Page: 6 / 48

Bit Pad Two 6
data tablet is in Absolute Mode . Reports are in relative coordinates when the data tablet is
in Relative Mode .
Absolute and Relative modes are two of the Bit Pad Two’s many operating characteristics.
Other operating characteristics govern when reports are issued; how fast they are issued
and the tablet resolution.
The operating characteristics can be set by commands from the host or by switches. The
switches, slide or rocker, are grouped in banks of eight per DIP switch. The DIP switches
are located on the printed circuit board inside the tablet.
Also, established by switch are the data tablet’s configuration parameters. These
parameters specify the data communications, such as CTS handshaking and baud rate, and
the data format.
Chapter 2: Configuration Parameters
For successful communication between a Bit Pad Two and its host, the hardware interface
and configuration parameters must be compatible. The hardware interface is RS-232C.
The configuration parameters are:

Proximity transmission
 Remote control

Baud rate
 CTS handshaking

Report format and cursor output codes
This chapter describes the alternatives available for each of the configuration parameters.
The parameters are switch-selective.
Appendix D Quick Reference Sheet of Commands and
Switch Settings summarize the switch settings and defaults that the factory normally uses.
Section A: Proximity Transmission
The data tablet can be configured to:

Transmit reports only when the cursor or stylus is in proximity.
 Transmit reports regardless of whether the cursor or stylus is in or out of proximity.
If the data tablet is configured the second way, reports issued from out-of-prox will reflect
that state with a special bit or character. Reports in the binary format have a bit assigned
