Every computer and electronic specialist know what a null modem adapter is. But for benefit of every layman out there, I will give a brief description of a this adapter. It is a small device used to connect one PC to another through their communication ports or modem protocol. This communication is effected by the help of a serial cable known as the null modem cable. With a combination of the null modem adapter and a network cable, one can achieve lasting efficient connectivity in various working environment. Null Modem Adapters Importance This is a very useful and popular device when it comes to linking serial devices together. Although today, its popularity is gradually waning, but this is due to new innovations in technology and not because of ineffectiveness. Another function of the this adapters is, they can be employed to resolve any problem encountered during the connection of two serial devices. They come in two types; the male and the female adapter. Both of these come in two forms: a 9-pin null modem adapter (db 9 connector) and a 25-pin null modem connector (db 25 connector); both having 9 and 25 pins respectively in the father and mother connectors. The adapter is so vital that when used with a serial cable, system users can work with their connectivity confidently without any Ethernet upgrade. Despite the speed of Ethernet, it’s unnecessary to set it up for communication in your system as long as the null modem adapter is present. Simply ensure the adapter is connected to the computer using quality cables for maximum efficiency. Uses It can be used to set up and manage a wide range of applications such as the rack-mount servers, the managed switches and even kernel mode developments in the various embedded systems.

It has to be the right one as different adapters are required for different set-up types. Knowing the right adapter will definitely enhance the performance of your set up. These adapters also play a vital role when using straight serial cables. In this case, the cross-links in the device make it possible for signals to cross-link effectively in case there are handshakes. Types There are several types of null modems. These include no hardware handshaking, loop-back handshaking, partial handshaking, full handshaking and the virtual null modem. Each of these has its own peculiar functions. Conclusion The Null Modem Adapter remains a useful device though due to the current cutting-edge technologies, many think that these adapters are antiquated. The truth is that most of them are still very much in use but their names have been changed. For more details and purchase of these adapters and many other, visit the website, www.sfcable.com.
