Usb serial adaptor
USB serial adopter is a device that used to connect the different types of serial devices to the computer or the PC. The USB serial adopter provides high speed for the data transfer. This is the why it is concerned as one of the most inexpensive, simple and the reliable sources to get the serial devices connected to the computer. The USB serial adopter can be used efficiently with the digital cameras, modems, graphic tablets, ISDN terminal adopters, Bar code scanners, label printers, PDA and other such devices. So, the USB serial adopter finds use in many types of devices. It can also be used in any type of device that requires the RS-232 connection. Let us now discuss how the USB serial adopter works.
How Usb serial adopter works
There are many types of USB serial adopters that are available in the market. The principal of working is the same. The USB serial adopter is plugged into the USB port provided in the computer that has windows installed or in the Macintosh computer. It also has one male DB9 port. This port is provided in order to make the direct connection to the serial devices. The USB serial adopter is connected by means of a USB cable and the length of this USB cable varies from one manufacturer to another manufacturer. Normally, the length of this cord is three feet. As said above also, the USB serial adopter supports the high-speed data transfer and the speed can be up to 230 Kbps. It is to be noted here that this speed is two times the speed that is provided by the standard serial ports provided in the computer. Most of the USB serial adopters work on the basis of Plug and Play installation. Thus, there is no need of loading it. All the USB serial adopters are 100% USB compliant. The power for the working of the USB serial adopter is drawn from the USB connection. This also eliminates the need for the power adopter. Given above is the explanation on the working of the USB serial adopter.
Related aspects of Usb serial adopter
There are many related aspects of the USB serial adopter that have to be understood. As said above also, the features of different types of adopter are different, but the principle is same. All the USB serial adopters are useful for all those computers that have a COM serial port and are used by some peripheral device. Similarly, it is very useful for those computers that have no COM port at all. When a person buys a serial adopter, he must also buy the USB cord that is compatible with the USB serial adopter purchased. All the USB serial adopters are provided with the drivers, manuals and the installation utilities and thus, while buying, these must be checked. These serial adopters can easily work with all the planetarium programs. As far as the warranty is concerned, most of the USB Serial adopters come with five years warranty. For example, when a person buys the USB serial adopter from KEYSPAN, he gets five years warranty.
Many times a person gets confused about the termination resistors. He doesn\'t know when these have to be used. It is to be understood in the above regard that most of the USB serial adopters have factory installed termination resistors and thus, there is no need of installing them. The termination desired can easily be removed or selected by way of configuration of the associated jumper. This jumper is provided for each port. It is to be noted here that in most of the factory provided termination resistors, the default configuration is "no termination". As far as the default operation mode of the USB serial adopters is concerned, these adopters operate in Full Duplex mode. This default mode has been set by factory. If a person wishes to change the COM port numbers that are assigned to the USB serial adopters by the operating system like windows, he can easily change it.
There are some steps that have to be followed. These steps involve getting to device manager and clicking on the properties of the COM port that is to be changed. By selecting the settings and then advanced option, a person can easily get the drop down list. From this list, he can select the COM port number he wants to use. This allows him the desired port number. When a person plugs the USB adopter into another port or hub, he would get the new COM port numbers. In order to keep the same COM port number, a person must plug into the same port. In case a person wishes to configure each port on his USB Serial adopter by means of advanced option in the windows, he cannot do that, as any change in the settings in advanced options will of course affect all the ports that are there in the USB serial adopter. Thus, a person should not try to do this. Similarly, it is not possible to change the properties of the various ports that are there on USB serial adopter by means of the software provided with the USB serial adopter. This can be done only by the device manager option.
When the different types of applications are active, the USB serial adopter must not be unplugged as doing that may require a person to reboot the computer. For installing a USB serial adopter, a person must go through the instructions provided with the USB serial adopter.
Thus, Usb serial adopters are useful
After going through the above discussion, it can be rightly said that USB serial adopter is a very important device. It allows a person to use the different types of peripheral devices with his personal computer or a laptop. The speed provided by the USB serial adopter is almost double the speed of the Standard port on the computer. There are of course some aspects related to the USB serial adopters that have to be understood in order to use the device properly. Some precautions, as mentioned above, have to be taken for making changes in the configuration of the serial adopter.
