Connection speed and duplex ************************************************************ ** ** ** Speed and Duplex Options for the ** ** for the AT-2450/2700 Series Adapter ** ** ** ************************************************************ Definitions ============================================================ ------------------------------------------------------------ Half duplex: The adapter can only transmit or only receive packets at any given time. It cannot transmit and receive at the same time. This is how traditional Ethernet works. ------------------------------------------------------------ Full duplex: The adapter can send and receive packets simultaneously. This feature can improve adapter performance by eliminating collisions. ------------------------------------------------------------ WARNING: The card and the connected device must be set to the same duplex mode. Incorrectly forcing a specific duplex mode may result in poor performance and data loss. Consult your LAN administrator before forcing a duplex mode or if you don't know the capabilies of the attached device. ------------------------------------------------------------ Speed: The AT-2450/2700 Series Adapter link speed is dependent upon the network segment and the capabilites of the AT-2450/2700 Series Adapter. ------------------------------------------------------------ Auto Negotiation: Auto negotiation is supported TX network segments but not in FL or FX network segments. NWAY: Another term for auto negotiation. Trademark of National Semiconductor Corporation. NWAY is support in TX segements but not in FL or FX network segments. ------------------------------------------------------------ Manually configuring duplex and speed: If the link is full duplex, manually set up the connection type using the SETUP utility on the CardAssistant diskette. ------------------------------------------------------------ Note: Performance may suffer if the link partner is not full duplex and you configure the adapter to full duplex. Leave the adapter on half duplex if you are not sure. ------------------------------------------------------------ Using SETUP to change settings: 1. Boot the computer into DOS with no drivers loaded. (In Windows 95, boot into the "Command prompt only" option. Press the F8 key when the message "Starting Windows 95" appears, and select "Command Prompt only", which is Startup menu choice 6.) 2. Insert the CardAssistant diskette in the floppy drive and launch SETUP; type "A:\setup". 3. Use the arrow keys to select the card (if necessary). Press ENTER. 4. Select Configuration. 5. Use Enter and the arrow keys to select connection. 6. Press F10 to preserve your change. * Third-party trademarks are the property of their respective owners.
