The WinSystems PCM-NE2000-16 is a PC/104-based Ethernet controller module for embedded and industrial systems requiring cost-effective network connectivity. Built around the National DP83905 (AT/LANTIC™) controller, this 16-bit interface card implements IEEE 802.3 standard 10 Mbps CSMA/CD networking. NE2000 architecture compatibility ensures broad driver and OS support across real-time and commercial operating systems. The module supports three network media options: 10Base-T via onboard RJ45 transceiver, 10Base5 through integrated AUI interface, and 10Base2 via external BNC variants. Configuration options include software-selectable settings stored in onboard EEPROM or manual jumper setup. A memory socket accommodates 27C256 EPROM devices for auto-boot applications. Five status LEDs provide real-time network activity indication.
