Gee – such an open ended question. A – which version of IEEE 802 are you trying to implement? B – What format of media are you using, Coax, UTP, proprietary? C – If we cut to the chase and presume 802.3 and TCP/IP and UTP (RJ45) connetions and 10MB half or full, then you need a crossover cable from device to PC. [No MAC then you cannot use a hub or switch!] At that point ‘Google’ Ethereal and WinCap to setup a workstation that can capture packets and display them on the PC [if using Linux instead of Windows you won’t need WinCap].
Without a MAC address then DHCP and DNS won’t work and forget going through switches or routers.
