Use the dialog boxes to set the following parameters for the AT-2500:

Speed/Duplex

Network Address

Early TX Threshold


Speed/Duplex
Speed/Duplex:

The Speed/Duplex parameter can be controlled by either the adapter-card hardware settings or by the driver parameters. This parameter allows the driver to override the hardware setting. The hardware setting is accessible through the SETUP25 utility found on the CardAssistant disk.

Hardware: 	Adapter card hardware setting in effect

Auto-Sense:	Enable 802.3u auto-negotiation

10Mb/Half Duplex:	Force port to 10 megabits per second, half duplex

10Mb/Full Duplex:	Force port to 10 megabits per second, full duplex

100Mb/Half Duplex:	Force port to 100 megabits per second, half duplex

100Mb/Full Duplex:	Force port to 100 megabits per second, full duplex

Network Address
Network Address:

Also known as the LAA (Locally Administered Address), this property is used for applications where the pre-programmed media access control (MAC) address must be overridden. To preserve the original factory-set MAC address, click Skip. To enter an alternate MAC address, type a 12-digit hexadecimal number and click OK. To revert to the original MAC address, enter twelve zeros in this field and click OK.

Early Tx Threshold
Early Tx Threshold:

The AT-2500 is capable of starting to transmit a packet before it is completely transferred from memory to the network adapter’s buffer. This number determines how much data is transferred before the packet transmission begins. Adjust this parameter upward to reduce fragments observed or downward to optimize throughput. The default range is 9 to14.
