A programmable PS/2 keyboard encoder for interfacing keypads and switches to the computer!
The LP24 Keyboard Encoder interfaces keypads, switches, or other input devices to the computer's PS/2 keyboard port to generate keystrokes in response to input activations. The LP24 features 24 programmable pins each of which may be programmed as a Row or Column in a scanning matrix. This feature allows for the direct connection of off-the-shelf keypads to the .100” centered pins that have the capability of accepting most membrane switch tails as well as a wide variety of standard connectors. The ability of each pin to be configured as a Row or Column in the matrix eliminates the need for any special wiring between a keypad and the LP24 header. The LP24 will scan any size matrix up to a 12 Row x 12 Column for a total of 144 inputs.
Each switch position in the scanned matrix can be programmed to emulate any standard keystroke, including keystrokes modified by Shift, Alt, or Ctrl. (EX: Ctrl+F1). Once programmed, the configuration is stored on the LP24 in non-volatile memory. The unit is programmed via the PS/2 keyboard port of the computer using a standard Male to Male 6 pin miniDIN (PS/2 style) cable.
All power for the LP24 is taken directly from the computer’s PS/2 keyboard port, no additional voltage supply is needed. Because the LP24 emulates a standard PS/2 keyboard, no special drivers are required. The LP24 will function as the only keyboard on your computer or in addition with other USB keyboards, PS/2 keyboards, or other devices attached to your computer.
A printed user manual and disk containing computer applications are provided for the user to configure the LP24. Configurations developed using the included programs may be saved to the unit as well as to the computer.
