An interface assembly, system and method for inputting information from a source to a data processor, for example, a computer, which includes a means for translating electrical information into a non-electrical signal and retranslating the non-electrical signal back to an electrical signal to eliminate noise. The interface system also has a capability of being readily checked to facilitate locating troubles in the system.
A solid state control and display board wherein a total configuration of connected elements is shown together with switchable connections with semiconductor light emitting elements used to generate switching command signals, display opened and closed circuits and provide output signals.
