Step 1: we must first connect the power of each hardware device. Second, insert the telephone LINE into the LINE port of the modem, and use an Ethernet cable (non-crossover) to connect the Ethernet port of the modem to the WAN port of the router. Then, use an ethernet cable (non-crossover) to connect the LAN port of the router (either of the interfaces provided) t

After removing the gray plastic protective layer, you can see the 4-to 8-core wires of the twisted pair cable, and the colors of each pair are different. Each pair of core wires is composed of a colored core wire and a white core wire with only a few colors. The four full-color cores are brown, orange, green, and blue. Each pair of wires is intertwined. When creating a network cable, you must unbind, straighten out, and straighten the eight wires of the four pairs one by one, then,
DMA capabilities. The UART port supports 5 to 8 data bits, 1 or 2 Stop bits, non-validation, odd verification, and even verification bits. The following describes how to use UART in terms of hardware and software.
First of all is the hardware circuit connection, the serial circuit of the ADSP-BF533 is basically the same with the single chip microcomputer, 1 shows, in the BF533 Chip Pin, there are two dedicated Serial Port IO Tx and Rx, then, in Figure 2, the two pins are converted to the comput

When an external connection is used, it returns to the query result set that contains not only rows that meet the connection conditions, but also the left table (when the left outer connection is used) and the right table (when the right outer connection is used) or all data rows in two edge join tables (all Outer Join. For example, use the left outer link to connect the Forum content to the author information:

Production and Application of direct connection network cable and Cross network cable production and application of direct connection network cable and Cross network cable (cross line) one is the standard of the T-586A, the other is the standard of the T-568B can be directly connected to two computers (NIC-to-nic)
Ordinary network cable (straight line) two ends are generally T-568B Standard
So: You need a dedicated network cable, or you can change the remaining line (only change the header)

use the switch to send the packet to its output port. If a router is added to a queue at the input end, several inputs share the same switch. In this way, the last function of the input port is to participate in the arbitration agreement for public resources (such as the switch.
The switch can be implemented using different technologies. So far, the most widely used switch technology is bus, cross switch and shared storage. The simplest switch uses a bus to connect all input and output ports. T

Why? Readers who have used computers know that when CPU fans experience poor heat dissipation, computer systems often crash or automatically restart, especially for network devices, high-speed CPU and core components need to run in a suitable working environment), too high temperature will damage them.

Because no Screen Shield is provided, the cables are relatively soft, but their connection methods are the same. In general, there are four pairs of lines twisted together in the cat5e category and marked with different colors.
Twisted Pair wires have two Connection Methods: EIA/TIA 568B standard and EIA/TIA 568A standard.

The connection string is also divided into two parts: pass-through and cross. The connection is generally used to prolong the connection between the PC and the device. 2, 3, and 5 are connected to 2, 3, and 5 respectively, because the PC is generally a public head, most of the devices are headers, so they are common and can be used for extension or connection. Crossover is generally used for connection between PCs, set 2 to 3, 3 to 2, 5 to 5. Generall
