Abstract
A digital "signature plug" for applying digital signals representative of shaft characteristics to a digital shaft torque measuring system comprises a printed circuit mounted on an insulating support. The support has an input pin connected to a common printed circuit track, which is connected in turn to sixteen output pins via respective individual printed circuit tracks. The support is shaped beneath each of the sixteen individual tracks to facilitate severing of the track with a punch tool, so that any desired combination of the output pins can be disconnected from the input pin. Consequently, if a logic level 1 signal, for example, is applied to the input pin, any desired pair of eight-bit digital signals can be produced at the output pins.
