Description

RSE System
The RSE system contains the following components: DVD player, Roof Mount 8-inch WVGA LCD monitor with IR transceiver, IR remote controller, and IR headphone. The RSE system is designed to be functional with Audio H/U. The entire system is awake and operational whenever the vehicle is in either Ignition or Accessory power modes. The RSE system communicates with one of the Head Unites via CAN Serial Data Bus, The main control circuit of the RSE system resides in the DVD player module which communicates with the Roof Mount Display Module.
In the Audio Head Unit system, the H/U audio signal can be passed to RSE system. The RSE has the ability to pass certain pre-defined controls to the Head Unit via remote controller through CAN bus.
For Radio H/U, only the RSE system can be sent its audio signal to this head unit. Head unit doesn't send audio signal to RSE system. RSE and H/U system can be controlled by each other via CAN Serial Date Bus.
The entire RSE system including the LCD monitor Display and DVD mechanism is controlled by a ON/OFF switch located at the Roof Mount Display Module. While in its ON state, the RSE system is set up to accept the commands from functional buttons located on the Roof Mount Display Module or from the IR Remote Controller. There is a position-sensing switch located inside LCD Module to turn ON or OFF the LCD monitor power when its position is at 25 +/- 10 degrees from the closed and latched position. The RSE system has IR emitters to transmit a single channel stereo audio signal of the playing state to a matched IR wireless headphone.





LCD Monitor Protective Operation
The monitor display has a built-in thermal sensor to sense the inside temperature of the monitor display package. This senor output is fed to a processor which will activate protective measure when the monitor operating temperature is rising close to the maximum allowable operating temperature limit of +76 ± 5°C.

DVD Mechanism Performance
The DVD player is a single player.
The player is only capable of reading the bottom side of a disc. When inserting single sided disc the label should be up.

Wireless Headphone
When the RSE is ON, its audio signal is transmitted from the IR transmitter located in the LCD monitor and is received and played back through the IR Headphones. The wireless headphone volume can be adjusted via the rotary volume on the headphones. The IR headphone is a single channel design.
