Standard modem type

A modem is a type of computer hardware that translates a computer's digital signals into analog signals that can be transmitted along a regular telephone line, which in turn can be received by another modem at the other end of the line and translated into a computer-readable language. . This simple process completes the communication between the two computers.

The external Modem external Modem is placed outside the chassis and connected to the host through the serial communication port. This Modem is easy to install and easy to install. The flashing indicator light makes it easy to monitor the working status of the Modem. However, an external modem requires additional power and cable. Built-in Modem internal modem (6 photos) Built-in Modem needs to be disassembled during installation, and the terminal and COM port are set up, which is cumbersome to install. This Modem takes up the expansion slot on the motherboard, but does not require additional power and cable, and the price is cheaper than the external Modem. The PCMCIA plug-in card modem is mainly used in notebook computers and is compact. With mobile phones, mobile office can be easily implemented. Rack Modem Rack Modem is equivalent to concentrating a group of Modems in a single box or enclosure and is powered by a unified power source. Rack Modem is mainly used in the central computer room of Internet/Intranet, telecommunication bureau, campus network, financial institution and other networks. Rack-mount modems (12 photos) In addition to the above four common modems, there are now ISDN modems and a modem called Cable Modem, in addition to an ADSL modem. Cable Modem uses cable TV cable for signal transmission. It not only has modem and demodulation functions, but also integrates routers, hubs and bridges. The theoretical transmission speed can reach more than 10Mbps. Through Cable Modem, each user has a separate IP address, which is equivalent to having a personal line. Shenzhen Cable TV Tianwei Network Co., Ltd. has launched this Internet access service based on cable TV network, with an access rate of 2Mbps-10Mbps!

1200V DC Electronic Load System

1200V DC Electronic Load System has battery discharge function, and can perform discharge test under CC, CR or CP mode. The DC load can set end voltage or time to stop loading correctly and make sure the battery is not damaged due to over discharge. The user can set stop conditions, whenever met any condition, the load will stop loading and counting automatically. During the test, users can observe battery's voltage, discharging time and already-discharged-capacity.1200V DC Electronic Load system including 39600W/52800W/66000W.BTW,if the 1200V is too big voltage for application,it can also choose lower 200V DC Electronic Load System and higher 1200V DC Electronic Load System .
