ORDERING INFORMATION

MCM-NE2000 STD Bus Ethernet LAN card

LPM-NE2000 CMOS STD Bus Ethernet LAN card

solely by the software thus providing a more user-

friendly Ethernet adapter. It is shipped from the facto-

ry with the EEPROM enabled and preprogrammed.

Monitor LEDs - LEDs are on the LPM/MCM-NE2000 to

provide 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 connection 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 detect-

ed.

Software - The board emulates one of the most popular

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.
