Application for Ethernet Switch Industry, 4-port:

Connect Ethernet devices in the control cabinet

and if needed also power them at the same time


Operation using external power

  • Standard Industry Switch for 24V power

Mirror port

  • Mirror network traffic

    (Click on image to enlarge)

    DIL switches 1 - 3 are used to select which port should operate as the mirror port (It is not possible to operate multiple ports as the mirror port). The entire network traffic passing through the switch is output on the mirror port. Since the mirror port has a read-only function, the PC connected to this port cannot access the network for normal operation.
