-pin serial port function is shown in table 1.* Db25 (25-pin socket), 3. The 25-pin serial port function is shown in table 2.* Another type of plug-in port is RJ45. For example, The SNI high mss1600 and mss700 Video Server encoding and decoding board control ports used by Hubei TV station are all serial ports. The plug-in ports are RJ45 and the serial port of the broadcasting controller is DB9, therefore, w

is similar to the RJ-11 telephone line in shape and exterior, but wider, due to the difference in size between the two (for 4 or 6-pin, RJ45 for 8-pin connectors ), obviously, the RJ45 plug cannot be inserted into the jack. In turn, it is physically feasible (the plug is smaller than the RJ45 jack), which makes people mistakenly think that the two should or can

RS422/RS485 BUS Model Analysis and Application [Date:] Source: China Power Grid Author: Li Deqing, Song Bin [Font: large, medium, and small] 　 0 Introduction RS422/RS485 bus interface, as an electrical specification for multi-point and differential data transmission, has become one of the more widely used standard communication interfaces in the industry.

Description of RS232/RS485/rs422 Interface Converter The DMUs series converter is a standard RS232/RS485/rs422 converter that completes the electrical conversion between the serial RS232 and RS485/rs422, and can extend the maximum communication distance to 1200 meters (4000 feet ). DMUs adopt the basic three-line system (txd, rxd, Gnd). No software driver is

Application of RJ45 short circuit ring on gigabit Nic1. Topic OriginFor those who often work on multiple operating systems, using Windows as the host system with Vmware Workstation is already a standard Workstation. I personally traveled back and forth between Windows and Linux and used the notebook configuration as Windows 7 as the host, VMWare Workstation 9 to install the Virtual Machine CentOS and OpenBSD. Virtual Machine network connection is set

common noise and can not suppress common mode interference and other problems, so it is generally used for communications within 20 m. 2. RS-485 RS-485 bus, when the communication distance is dozens of meters to kilometers, widely used RS-485Serial Bus. The RS-485 adopts balanced transmission and differential reception, so it has the ability to suppress common mode interference. In addition, the bus transceiver is highly sensitive and can detect voltage as low as 200mV. Therefore, the transmi

The RJ45 interface is typically used for data transmission, and the most common application is the NIC interface. RJ45 is a type of different joints; RJ45 head According to the order of the line there are two different ways, one is orange white, orange, green, blue, blue, white, green, brown, Brown, the other is green, white, green, orange, blue, blue, white, or

Both RS232 and RS422 are widely used asynchronous serial interface standards. Because they are simple to implement and consume less resources in IO ports, it is a good idea to transfer at low speed.The RS232 is a single-ended route with a maximum baud rate of 115200 and a transmission distance of no more than 150 meters, with a logic 1 level of 3 to -15v and a logic 0 level of 3 to 15V.The RS422 is a differ

Let's talk about the playing style and Tactics of RJ45 line sequence. The wiring standards of EIA/TIA define the line sequence 568a and 568b of the two twisted pair wires.568a standard:Green white -- 1, green -- 2, orange white -- 3, blue -- 4, blue white -- 5, orange -- 6, brown white -- 7, brown -- 8568b standard:Orange white -- 1, orange -- 2, green white -- 3, blue -- 4, blue white -- 5, green -- 6, brown white -- 7, brown -- 8 Note:568a:Green

We know that the cable is the basis of the network, if you do not well identify the use of the cable, you will not become a qualified engineer.The BNC cable is the copper shaft cable that we use for CCTV, which is used today as a signal input/output probe in an oscilloscope, although the appearance and the traditional cable are somewhat different, but the function is similar. It is mainly used in the network between the operator optical end machine to the router this link, is commonly known as t

However, when the author recently used a 10 m direct connection method (switching between 1 and 3, 2 and 6, and shielding the other four lines) to connect the network cable, unexpectedly, it was found that the Network was being transmitte

When dealing with computer networks, it is inevitable that network cables should be used frequently. In fact, the production of Network cables is very simple, that is, to insert the 4-to-8-Core Cable of twisted pair wires into the crystal head
