3 INSTALLATION OF THE DRIVER 
 
Mastervolt SCM Datacontrol USB Interface Driver 
software is available as free to download software 
on the Mastervolt website (www.mastervolt.com). 
Install the software on the desktop of your PC or 
notebook. 
Installation of the software depends on the operating 
systems used: 
Windows 2000, Windows XP, Vista. 
 
3.1 INSTALLING A DRIVER FOR THE SOLAR 
CHARGEMASTER INTERFACE 
3.1.1 Connection 
In order to install drivers, you must connect the Solar 
ChargeMaster Interface to a USB port of your 
computer. To install the interface driver it is not 
necessary to connect the Solar ChargeMaster to the 
interface. 
You only need to connect the interface cable with 
the USB port of your computer. 
For installing the drivers for the Solar ChargeMaster, 
use the installation guide on the CD-Rom. 
 
3.1.2 Operating systems 
This chapter provides users of the Solar 
ChargeMaster with a simple procedure for installing 
the driver for their Solar ChargeMaster on USB-
capable Windows based PC systems. Use the 
Subdirectory Windows 2000 if your PC is based on 
Windows 2000 Use the Subdirectory Windows XP if 
your PC is based on Windows XP. Please ensure 
that older installations of the driver have to be 
removed from the PC before the new driver is 
installed otherwise you will get a corrupt driver. 
 
3.1.3 Driver type 
The driver type is the virtual COM port (VCP) driver. 
The VCP drivers emulate a standard PC COM port. 
These can be communicated with in the same 
manner as any other COM port on the PC. 
 
3.2 INSTALLING FOR WINDOWS 2000 
Under Windows 2000, the Found New Hardware 
Wizard should be used to install devices when they 
are connected to the PC for the first time. Attempting 
other methods for installing VCP drivers may corrupt 
driver installation and result in the device becoming 
unusable with the installation PC. 
If a device of the same type has been installed on 
your machine before and the drivers that are about 
to be installed are different from those installed 
already, the original drivers need to be uninstalled. 
Please refer to the Uninstalling Solar ChargeMaster 
Device section of this document for further details of 
this procedure. 
• Download the latest available “Windows 2000” 
Solar ChargeMaster driver from the Mastervolt web 
site or from your Mastervolt CD and unzip them to a 
location on your PC (e.g. C:/MastervoltDriver). 
• Connect the device to a spare USB port on your 
PC. This will launch the Windows Found New 
Hardware Wizard. To proceed with the installation 
click “Next”. 
Select “Install from a list or specific location 
(Advanced)” and then click “Next”. 
 Check the box next to “Specify a location” and 
uncheck all others. 
• Clicking “Next” displays a dialog box for you to 
enter the location of the drivers. 
• Click “Browse” to display an open file dialog box. 
Locate the folder containing the latest drivers 
downloaded from the Solar ChargeMaster website or 
the Mastervolt CD above and click “Open”, then click 
“OK”. Once Windows has found the required driver 
.INF file, click “Next” to proceed. 
• Windows should then display a message indicating 
that the installation was successful. Click “Finish” to 
complete the installation. You now have installed the 
serial converter. The COM port emulation driver 
must be installed after this installation. 
• After clicking “Finish”, the Found New Hardware 
Wizard will continue by installing the COM port 
emulation driver. The procedure is the same as that 
above for installing the serial converter driver. 
• Open the Device Manager (located in “Control 
Panel\System” then select the “Hardware” tab and 
click “Device Manger…”), the device appears as an 
additional COM port with the label “Solar 
ChargeMaster Port”.
