We’ve finished installing the drivers but now we need to bind them to 
the ST-402.  Quit the 

Driver Checker

 by clicking the 

 

X  

in the upper-

right hand corner.  If you’re running 

Windows XP

 then continue with 

step 7

 below.  Users of older versions of Windows should now look for 

instructions particular to their version of Windows in the “

Installing 

USB Drivers

” Application Note that can be found on the CD-ROM or 

our web site. 

7.

 

Now’s the moment you’ve been waiting for.  We’re going to plug the 
camera into the computer, but not so fast! 
     First plug the camera into the power source and note that the 

Fan

 

comes on but the 

Red LED

 does not.  The ST-402 actually has its 

internal firmware downloaded to it by the PC at startup.  If the 

LED is 

off

 the camera has not been 

booted

.  Please remember that. 

     Now plug the camera into the USB port on the computer with the 
supplied USB cable.  

Remember

 which port you’re using because 

you’ll want to use the 

same port

 again next time or you’ll have to go 

through this process of binding the drivers all over again.  Windows 
will crunch for a while and then present you with the 

Found New 

Hardware Wizard

 (

Wizard

) dialog. 

 

8.

 

If you’re asked if it should connect to 

Windows Update

 to search for 

software click “

No, not this time

”, then click 

Next

 

9.

 

Now the 

Wizard

 will ask you if you want to install the software 

automatically.  Select to do so then click 

Next

 

10.

 

Windows will grind for a while copying the 

SBIG ST-402 Loader

 

driver then show you the 

Completing the Found New Hardware 

Wizard

 page. 

     Click 

Finish

.  At this point the 

Red LED

 on the back of the camera 

should be on, and if you had been watching it you would have seen it 

blink

 several times while the PC was 

booting the camera

After booting the camera Windows will bring up another copy of the 

Wizard

.  The ST-402 actually uses 

two drivers

.  One to 

boot

 the camera 

and one to 

talk to it

 after it’s booted.  We now need to walk 

Windows

 

through installing the second driver. 

12.

 

Repeat steps 8 and 9, again telling the 

FNHW

 to not check for updates 

and to install automatically.  At this point windows will show you the

Select the 

oem

 file not the 

sbig

 file (the second item above) by clicking 

on it then click the 

Next

 button. 

14.

 

Windows will grind one last time copying the 

SBIG USB Camera

 

driver then show you the 

Completing the Found New Hardware 

Wizard

 page. 

     Click the 

Finish

 button and 

pat your 

self on the back

.  You’re done! 

 
If you ever doubt that the camera is actually connected you can open the 

Device Manager

 from the 

Hardware

 tab of the 

System

 control panel and 

expand the 

Universal Serial Bus controllers

 section.  You should see a 

SBIG USB Camera

 listed there: 

 

While you’ve got the 

System

 Control Panel open, if you want to restore the 

Windows Driver Signing security check, click the 

Hardware

 tab, click the 

Driver Signing

 button and select: 

 

If Windows can not automatically find the drivers , tell it to Install from a 
Specific Location and then browse to the folder: 

C:\Program Files\SBIG\Driver Checker\SBIG Drivers
