ADAM-4572 Modbus Serial Device

2.2.3 Ethernet Port Wiring
The ADAM-4572 uses a RJ-45 connector to interface with the Ethernet,
and supports 10/100 Mbps transmission speed. The ADAM-4572 con-
figuration utility will auto-detect the current transmission speed on the
network and configure itself accordingly. Furthermore, we provide 1500
Vrms isolation for the Ethernet end to protect the ADAM-4572 from
damages caused by over-voltage.

Grounding
The ADAM-4572 Ethernet interface, as required by the Ethernet stan-
dard, must be grounded.
