Two-machine interconnection refers to the direct connection of two computers, enabling them to communicate and share resources. This can be achieved through various methods such as network card connections, serial port, parallel port, Modem, infrared, and USB. In this article, we will focus on how to use a USB cable for two-machine interconnection.
USB-based two-machine interconnection is a convenient and efficient way to connect two computers without the need for a traditional network card. It offers a data transfer speed of up to 15 Mbps and allows for remote PC detection. Users can easily copy, paste, or drag files between two windows, and even print documents from a remote computer using a local printer. Additionally, it supports hot-plugging and remote wake-up features, with a transmission range of approximately 5 meters. However, one limitation is that the USB network cable cannot function if the server is not powered on, and its scalability is limited compared to traditional networking solutions. Still, it is more than sufficient for basic file sharing between two machines.
USB network cables can also be connected to multiple computers via a USB hub, though this increases the chances of disconnection or instability. The performance-to-price ratio is similar to that of a real network card, but the need for driver installation makes the process less user-friendly.
There are two main types of USB cables available in the market:
1) **USB Direct Connection Cable**: Primarily used for transferring files.
2) **USB Network Cable**: Offers full network functionality, including file sharing, online gaming, and shared Internet access.
For two-machine interconnection, it's recommended to use the USB network cable. A single USB network cable essentially functions like two network cards and a network cable combined. Although this method has been around for some time, it's still considered non-mainstream. With the widespread availability of USB ports on both desktops and laptops, using a USB network cable is now a simple solution for home users.
It's important to note that standard USB cables should not be used for dual-machine connections, as they may damage the USB ports or even the motherboard. Instead, a special USB network cable with an embedded chip is required for proper communication between the two machines.
USB network cables come in different versions, such as USB 1.1 and USB 2.0. USB 1.1 provides a maximum transfer rate of 12 Mbps, while USB 2.0 can reach up to 480 Mbps. Although the theoretical speed of USB 2.0 is much higher, most products today only achieve around 15 MB/s. For better performance, it’s advisable to choose a USB 2.0 network cable, especially if your motherboard supports it. If not, you can use an external PCI-to-USB 2.0 adapter card, which is commonly available with VIA USB 2.0 controllers.
To set up two computers using a USB network cable, follow these steps:
1. **Install the Driver**: Insert the driver CD provided with the cable and install the software. Make sure to enable the USB option in the BIOS before booting. After installation, restart the system if needed.
2. **Configure the Network Settings**: On the server computer, go to "Network Connections" and set the IP address to 192.168.0.1 with a subnet mask of 255.255.255.0. Repeat the same steps on the client, setting the IP to 192.168.0.2 and the default gateway to 192.168.0.1.
3. **Share Files and Resources**: Once the network is set up, use software like PC-Linq to access and manage files on the remote machine. You can copy, delete, or move files directly between the two systems. PC-Linq also allows access to CD-ROM drives and shared printing capabilities.
When using this setup, always close the PC-Linq application before unplugging the USB cable to avoid system crashes or blue screens. Be cautious when deleting files, as accidental deletion can lead to data loss.
In summary, USB-based two-machine interconnection is a flexible, fast, and cost-effective solution for connecting two computers. It supports file, device, and print sharing, as well as Internet access. Its plug-and-play nature makes it ideal for laptop users who need a portable and easy-to-use networking solution.
