Download the driver. When you plug Tira-2 into your computer the first time, Windows will not recognize it. This is so because Windows automatically searches an online database for generic drivers, however the required drivers do not exist there. You need to download the drivers manually. You can get them here.
After downloading the driver, you will have to extract the contents of the zip file to a temporary folder of your choice. To do this simply double click the zip file, and press "extract". Your extraction program will then ask you where you would like to extract the files to. Because these files are temporary, you can place them anywhere you want as long as you can remember its location later. The most convenient place is a folder on your desktop.
Now that you have the drivers, you will need to install them. If you have not already done so, please plug in your device. On some versions of windows an installation wizard may pop up, while on others it will not. Whether you receive the popup or not, you will have to manually direct windows to the folder where you extracted the drivers to previously. If you received a popup, please proceed to section A, if you have not received a popup, please proceed to section B.
If you received a popup from windows asking you what you want to do, select the manual installation option. This may be displayed as “locate and install driver software” or you may get a “Found new hardware wizard” if you are running an older version of windows. To install the drivers, follow the on-screen instructions until you are given the option of locating the drivers manually. Select that option, and direct Windows to the folder you extracted the drivers into previously. Repeat the process when a second popup appears to install drivers for the USB serial port. Direct it to the same folder as previously.
If you do not receive a popup, or Windows reports that it failed to automatically install the device, you will have to install it manually. To do so, you will need to open device manager (Windows XP: Right-click My Computer, click Manage, open Device Manager. Windows Vista: Click Start, and open Control Panel, locate and open System Maintenance, open device manager. Windows 7: Click Start, and open Control panel. Locate and open Device manager). In device manager, there will be an unrecognized device called Tira-2. This is the Tira device. Double click Tira-2. A Tira-2 Properties window will appear. There are three tabs at the top of the window, click the “drivers” tab. Proceed to click “Update Driver”. Follow the onscreen instructions, and point windows in the directory of the driver you have extracted previously, when you are prompted to do so.
After this is done, widows will recognise the Tira device as a Universal Serial Bus controller, however the driver installation is not complete yet. You will notice that there is now an unrecognized USB Serial Port.
Double click the USB Serial Port, and do the same as you did for the Tira-2 installation. Select “Update driver” and point it to the directory of the driver you have extracted previously. (The same directory you used for Tira-2 installation).
The Driver installation is now complete. You should see the “Tira IR Adapter” under Universal Serial Bus controllers and “Tira USB IR adapter (COM #)” under Ports (COM & LPT) in device manager. If you see both of these, your device is now recognized by windows, and is ready for programming.
