 （即，没有两个节点应该具有相同的节点ID）。节点ID的顺序并不重要。通过主机系统向板载SDRAM的写入来启动网络上的数据传输。写入可以像PIO目标写入一样简单，也可以是由于驻留DMA引擎的DMA循环。当写入SDRAM时，RFM‐5565上的电路会自动将数据和其他相关信息写入传输FIFO。从传输FIFO，传输电路检索数据并将其放入4至64字节的可变长度数据包中，该数据包通过光纤接口传输至下一块板的接收器。然后，接收器检查数据包是否存在错误。当接收到无错误数据时，接收电路打开数据包并将数据存储在电路板的接收FIFO中。从接收FIFO，另一个电路将数据写入本地板载SDRAM中与始发节点相同的存储器相对位置。该电路还同时将数据路由到电路板自己的传输FIFO。从那里，重复该过程，直到数据返回始发节点的接收器。在始发节点，数据分组被从网络中移除。2.2前挡板LED指示灯RFM‐5565在挡板上有三个LED指示灯。顶部的红色LED是一个状态指示器；状态LED可以通过写入LCSR1寄存器的位31而切换为OFF或ON，(i.e. no two nodes should have the same node ID). The order of the node IDs is unimportant. A transfer of data over the network is initiated by a write to onboard SDRAM from the host system. The write can be as simple as a PIO target write, or it can be due to a DMA cycle by the resident DMA engine. While the write to the SDRAM is occurring, circuitry on the RFM‐5565 automatically writes the data and other pertinent information into the transmit FIFO. From the transmit FIFO, the transmit circuit retrieves the data and puts it into a variable length packet of 4 to 64 bytes that is transmitted over the fiber‐optic interface to the receiver of the next board. The receiver then checks the packet for errors. When the error free data is received, the receive circuit opens the packet and stores the data in the board’s receive FIFO. From the receive FIFO, another circuit writes the data into the local onboard SDRAM at the same relative location in memory as the originating node. This circuit also simultaneously routes the data into the board’s own transmit FIFO. From there, the process is repeated until the data returns to the receiver of the originating node. At the originating node, the data packet is removed from the network. 2.2 Front Bezel LED Indicators The RFM‐5565 has three LED indicators located on the bezel. The top red LED is a status indicator; its power up default state is ON. The status LED may be toggled OFF or ON by writing to Bit 31 of the LCSR1 register,
