Ethernet interfaceEdit

RIALTO SBC has two Ethernet interfaces:

  • eth0 on J16 (labelled as Ethernet 1)
  • eth1 on J59 (labelled as Ethernet 2)

DescriptionEdit

The Ethernet interfaces are available at the connectors J16 and J59. Primary interface is on J16.

J16 and J59 are a RJ45 shielded connectors with link/activity led.

 
Ethernet 1 - J16 connector
 
Ethernet 2 - J59 connector
