Overview of the PTC-2124
The PTC-2124 is a rugged, SC400-processor-powered,
PC-compatible, pen-based portable teletransaction
computer (PTC). It is used to collect, store, and
transmit data. Unlike personal computers, which rely
primarily on a keyboard for data entry, the PTC-2124
uses its screen as the main input device.
In general, operate your PTC by using your finger or
the supplied stylus to select choices from menus. The
stylus may also be used to write directly on the screen
to fill in forms or check off boxes. The actions you take
depend on the application program your organization
has developed for its specific needs. See the manuals
or instructions that your organization provides for
details on your application.
Through its pen operating environment, the PTC
recognizes the touches or written letters and numbers
on its screen and translates them into a form that can
be used and stored in the PTC.
Processor
The PTC’s 100-MHz AMD Elan SC400 microprocessor
is fully IBM PC compatible. It provides exceptional
processing speed and is designed for low power
consumption.
100 MHz is the default setting. The PTC can also be set to operate at 33 or 66 MHz to
reduce power consumption. To change the processor
speed, press the F2 key from an attached keyboard
during boot-up to access the CMOS setup. Then select
the Advanced option and press the + or – key to set
the speed to 33, 66, or 100 MHz.
