| The KE-8 Keyboard Mimic provides an easy and straightforward method of
interfacing contact closures, such as pushbuttons, to a personal computer.
Connection to the computer is via the standard PC keyboard connector. Inputs
for eight pushbuttons are provided. When a contact is made, the keystrokes
programmed into the KE-8 are transmitted to the PC. As far as the PC is
concerned, this data is indistinguishable from that provided by the standard
keyboard. If illuminated pushbuttons are used, the KE-8 will flash the lamp
briefly. This is useful in that it provides visual feedback. The KE-8 is
programmed by connecting it between the keyboard and the PC. The red Program
button is pressed, the desired keystrokes are typed, and the desired button
is pressed. Upon pressing one of the eight buttons, the keystrokes may be
disconnected; the PC will boot and operate with just the KE-8. |
