These switch settings typically work with any
Ethernet Version 2.0 or IEEE 802.3 controller
device. You may change the Half Step switch
and Collision Mode switch to optimize opera-
tional parameters for a particular controller type.

To make these optimizations, you must know
the following two facts about your Ethernet con-

1.
Is the controller Ethernet V2.0 or IEEE
802.3?
802.3?
Most new products today are based on the
IEEE 802.3 AUI interface standard. Some
controllers are still based on Ethernet V2.0.
Differences exist between the two standards
in AUI pinouts and signaling characteristics.
If you are in doubt, keep the Half Step
switch enabled.
