Monitor LEDs - LEDs are on the PCM-NE2000 to pro- vide a visual status of the module. The green Transmit and Receive LEDs light when the module is transmitting data to or receiving data from the network. The yellow Link Integrity LED lights when there is a valid connec- tion to a 10Base-T concentrator and the yellow Board Select LED lights when the module is selected. The red LED lights when a collision is detected. Software - The board emulates one of the most popu- lar Ethernet Adapter architectures – Novell's NE2000 adapter. This means that most PC-compatible drivers, utilities and Ethernet supported operating systems will work directly with this module.
