Recommended cable selection for LAN Monitoring System Integrated Wiring In the LAN, the monitoring system is widely used, including transmission lines, hubs, network management centers, and other devices. The information network is based on the Integrated Wiring System, it directly affects the performance of the security monitoring system. In this regard, it is directly related to the media used to transmit image signals, including coaxial cables, tw

Step one: When the computer is turned off, connect the purchased data cable to the same port or serial port on both computers. The port types used on both computers must be the same. In addition, the COM2 of serial port is superior to COM1, should use COM2 as far as possible. Step two: Start the computer. Install "NetBEUI" and "ipx/spx" communication protocols on both computers. On the desktop, click "Start", "Set" one "Control Panel", double-click N

A cable with a jack is found in the chassis, and the surface of the slot is marked with some English letters. This is the motherboard control line. In the lower right corner of the motherboard can be found in a row of pins, the needle is also printed next to some English instructions, this is the place to plug the control line. First step: Connect the Power switch control line. The power switch control line is indicated in English as either "powered

Printers are an indispensable office equipment for every company, and some families also buy printers, but how do they connect when they buy a printer? The printer interface also refers to the type of interface that is used between the printer and the computer, and the main interface types of the printer products currently on the market include common parallel interfaces, Professional serial port as well as the mainstream USB interface and is not a very common network port. Win7 flagship system

The answer is yes, through the USB data cable to achieve! Below we introduce the computer through the USB Data Cable Connection tl-tr761 series sharing Internet usage method. When a computer is connected to a device through a USB cable, if the computer is a windows 7 and Windows 8 operating system, You do not need to manually install the driver, the system c

The crossover network cable is used for the connection between the adsl modem and the HUB (not all of which are related to the MODEM design). The connection between the HUB and the HUB does not pass the cascade connection port, and the two computers are directly connected to each other through the NIC. The production method is basically the same as the above, but the online order is not like 568B. It adopts the 1-3, 2-6 exchange method, that is, one u

In general, if the network port of the host is connected to the network cable and can access the Internet, the default installation of the VM is as follows, in VM-Settings-Hardware-Network Adapter-Network connection, select the Bridged connection mode and disable the firewall under the window. Therefore, windows and VM can be pinged easily, however, when the network port of the host is not connected to the network, it is not so easy to ping each other

Generally, the theoretical distance of Category 5 network cables cannot exceed 100 meters. If the network cable is too long or light, the signal is unstable, and the Internet access speed is slow. If the network cable is heavy, there is no signal. To address this problem, I have summarized several solutions:I. Using six types of network cables, although similar to the transmission distance of over five type

Symptom descriptionA certain Bureau adopts the MA5200 + 2403F networking mode. Due to the small amount of upstream optical resources, the 2403F cascade mode is adopted in the residential area, and the cascade mode adopts five category of twisted pair wires, you can use PPPOE to access the Internet. Some second-level switch users report that the Internet access speed is slow.Alarm informationThere are many CRC verification errors on the upstream port of 2403F.Cause AnalysisDue to network

In many cases, after the computer is connected to the LAN interface of the D-LINK router through the network cable, the local connection will show unable to connect, the specific solution is as follows:1. Set the NIC speed to 10 MB. Click Control Panel → network connection → local connection → right-click Properties. In the Properties dialog box for local connection, click Configuration → advanced, force the NIC speed to 10 MB full duplex.2. If the ph
