EtherLan User GuideImportant: Ethernet Port Auto-configuration 3When your i3 EtherLan `combo' card is initialised (when the computer is switched on, oris hard reset by pressing Ctrl-Break) it first checks its l OBaseT (twisted pair) socket. If itdoes not find a 'good' connection to that socket it assumes that the l 0Base2 connector isthe one which is in use. If your i3 EtherLan card is to be used with a 10BaseT connectionit is essential that the connecting lead is plugged in at the hub and at the computer, and thatthe hub is switched on, before you turn on the computer.An Ethernet hub sends regular 'good link' pulses on its Tx (transmit) connection. Whenyour EtherLan combo card is initialising it checks whether these pulses are arriving at its10BaseT Rx (receive) connection. If they are then it configures itself to use its 10BaseTport; if not, it assumes the 10Base2 port is the one which will be used.If you want to connect a computer to a 10BaseT Ethernet and have switched the computeron without a 'good' connection to its l 0BaseT socket you will have to make the correctconnection and then perform a Ctrl-Break on the computer (or turn it off , wait a fewseconds and then turn it on again) before it will recognise the I 0BaseT connection.TestingHaving configured the computer, the net icon will appear at the left of the icon bar. Thisindicates that the computer has recognised the i 3 EtherLan card and loaded and initialisedthe AUN software.1. Press F12 to get to the command line and enter:*ehinfo(for a full description of this command see page 10). This will print out informationabout the state of the network controller, including whether the software is having toauto-correct a reversed l OBaseT connection.2. Check that the network interface type has been correctly identified.3. No error messages should be given unless the card is not connected to the network, orthe network cable is not correctly terminated.4. If you have another AUN-configured station connected to the network a final test canbe performed using the Netprobe command (see page 13). If you use the Netprobecommand with the net number and station number of a working station the Stationpresent response should be given. If the response is Station not present then checkthe network cabling and the configuration of both computers.Self Test and Cable CheckOn power on or after a hard reset the software on the i3 EtherLan card performs a self testand cable check. The self test checks the on board buffer memory, controller chip andnetwork interface. The cable check determines whether there is a cable attached to the cardand, if there is, whether or not it is terminated. If the card is connected to a l 0BaseT3 Not applicable to EtherLan 200 series cards. In addition, EtherLan 100 and 500 series combo cards are fittedwith a link which can be used to force the card to use the 10Base2 or the 10BaseT socket -see the InstallationInstructions If the link is left off the card will auto-select which socket to use, as described in this section.-7-ELANUG:214, Issue 2.1 |
