RSE Power
The rear seat entertainment (RSE) uses a switched battery voltage feed circuit for power moding. The radio outputs power to this circuit via the entertainment remote enable signal circuit.
RSE Grounds
The vehicle harness provides a ground for the RSE circuits.
RSE Data Link Communication
The RSE does not communicate with serial data.
RSE Outputs
At minimum volume, the plus (+) and minus (-) audio signals are approximately half battery voltage, measured to vehicle ground. These audio signals are sent from the radio to the Infrared Module, most systems have a common minus (-) signal.
