Power Supply (6-32V DC)
The power supply interface (6-32V DC) is routed to a 3-pin connector (XLR
socket) on the front of the device. An external power supply or the vehicle
battery power the module.
When the ES511.1 is connected to the operating voltage and there is an Eth-
ernet connection at HOST, the module boots. If there is no Ethernet connec-
tion, the module changes to “Standby.”
3.3
Ethernet Switch
The integrated Ethernet switch is used for the connection of the ES511.1 mod-
ule and other measurement or interface modules to a user PC. Data from the
connected modules of the ES51x line is acquired synchronously (ETAS device
