recognizes and understands it. Before you set up the
Roll-Up III, you should determine:
 The requirements of the digitizing software application being used
 Whether your digitizing application requires software drivers to communicate with
the Roll-Up III
 Hardware communications connection (Serial or USB) you will be using between
the Roll-Up III and the computer
