Configuring the USB Driver

NOTICE:
Always install the USB drivers prior to connecting the USB adaptor to the PC for this first time.   This way, when the interface is first connected it will automatically be detected and will not prompt you for a driver installation disk.

The USB drivers for the TTS interface are included on the distribution CD, and are installed by selecting the Prerequisites and Drivers button.   These can also be downloaded from the FTDI website at http://www.ftdichip.com/FTDrivers.htm.   When downloading, select the VCP (Virtual Com Port) driver type.

These drivers can also be installed by allowing Windows Update to search for them when the device is plugged in.   This will take a few minutes, so be patient!

Installing the USB Driver:
There are two different sets of drivers supplied for the TTS interface depending on your OS.   Windows 98 and ME use an older driver technology, and require a manual installation of the driver.   Windows 2000, XP, and Vista all use newer driver technology, and they are installed directly by pressing the USB Driver 2K / XP / Vista button.

Windows 98 / ME Install:
The Windows 98 driver install process is described in a PDF document which is viewed by pressing the USB Driver Win 98 / ME button.   Follow the instructions in section 2.2 for the FT245BM VCP device.   This will require that you connect the USB interface to the computer and when prompted by the Add New Hardware wizard, browse to the TTS installation CD directory "D:\USB_Drivers\Windows_98SE_ME" and enter OK.

Windows 2000 / XP / Vista / Win7 Install:
To install the drivers for the later OS, insert the TTS installation CD and browse to the Prerequisites and Drivers page.   Then, press the USB Driver 2K / XP / Vista button to invoke the install process.   This will automatically install the necessary drivers for all versions of these OS.   Installation may take a minute or two to complete.

Windows 2000 / XP / Vista / Win7 Install Failure:
If the automatic driver installation fails for any reason, the drivers can be installed using the manual process similar to windows 98.   In this case, connect the interface to the PC, and when prompted by the Add New Hardware wizard, browse to the TTS installation CD directory "D:\USB_Drivers\Windows_2000_XP_Vista\Unpacked-2.04.06" and enter OK.   Follow the wizard prompts to complete the installation process.

Configuring the USB Driver:
In some cases, it is necessary to reassign the COM port that the USB driver automatically selects.   MasterTune and DataMaster require the COM port be between COM1 and COM12, and sometimes this must be manually assigned.   The following sections show how to do this using Device Manager.

Notes:

1. You must be logged in as an administrator to make changes with Device manager!

2. The interface must be connected to the PC in order to perform the following configuration.

Tip:   A shortcut to access Device Manager is to open devmgmt.msc from the Start - Run dialog:

This will bring up the device manager dialog.   Go to the section labeled "Ports (COM & LPT)" and press on the "+" symbol to view the port assignments:

In this example, there are three COM ports shown.   This following example shows how to reassign COM11 to a new COM port number.

To reassign the COM port number, double click on the USB Serial Port selection to be changed.   This will bring up the driver configuration dialog.

Select the Port Settings tab, then press the "Advanced" button:   This will bring up the Advanced Port Settings dialog.   In this example, note COM1 through COM10 are already "In Use" by other devices.

The TTS USB port must be assigned between COM1 and COM12.   If all these port assignments are already in use, (which often happens with wireless laptops), make a new selection between COM5 and COM12 (COM1 - 4 are usually the Laptop hardware such as IR or Modem connections) - You will receive the following warning:

Click "Yes" to accept the new assignment.   This will generally not cause any problem - however the selection can be easily changed at a later time if necessary.

Make a note of the port number you selected, and select OK to apply the changes.   When you open MasterTune or DataMaster and select the serial Com port, use this port number.

1. You must be logged in as an administrator to make changes with Device manager!

2. The interface must be connected to the PC in order to perform the following configuration.

The Windows Device Manager application must be used to configure the USB serial port connection.   There are two ways to invoke device manager:

Type devmgmt.msc into the windows Search box:

-OR-
From the start menu, right-clicking on Computer and selecting Manage:

You will receive the message   "Windows needs your permission to continue".   Press the Continue button
Click on "Device Manager" in the left-hand tree:

The right hand pane will show a list of all devices.

Click on the "Ports (COM & LPT)" in the right hand pane.   This will show a list of all the available COM ports:

Double click on the USB Serial Port open the driver properties dialog:

Next, click on the "Port Settings" tab:

Now press the "Advanced" button to access the advanced port settings dialog.   From this dialog, select the new COM port number:

After this selection, press OK to save changes as you exit all the driver configuration dialogs.
