Abstract
An interface unit for establishing an electrical coupling of a number of sensor wires from a combination of catheters with a number of electrical signal channels of a electrophysiological monitoring system has a number of electrical contacts for coupling individual wires with individual channels. Each contact is releasably engageable with an individual wire. A number of overlays which are removably locatable at the outer surface and are attached to the housing of the unit by binding rings. Each overlay carries on a face thereof a visible indication of a different one of a number of stored wire/contact configurations. The configurations are organized such that contacts for receiving wires from a same catheter are grouped together and the indication is formed as visibly differentiated regions, each de-marking a different grouping.
