ABSTRACT:
A hand-held keyboard test unit includes an enclosure that fits easily within one hand, a keyboard connector for receiving a keyboard connector, a controller programmed solely to execute tests of the keyboard, a digital display to indicate the status of the test and provide instructions to the test unit operator, and a switch to initiate the test sequence. The controller causes the keyboard to execute its self-test routines, transmits and verifies responses to standard system unit commands to the keyboard, and conducts a key closure test for each key on the keyboard.
