MediaGateway
User Manual
15
The power supply for the device is supplied by Pin 1 (12Volt) and Pin 2 (Ground).
Requirements for the MediaGateway itself: 12 Volts DC up to 1 Ampere (typical
600mA)
Please note, that the power supply for the 12 Volts camera power output is also
supplied form Pins 1 and 2.
Warning:
If you apply a voltage higher than 16 Volts, the device will be damaged!
A wake-up line can be connected on Pins 7 or 8. The wake-up line should have the
same voltage level as the power supply (12 Volts). A high level on one of these pins
wakes up the ECU from sleep mode and keeps it active. If the voltage on this pin drops
below approx. 6 Volts for more than about 3 seconds, the ECU will enter sleep mode
until voltage increases and it wakes again.
The LIN interface on Pin 9 can be used to communicate with the microcontroller by
LIN bus. In the default software there is no data transmission specified. This interface
may only be used in customer specific software.
The FlexRay interface on Pins 17 and 18 can be used to communicate with the
microcontroller by the FlexRay bus. In the default software there is no data
transmission specified. This interface may only be used in customer specific software.

The pins marked with (P) or (N) are used for the 100BASE-T1 ports. Four ports are
available per switch.
