Supply PCI interface reflective memory card 03

Reflective Memory Network every reflective memory node (any 5565 reflective memory card) in the form of a daisy chain of interconnected using fiber optic cable. Transmitting the first card must be connected to the receiving end of the second card, the second card of the sending end is connected to the card receiving end of the third block, and so on until then is connected to the first card of the receiver is completed A complete ring connection. You can also connect all the nodes to one or more of the ACC-5595 Reflective Memory HUB, receive and send each node must be connected, if not detected optical signal or loss of synchronization reflective memory card RFM-5565 will not send packets (such as fiber optic cable has been damaged). Reflective memory network node number must be unique for each node, the node number by the DIP switch S2 board set, any two nodes can be set to have the same node number, node number for each card can be through NODEID When reading when generating a write operation of SDRAM, RFM-5565 reflective memory card automatically writes data and other relevant information to the transmission buffer (Other related information including the node number, the data address and other information), the transmit buffer vessel, the transmitting circuit detection data, and the data into a 4 to 64-byte packets of variable length. Send a card to receive a port through the optical fiber interface. Receiving circuit checks whether the packet error, no error occurs when data is received. Unlock the packet receiving circuit and stores the data to the onboard receive buffer. In the reception buffer, the other circuit to write data to the same address of the SDRAM and the local source node. Meanwhile, the circuit will simultaneously transmit the data to the transmit FIFO, this process is repeated until the data is returned to the source node of the receiving end, in the source node, the receiving circuit detects the same source node NODEID NODEID and packets, and therefore will packet is removed from the network, all of this node's data are updated.
