A.2 Auto-negotiation Function
The adapter is equipped with an auto-negotiation function. Auto- negotiation is a negotiation procedure between two connected de- vices. Both devices must be auto-negotiation capable. The proce- dure decides the best operation modes that can be used for the data transfer operation between two connected devices. The operation modes includes 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 200 Mbps depending on the connection speed 100 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 (such as a hub) 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.
