Page 7: Chapter 1 Cpu-1220 Ethernet Interface
Chapter 1 CPU-1220 Ethernet interface The CPU-1220 Ethernet interface features a single-chip Fast Ethernet controller Realtek RTL8139 that provides 32-bit performance, 10/100Mbps auto-sensing, and full compliance with IEEE 802.3u 100Base-T specifications and IEEE 802.3x Full Duplex Flow Control. The versions of the Relatek RTL8139 chipset installable over the CPU-1220 board are: RTL8139 B RTL8139 C Between the two devices there are only different electrical characteristics. -

Application Note Ground signal LED2 On receiving packets Ground signal 100/10Base-T transmit data 100/10Base-T transmit data J9: Status LEDs The HDD and Ethernet activity LEDs are implemented on the J9 connector. It is a 3x2 pin - 2mm step. The following table shows the J9 connector pinout: Table 3. - Page 10 Application Note Important Note. Connection to a 100BASE-TX hub for 100 Mbps operation requires Cat. 5 Unshielded Twisted-Pair (UTP) cable or Cat. 5 Shielded Twisted-Pair (STP) cable. The maximum length between the 100BASE-TX hub and the adapter is 100 meters. Connection to a 10BASE-T hub for 10 Mbps operation requires a Cat.
- Page 11 Application Note Generic Ethernet adapter Eurotech has developed a fail-safe circuitry that can be installed to prevent faulty and damages. To prevent wrong connections between the CPU-1220 and the Ethernet adapter Eurotech has developed a generic adapter that can be used together with the CPU-1220 for installing both the Realtek chips. The following drawing describes the solution for a generic Ethernet adapter tolerant regarding the supply voltage present on pin 1 of J4 CPU-1220 Ethernet connector and based on the version of the Realtek RTL8139 chipset installed, and that may be integrated into a carrier board.
