| The
AKT/ABT series keypad encoders were designed to provide a
low-power solution for converting key presses into RS-232
compatible data.
Each key on the AKT keypad is
assigned to an ASCII character code.
For example, pressing the top-left button on the AKT generates
the ASCII character code 0. The bottom-right button on
the keypad generates the ASCII character code 15.
Jumper selectable ASCII
character codes allow the encoder to generate ASCII characters
0 to 15 or 16 to 31. If you need other ASCII character
codes, let us know, we carry all sets from 0 to 255 in
increments of 32.
The AKT/ABT has 3 outputs
types: Infrared RS-232 (requires our
IRTR to receive data), O.C. RS-232 for connecting several
keypads to a single serial port (requires
RSB serial booster), and logic-level RS-232 for output to
PCs and the Basic Stamp (not compatible with the Macintosh).
Two versions are offered to
assist you from prototyping to production. For
prototyping, the AKT provides a convenient solution because of
its integrated 16-button keypad. When you are ready for
production, the ABT is ready to interface to any industry
standard (pre-manufactured) keypad, up to 16 keys.
Both versions are low power and
will run off 2 AA batteries for several months. No need
for a voltage regulator or power switch.
INFRARED RECEIVER NOT
CURRENTLY AVAILABLE
Requires the RSB Serial
Booster when connecting more than one keypad to a single
serial port.
