KTI Networks KF230TX, KF223TX Auto-negotiation Function, Duplex mode half-duplex or full-duplex

A.3 Auto-negotiation Function

The adapter is equipped with an auto-negotiation function. Auto-ne- gotiation is a negotiation procedure between two connected devices. Both devices must be auto-negotiation capable. The procedure de- cides the best operation modes that can be used for the data transfer operation between two connected devices. The operation modes in- cludes connection speeds and duplex modes as follows:

Connection speed : 10Mbps or 100Mbps

Duplex mode : half-duplex or full-duplex

Operating at full duplex can increase the network bandwidth to up to 20 Mbps or depending on the connection speed 200 Mbps.

The following table describes how the adapter decides the operation modes when it connects to :

An auto-negotiation device

Speed: via auto-negotiation

Duplex: via auto-negotiation

A non-auto-negotiation device

Speed: auto-sense the connection speed

Duplex: half-duplex as default (*)

*The default could be overwritten by configuration setting or keyword setting of each individual network driver when the driver is loaded.
