The Gyro devices require a TTL (5V) interface with the PC.Tarot and CopterX have adapters available which allow you to use a USB port on your Windows PC to communicate with the Gyro.
You should be able to use the same principals to connect using other adapters.
To use your Tarot adapter, you should install the USB driver called ZYXUSBdriver.exe found in the driver folder of the Tarot software installation.
You should install this driver before plugging the USB adapter into your PC. You only need to install the driver once.
Once you have installed the driver you can plug in the USB adapter. Windows will detect the USB adapter and assign it a COM port.
The following section describes how to tell which COM port has been assigned and how to change the port if necessary.
First unplug your USB adapter.
Start your device manager.
You will see a window similar to the following
Expand the section Ports (COM & LPT), you will see the existing ports on your PC, similar to the following
Note the existing ports. Now plug in your adapter
When you plug the adapter, Windows may collapse the Ports (COM & LPT) section again.
If it does, expand it again and you will see the new port
In this case, windows has assigned the adapter to COM7.
If you are using the FBL software, select this port before connecting the software.
If you are using the Tarot software, you will need to reassign the port to a number of 4 or less.
Since in this example we already have COM1 and COM2 in use, we will need to reassign COM3 or COM4.
To do this, right click the entry in the device manager and select 'Properties' You will then see a window as follows
Click on the port settings tab and then click on advanced.
At the bottom of the advanced menu you can select another COM port.
Select the port you wish to use from the list. If it is marked as 'in use', you may still select that port. It is okay to do this if the port is not presently in the 'Ports (COM & LPT) section.
If the port is in use, you will get a warning, just press YES to accept the change.
Press OK to accept the new settings.
It pays at this point to disconnect the USB port and then plug it again.
You should be able to check that it is now the newly assigned port number.
You can now close the device manager window and run the FBL or Tarot software.
