to the modem through a cable, it must be connected using a AYSNC-TO-DB25 or AYSNC-TO-DB9 adapter. There are more types of synchronous serial ports that can be supported in routers, such as Cisco Systems that can support 5 different types of interfaces, namely eia/tia-232 interface, eia/tia-449 interface, v.35 interface, x.21 Serial cable assembly and EIA-530 interface, corresponding to the adapter. It is important to note that, generally speaking, th

computers is the serial port, which now has at least two serial port COM1 and COM2. The serial port differs from the parallel port in that its data and control information is transmitted serially by one after another. In this way, although the speed is slower, but the transmission distance is longer than the parallel port, so long-distance communication should use a serial port. Typically, COM1 uses a 9-pin D-shaped connector, while COM2 some use an old-fashioned

configure a vro interface, you must enter the interface configuration mode of the vro. All configurations are only applied to this interface. Each configuration mode has a specific command prompt. EXEC provides a command interpretation service for IOS software. When each command is typed, EXEC will execute this command.Ii. Cisco router configurationWhen we configure a Cisco router for the first time, we need to configure it from the console port. The following describes how to connect to the co

have interfaces. Each Interface has its own name and number. The full name of an interface consists of its type mark and number, which starts from 0. For routers with fixed interfaces (such as Cisco 2500 series) or routers with modular interfaces (such as Cisco 4700 series), only one number is used in the full name of the interface, serial numbers are carried out based on the physical order of the routers. For example, Ethernet0 indicates 1st Ethernet interfaces and Serial1 indicates 2nd serial

from Flash 2. Preparations When designing a router product, the manufacturer reserves a Console. It is an important interface for vro configuration and the first step for password recovery: connect the terminal or PC with the Super Terminal software to the Console port of the vro by using the DB25 forwarding interface and crossover line. The terminal parameter settings are as follows: Speed: 9 600 bps; Data bit: 8; parity bit: none; stop bit: 1; tra

This article uses the Cisco 2509 Terminal Server to log on to other machines. how to configure the server? The following article describes the configuration process in detail and provides configuration commands. Use Cisco router reverse Telnet for Terminal Server If we have multiple routers for experiment, it will be very troublesome to configure one Router Based on the control line. Therefore, we need to configure a terminal server to log on to other machines, the procedure is as follows: In

This article describes how to quickly install and maintain a vro from the aspects of control port interface connection, initialization and installation, and troubleshooting and detection of common routing faults. See the detailed description below. A terminal or PC configured with a Cisco router must also use a valid power supply. Cisco synchronous serial interfaces are commonly used. Different interfaces can be obtained through different cables. Many may not know much about the installation and

A router is a commonly used network device. How do we install a router for beginners? How can I maintain a fault? The following article will give you a detailed answer. Installation steps: Step 1: control port connection First, connect one end of the control cable RJ45 in the CISCO2500/1000 series router accessories to the cisco console port, CISO7000/4000 Series routers connect one end of the DB25 of the MODEM cable to the cisco console port, and one

As the core device of network communication, Cisco routers are widely used. The following is my experience in practice: Control port interface practices and connections Connect one end of the control cable RJ45 in the Cisco2500/1000 series router accessories to the Cisco CONSOLE port, and the Cisco7000/4000 series router connects one end of the DB25 of the MODEM cable to the Cisco CONSOLE port, one end of DB9 is connected to COMl/2 of the PC. Set the

-232, RS-422 and RS-485 standards only to interface electrical characteristics to make provisions, and does not involve connectors, cables or protocols, on this basis, users can establish their own high-level communication protocols. The most frequently used plug-ins we encounter in our actual work have three DB9 DB25 RJ45 plug-ins. The above three plug-ins can be used as serial port plug-ins, you can also switch between sockets through cables. Next w
