Abstract
Abstract Disclosed is a physiological electrical signal connector system which one connector connected to an electrode set and another connector connected to a digital signal convertor which leads to a patient monitor. Each type of electrode set has a specific code identified with it and when connected to the digital signal convertor, the connector code is recognized by the digital signal convertor. The connector code is then relayed to the monitor which will self-configure based on the identified code.
