CR 1212 16
Chapter 4: Operating Characteristics and Functions
The CR 1212 includes a variety of operating characteristics and functions that can be
controlled with commands from the host. For example, define:
Report flow
Tablet resolution
Tablet origin location
The tablet accepts commands from the host at any rate, except in a few situations. So that
the CR 1212 is operable upon arrival at your facility, it is set to predefined default settings.
The unit defaults to these settings each time you turn on the tablet or issue the Reset
command. A summary of the defaults appear in the Reset command section and in
Appendix B
.
Section A: Controlling the Report Flow
The primary functions that control the report flow are Point, Remote Request, Stream and
Switch Stream modes. The secondary functions are Report Rate and Increment Mode.
Bit Pad One configurations: Each time the tablet is turned on or issues the Reset
command, it defaults to Stream Mode.
CR and Bit Pad Two configurations: Each time the tablet is turned on or issues the
Reset command, it defaults to Remote Request Mode.
Bit Pad One reports have no proximity bit. CR and Bit Pad Two reports have a
proximity bit.
Each report has flag bits. These bits identify the stylus/cursor buttons that were
activated when the report was issued.
There is a distinction between
scanned
reports and
issued
reports. The tablet reads
the stylus/cursor location 110 times each second. It stores the scanned reports in
an internal buffer. Although the tablet scans continuously, it only issues reports to
the host as dictated by the selected mode, such as Point Mode. The reports sent to
the host are called
issue reports
