ethernet card
Hi I puchased a socket LP-E pcmcia card from an auction site. Unfortunately the socket pcmcia card was supplied with a xircom connectivity cable and it doesn't work. Is it possible to rewire an existing connectivity cable ? I have attempted to use an oscilloscope on an RJ45 cable to see if I can compare the trace on the 'unknown' cable with a 'known good pcmcia card with cable' on the oscilloscope when using the 'ping' command,(but the cable is going nowhere, unterminated) and I find that I cannot get a good result. Can I use an oscilloscope to view the result of a ping command ? What results should I expect on the 8 pins of a RJ45 cable ? thanx GC |
