Connect My Usb Device
The various USB interface modules made by Technological Arts are based on the popular FTDI chip FT232RL. Usually, Windows will recognize them when you plug them into a USB port on your computer.
If it doesn't, you will need to download and install the appropriate driver from the FTDI website. Drivers are provided for various versions of Windows. Download and install the correct version for your computer’s configuration before proceeding.Now connect a USB cable between a USB port on your PC and the USB interface module you are using. Windows should report a new device has been found and proceed to initialize it.
To determine which virtual COMport it has been assigned to, right click the MyComputer icon on your Windows desktop, and select Properties from the popup menu. Next, click on the Hardware tab, and click on the Device Manager button. Click OK, and if Windows warns you about a duplicate, ignore the warning and click Yes. Click OK and then OK to the port settings. Then close the Device Manager window.
If you want to confirm the port change has indeed been made, click on Device Manager again and check the listed Ports. Now close the System Properties window.At this point, you are ready to use the virtual COM port in any application!Note that, if you unplug the USB device and plug it back in later, Windows will still remember the COM port assignment, so you won't need to go through this procedure again.
However, there is a known Windows issue that affects most applications. The virtual COM port will be removed from the device manager when the USB cable is unplugged, even if an application has the virtual COM port open. The virtual COM port will not be accessible even after the virtual serial device is reconnected unless the virtual COM port is released by the application prior to the reconnection, which may require closing the application first. It is therefore recommended that the application be closed before the USB device is unplugged.
Plugging in a USB device is as simple as plugging it in (though sometimes you have to load software first). You can often remove USB devices from the computer without causing harm by merely pulling the cable out of the jack.Sometimes, however, you need to let your Mac know before you pull out the cable. To remove an iPod connected by USB, for example, your Mac wants you to click a tiny little icon in the iTunes software source list, next to the name you’ve assigned the portable music player. Failure to click the icon can cause unpleasant consequences.If you plug a USB device into a port in the keyboard and it doesn’t work, try plugging it into a USB port directly on the back or side of the computer.USB generally works great. But given all the devices that use USB, you may run out of available ports. In that case, you can buy a USB expansion hub — preferably one that you can plug in to an electrical outlet.The state of the art for USB ports is USB 2.0. Older Macs have slower USB 1.1 ports.
