What is a Null Modem Converter?
A Null Modem Converter is a simple device used to connect two computers directly to each other, using their serial ports. It essentially makes a virtual connection between the two computers, allowing them to communicate as if they were connected through a network. The term “Null Modem” comes from the fact that it is a modem without any modulating or demodulating functionality, which means it does not alter the data being transmitted.
How does a Null Modem Converter work?
A Null Modem Converter works by connecting two devices through their serial ports with a cable that uses a crossed transmission line. This means that the receive line of one device is connected to the transmit line of the other, and vice versa. This allows the two devices to send and receive data from each other. Without a Null Modem Converter, serial communication can only occur between a computer and a peripheral device, such as a printer or scanner.
What are the advantages of using a Null Modem Converter?
There are several advantages to using a Null Modem Converter. For one, it eliminates the need for a network or additional hardware to connect two computers. It also allows for faster data transfer rates than most other forms of direct connection between two computers. Additionally, it provides a simple way to transfer data without having to use a physical storage device, such as a USB drive or external hard drive.
What are some practical uses for a Null Modem Converter?
A Null Modem Converter can be useful in several scenarios. For example, it can be used to transfer data between two computers that are not connected to the internet or a network, or to troubleshoot issues with serial port devices and connections. It can also be used to access devices remotely, such as when supporting a customer's computer system, without requiring them to set up a network connection.
What types of cables are used with a Null Modem Converter?
Null Modem Converters typically use serial cables, which come in two types: DB9 and DB25. The type of cable required is dependent on the type of connector on each device. It is important to ensure that the correct type of cable is used to avoid any compatibility issues.
How do you install a Null Modem Converter?
Installing a Null Modem Converter is a simple process. First, connect the converter to both devices using the appropriate serial cable. Next, ensure that the devices are set up correctly for serial communication. This may require making changes to BIOS settings or operating system configuration. Once everything is set up as needed, the devices should be able to communicate with each other.
What should you consider before buying a Null Modem Converter?
Before purchasing a Null Modem Converter, there are a few things to consider. First, ensure that the converter is compatible with the devices you wish to connect. Additionally, consider the maximum transmission speed, as this will determine the maximum speed at which data can be transferred. Finally, consider the length of the serial cable required, as longer cables can cause signal degradation and loss of data.
In Conclusion
A Null Modem Converter is a useful device for anyone who needs to connect two computers directly to each other without using a network. It offers faster data transfer rates than most methods of direct connection, as well as providing a simple way to transfer data without using physical storage devices.
