It is based upon the Intel 82551QM controller that is are accessed by the host CPU to read or write information supported by a wide range of operating systems including to the on-chip registers. The CPU also provides the Windows 98, Windows NT, Windows CE, QNX, 82551QM with the necessary commands and pointers that VxWorks, and Linux. allow it to process receive and transmit data. FUNCTIONAL CAPABILITY Full Duplex - The 82551QM can operate either in half duplex or full duplex mode. When operating the full PC/104-Plus Interface - The PPM-10/100-G module is duplex mode, it can transmit and receive frames simultane- designed to offer flexible, high-performance Ethernet ously. The selection of duplex operation and flow control networking capability. It provides 32-bits of addressing is done in two levels: MAC and PHY. The PHY duplex and data, as well as the complete control interface to mode is set either by Auto-Negotiation or, if Auto- operate on the PC/104-Plus Bus. The chip has a PCI Negotiation is disabled, by setting the full duplex bit in bus master interface and is compliant with the PCI Bus a register. The MAC duplex selection is done only through Specification. CSMA configuration. The CSMA configuration should match the result of the Auto Negotiation. Multiple PPM-10/100-G boards can be installed and supported on a single PC/104-Plus stack. There is a jumper Flow Control - The controller supports IEEE 802.3 frame block on board to select the module slot position. based flow control frames only in both full duplex and half duplex switched environments. Flow control is optional in There is also a PC/104 connector on the board. No power, full-duplex mode and can be selected through software control or data signals are wired to it. It simply feeds the configuration. There are three modes of flow control that signals through the connector to the next module in a stack. can be selected: frame-based transmit flow control, frame- based receive control and none. Ethernet Controller - The PPM-10/100-G module uses the Intel 82551QM integrated controller. It consists of both 100BASE-T - The PPM-10/100-G will auto detect and the Media Access Controller (MAC) and the physical layer configure to the speed of the link partner. The PHY unit (PHY) on a single chip. supports 10BASE-T half duplex, 10BASE-T full duplex, 100BASE-T half duplex, and 100BASE-T full duplex. The 82551QM acts as both a master and a slave on the PCI bus. As a master, the 82551QM interacts with the system Since 10BASE-T and 100BASE-T have different filtration main memory to access data for transmission or deposit needs, both filters are implemented inside the 82551QM received data. As a slave, some 82551QM control structures chip. This allows the two technologies to share the same magnetics. detected. If the link fails while in Auto-Negotiation, the LED will keep the last valid link state. If 100BASE-T link is forced, the LED will be on, regardless of the link status. Software - The board emulates the popular Intel Pro100+ PCI board. Intel has driver support for the most popular operating systems and real time operating systems for its 82551QM controller. Therefore most PCI-compatible drivers, utilities and 10/100 Ethernet supported operating systems will work directly with this module. INTEL 10/100 ETHERNET RoHS Compliant - This product is designed to meet the CONTROLLER Directive on the Restriction of the use of certain Hazardous Substances in electrical and electronic equipment (RoHS) European Union directive 2002/95/EC.
