Ethernet interface

• Speed: The Ethernet speed the Digi device uses on the Ethernet network.

  • 10: The device operates at 10 megabits per second (Mbps) only.
  • 100: The device operates at 100 Mbps only.
  • auto: The device senses the Ethernet speed of the network and adjusts automatically.

  The default is auto. If one side of the Ethernet connection is using auto (negotiating), the other side can set the Ethernet speed to whatever value is desired. Or, if the other side is set for 100 Mbps, this side must use 100 Mbps.

• Duplex Mode: The mode the Digi device uses to communicate on the Ethernet network. Specify one of the following:

  • half: The device communicates in half-duplex mode.
  • full: The device communicates in full-duplex mode.
  • auto: The device senses the mode used on the network and adjusts automatically.

  The default is half. If one side of the Ethernet connection is using auto, the other side can set the duplex value to whatever is desired. If one side uses a fixed value (for example, half-duplex), the other side has to use the same.

• MDI: The connection mode for the Ethernet cable.

  Auto: Enables Auto-MDIX mode, where the required cable connection type (straight through or crossover) is automatically detected. The connection is configured appropriately without the need for crossover cables to interconnect switches or connecting PCs peer-to-peer. When it is enabled, you can use either type of cable and the interface automatically corrects any incorrect cabling. For this automatic detection to operate correctly, the “speed” and “duplex” options must both be set to “auto.”

  MDI: The connection is wired as a Media Dependent Interface (MDI), the standard wiring for end stations.

  MDIX: The connection is wired as a Media Dependent Interface with Crossover (MDIX), the standard wiring for hubs and switches.
