PS2ADPT is a 2.6" X 1.7" X 0.8" module
which provides a complete interface to a standard IBM PC PS/2 keyboard handling the 2-wire
keyboard protocol, and converting all the default SCAN SET 2 keycodes to simple ASCII characters.
This allows non-PC systems using low-end microcontrollers, or
powerhouse microcomputers to use inexpensive PC keyboards without dealing with the
complexities of multiple keycodes in real-time. PS2ADPT handles
all the real-time response requirements of the keyboard protocol and even transparently
manages the keyboard LEDs (CAPS LOCK, NUM LOCK, SCROLL LOCK) independent
of the host computer. The host receives just the ASCII characters as printed on the keyboard's keys with any modifiers such as the SHIFT keys already applied.
auto-detects the presence or absence of the keyboard on power up and
reports the condition to the host.
Full manual is available here. A diagram of all 102 keys and their corresponding serial-character outputs is available here.
|PS2ADPT-XXX is available with power source and RS-232 options to provide the flexibility to mate to a variety of systems without additional adapters.|
