INPUT/OUTPUT APPARATUS AND METHODS FOR MONITORING AND/OR CONTROLLING DYNAMIC ENVIRONMENTS

Apparatus and methods for flexible input/output signaling over a same signaling channel are described. A programmable interface circuit includes a signaling channel that can be adapted, prior to use or during operation, for transmission and/or reception of different types of analog and digital signals. The interface circuit can be used for communications between an isolating communication controller and components of a machine that use diverse signaling types.
