AutoDetect
Check once the 10BaseT (TP), 10Base2 (BNC) and 10Base5 (AUI) media ports and select the first live media.

This detection takes place during driver initialization: the wire should be connected before the system boots and media  cannot be switched during run time.

AutoDectect does not check 10BaseT's Full_Duplex and No_Link_Test modes.


AutoSense
Autosense the media ports supported by the Adapter and dynamically switch to the live media.

(AutoSense does not sense 10BaseT's No_Link_Test mode.)


AutoSense - No_Nway
Autosense the media ports supported by the Adapter and dynamically switch to the live media.

Nway's negociation is disabled.

(AutoSense no_Nway does not sense 10BaseT's No_Link_Test mode.)


10BaseT
Select the 10BaseT medium connection (RJ connector).


10BaseT - Full_Duplex
Select the 10BaseT Full_Duplex medium connection (RJ connector).


10BaseT No_Link_Test
Select the 10BaseT medium connection (RJ connector) with no Link Integrity Test.

Choose this option if the Adapter is connected to a hub which does not generate link pulses to check the link integrity.


10Base2 - BNC
Select the 10Base2 medium connection (BNC connector).


10Base5 - AUI
Select the 10Base5 medium connection (AUI 15_pin connector).


100BaseTx
