CompactPCI  10/100Mbps Fast Ethernet Hostadapter

The CompactPCI ® bus emerged as the popular standard for modular, industrial computer systems. The hostadapter CN1-CONGA from EKF interfaces any CompactPCI ® systems to the most popular networking class, the 10/100Mbit/s Ethernet/Fast-Ethernet LAN.

The 3U board (single sized Eurocard) is provided with a Twisted Pair interface according to IEEE802.3 (ANSI 8802-3) 10Base-T and 100Base-TX, half- and full-duplex. By employing the Auto-Negotiation algorithm, the technology capabilities of the remote link partner may be determined and operation automatically adjusted to the highest performance common operating mode.

The CN1-CONGA is built around the high-end LAN controller chip DEC 21143. Equipped with smart functionality and hardware features as FIFOs and several DMA channels, the 21143 minimizes the hosts load. All popular operating systems, for example Windows98/NT or Linux, come with ready to use 21143 networking drivers. As an frontend, the ICS 1890 PHY (physical layer adapter) chip cares for a maximum data rate of 200Mbit/s in full-duplex, Fast-Ethernet mode.

The CN1-CONGA should be connected to the LAN (typically hub or switch) by shielded twisted pair (STP) and unshielded twisted pair (UTP) CAT5 cables up to a maximum length of 105m.

As an option, the CN1-CONGA provides full support for an upgradeable Flash BIOS ROM up to 256KB. This feature allows for remote boot from any node in the the net.

A serial EEPROM is provided for storing the unique Ethernet address, and the CN1-CONGA hard configuration and control data.

The status of the CN1-CONGA is indicated by an array of four LEDs. The jumperless board can be installed in a plug & play manner.

The CN1-CONGA performance will be explored best with a self-learning Fast-Ethernet switch as the remote link.
