Block diagram
To meet the requirements for operation in the vehicle, the connections of the
ES600.2 are each routed to a Lemo socket.
5.2
Power supply
The power supply connection "7-29 V DC" is routed to a 2-pin plug connector
(Lemo socket) to the rear side of the module. An external power supply or the
vehicle battery supply the module with current.
When connecting the ES600.2 with operating voltage and an active Ethernet
connection to HOST, the module boots. If the Ethernet connection does not
exist, the module changes to the "Standby" operating state.
NOTE
The ES600.2 must physically be isolated from all supply voltages so that the
module does not consume any current.
