If left in direct sunlight for an
extended time, the display can get
hotter than its maximum operating
temperature and darken. Shade it as
much as possible from direct
sunlight
The PTC-2124 contains a 1/4 VGA, transflective,
monochrome display with an EL panel backlight.
A transflective display uses reflected ambient light to
produce viewable display images. It is ideal for use in
outdoor applications. For indoor use, the PTC’s
backlight may be used to optimize the display
visibility in low lighting or under fluorescent lights.
The PTC-2124 features a resistive touch panel
digitizer, which is mounted above the display. The
digitizer enables the PTC to recognize data entered
with a stylus. It also has a palm reject feature, which
prevents accidental activation of the unit by casual
hand or finger contact.
Entering data
Data can be entered into the PTC-2124 in a variety of
ways. You can use your finger or the PTC’s stylus to
select options on the PTC’s screen; scan 1D bar codes
with an optional laser scanner module; or receive data
through an optional internal radio.
With your finger or a stylus
As a pen-based computer, the PTC-2124 is ideal for
forms-based data gathering. Use your finger to select
menu options or the PTC’s stylus to write in the fields
of a form displayed on the PTC’s screen or to check off
items on a list. You may also have the option to
capture signatures onto electronic forms (for example,
when a delivery is made or an order is placed).
