misoperation caused by accidental factors such as Jitter and raindrops. Generally, the test mode is used for debugging. After normal operation, select the working mode. You can select the desired mode based on the mode on the right.
10. Save: any operation is performed on the panel. If you need to keep this setting after power-off, press the save key to save it. This setting is still the case when you start the system next time.
Alarm experiment and damage prevention experiment
1. Close alarm:
downward wheel place to reduce the sag, reduces the tension. Then in the pulley between the traction rope, traction rope tied to the cable's traction head, with a certain traction to allow the cable to climb up the pole, hanging on the puppet. The spacing between cable hooks is 40cm, hook on the puppet of the buckle direction to be consistent, each of the poles must have a convex drip ditch, each cable in the joints should be left with the bar length plus 3m allowance, in order to continue the

For a long time, people have been using copper wires to transmit sound and information. However, more and more fiber cables have been used recently. Due to cost problems, we cannot replace all copper wires with optical fiber cables at once. However, to convert some cables into optical signals, the most important thing is
Nano-optical cables that can replace computer copper wires will be available
Following the invention of the optical fiber technology that revolutionizes data transmission speed and capacity, the University of Alberta's electronic engineers broke another obstacle and recently successfully designed nano-optical cables that can replace copper wires in computer chips, it can significantly increase the comput
Electrostatic inductionPerimeter detectors are very sensitive sensors. To ensure proper use of the system and give full play to its functions, the project installer must carefully read the product instructions before construction, check the cables, ground wires, power cables, and installation according to the product instructions carefully before determining the fault. Then, the test starts after 5 minutes

Step 5: carefully strip each pair of cables, because we follow the EIA/TIA 568b standard to create connectors, so the lines have a certain order of color ().
Note that the Green Line should span the blue line. The easiest thing to make mistakes here is to put the white green line and the green line together, which will cause crosstalk and reduce transmission efficiency. From the left: White
adaptive NICs, the speed of the network adapter depends on the bandwidth of the network device connecting the other end. If the other end is connected to a m network device, the network connection will be switched to a m physical connection rate.
It is worth mentioning that at present, Most laptop built-in NICs Support automatic adaptation of RJ45 568a and 568b in Two-line sequence, which makes it very convenient to create and find Ethernet connection cabl

2403F, and connect to the Internet with a PC under 2403F. It is found that the Internet is normal and there is no disconnection. Packet Capture on the PC also shows that many target MAC servers use unicast ARP packets. At this time, check the Debug DHCP debugging information on 5200 and find that all DHCP detection reports of ARP have responses from online users.
5. It is suspected that S3025 will discard this target MAC as the unicast ARP packet, but this is in conflict with the user's ability

Unshielded twisted pair UTP) copper cable can be used for different purposes, in general, it contains an eight-pin RJ45 interface.
A normal Ethernet copper network cable can be used to transmit electrical signals from one end to the other. A direct connection network is used to c

Super 6, commonly known as 6A, is a 10 Gigabit system. For testing, it is necessary to achieve a MHz test, divided into unshielded and shielded systems. For a non-shielded system, a 6 packet 1 External crosstalk test is required. Currently, FLUKE and ajelun both have this test instrument. The unshielded structure is currently popular on the basis of the six categories. The Twist distance is more dense and the wire diameter is thicker. The most important change is the change on the PVC outside, a

is still made of Wired materials such as network cables. The most important reason is the bandwidth. If a wireless network is used, it is difficult to control the number of clients in the same cell. There may be only one client in the cell, or hundreds of clients in the cell. Although the number of wireless clients can be properly controlled by adjusting the cellular size. However, the intensity of its control is far less powerful than that of wired
Generally, the Integrated Wiring System is updated every seven years. It takes five years to replace the three-category system with the Five-category system. It takes only three years, cat6 systems are mature and increasingly widely used. It is a trend to implement Gigabit Ethernet in cat6 systems, and standards for cat6 systems are being formulated and initially implemented, bringing copper cabling systems to the fullest is the latest goal of 10 Gigabit copper

Whose lines are not messy? As long as you have mastered the wiring rules, you can understand the line.
What is the wiring rule?
Generally, construction from the end of the line to the end of the line is recommended. Specifically, wiring starts from the lamps or sockets at the last end, so that each wire along the line is collected to the distribution box and di
