3.1
Power supply connection
The operating main supply voltage is in the range of 20-48 V.
Figure 18.
Main supply connection (highlighted in yellow)
The input DC voltage has to be connected to J9 connector. When the board is powered, the 15 V, 3.3 V and 5 V
voltages are generated and the green LED (close to NETX90, D11) switches on.
3.2
Ethernet real-time connectivity
Connectivity is managed by the NETX90 network controller. Once the
evaluation board is
powered, add it to the network through an EtherCAT master (implemented with a software tool or hardware) and
an Ethernet cable using RJ45 connector as shown in the figure below.

The green LED close to RJ45 connector starts blinking when a scan procedure through the master EtherCAT is
performed. The LED remains always ON if the communication has been properly established.
