Three Hardware Devices for Internet Connection and Server Access

The Internet is nothing short of a miracle realm. With sufficient speed and connection stability, you can download or upload a steady stream of information – without losing a bit of it. This is made possible through powerful terminal servers. Technically terminal servers are very simple devices that offer no security or functionality such as user authentication and data encryption. One example is Digit 70001527 Etherlite 16 Terminal Server w/power supply, a product that can be found on our ecommerce site here. This device, like other terminal servers, enables organizations to connect devices with an RS-485, RS-422 or RS-232 serial interface to local area networks (LAN). The use of a terminal server means that each terminal on the network doesn’t need its own network interface card or modem. Some terminal servers can handle 128 terminals.

A terminal server’s primary application is to allow serial devices to gain access to network server applications, and vice versa, where data security is not issue. The market currently abounds in terminal servers with advanced security functions; this ensures that all data transmitted across a LAN is encrypted, and that only qualified personnel can access specific servers.

Digi Terminal Servers

Historically, terminal servers trace their roots from Digital Equipment Corporation, an American computer systems provider. This company, which was later acquired by Compaq, created other terminal servers. Examples of DEC’s products are the DECserver100, DECserver 200, and DECserver 300.

Aside from the Digi 70001527 Etherlite terminal server, internet access and speed can also be improved through a Digi 77000012 Com/8i XI ISA 8 port. Like all serial ports, this model acts as a physical interface for serial communication, through which information is transferred one bit at a time. The term serial port is usually identified with hardware that complies with RS-232. RS-232 is the traditional name for a series of standards for serial binary single-ended data and control signals commonly used in serial ports.

In the past, an RS-232 port was a standard feature of PCs which allows them to connect to printers, modems, data storage and other peripheral devices. However, RS-232 ports were hampered by problems like limited transmission speeds, large standard connectors, and large voltage swings. This prompted manufacturers to replace them with a “universal serial bus”.

With devices such as the Eltek H2500A2-VV Eltek Valere 48v 50a H Series Rectifiers, the triad in providing superb internet connection is complete. Like all rectifiers, this product works by converting alternating current (AC) to direct current (DC) through a process called “rectification”. Using these devices, you can expect internet and network access to be faster and easier.
