Getting Started with Adapt11ET24FX Ethernet Card
What you need:
  • a computer running WIN98/NT
  • a network card in your computer
  • Sniffer by Ufasoft
  • the rest of the stuff to connect your computer to the Ethernet of the board (e.g. 1 crossover cable, or a hub + 2 standard ethernet cables)
  • make sure your board has a properly executed hardware patch (some early Rev. 0 boards had mistakes)

    •

    Sniffer is a shareware prgram that lets you trace packets being sent over your network. It is very easy to use.  You need to know 2 things:

    1. the IP address (e.g. 192.96.0.1) of the computer/unit you are sending the packet to
    2. the port you are using to send and receive the packet (e.g. 223)
    You can then use Sniffer to pick up all the information being sent to the other unit/computer. If you're using 2 units, and have a hub, you can monitor the traffic going back and forth between both units-- you just need to monitor two IP's instead of one.

    Be aware that after 14 days you will need to purchase the Sniffer software if you want to continue using it.
