Abstract

A cable is capable of communicating signals between a monitor and a physiological sensor. The monitor is capable of activating individual light emitters of an emitter array arranged in an electrical grid by driving at least one of row drive lines and at least one of column drive lines of the electrical grid. The cable has a first row input, a first column input, a second row input and a second column input. The cable also has a first output which combines the first row input and the first column input and a second output which combines the second row input and the second column input. The inputs are adapted to connect to electrical grid drive lines of a monitor. Further, the outputs are adapted to connect to contacts of a physiological sensor having back-to-back configured LEDs in electrical communication with the contacts.
