Handbook for the TRIUS SX-825      Issue 1 January 2015 

 

 

You will also need a PC computer with Windows XP, Vista or Windows 7 installed. This machine 
must have at least one USB 2.0 port available and at least 256 Mbytes of memory. If you intend to 
view the finished images on its screen, then you will also need a graphics card capable of displaying an 
image with a minimum of 1024 x 768 pixels and 24 bit colour. A medium specification Pentium with 
between 1GHz and 4GHz processor speed is ideal, but I recommend avoiding some of the lower 
specification ‘Netbook’ computers, as they can’t really handle the fast data stream from the camera. 
Please note that USB 2.0 operates at a very high speed and cannot operate over very long cables. Five 
metres of good quality cable is the maximum normally possible without boosters or extra powered 
hubs, although you can sometimes get good results at longer distances with very high quality cables.  
 
 

Installing the USB system: 

 
First, find a free USB socket on your PC and plug in the USB cable (do not connect the camera at this 
time). If you do not have a USB2 capable computer, it is normally possible to install a USB 2 card into 
an expansion slot.  
 
The next operation is to run the software installer from the CD ROM provided. Insert the CD into the 
computer and wait for Windows Explorer to open with the list of folders on the ROM. Now run the 
SETUP.EXE file that it contains – this will initiate the self-install software which will guide you 
through the process of installing the SX camera software onto your computer.  
 
Now connect the USB cable to the socket on the camera rear panel.  
 

 

 
 
Windows will report ‘Found new hardware’ and will ask for the location of the drivers. Point the 
installer at the appropriate driver folder on your CD ROM (32 bit or 64 bit) - note that the ‘Windows 8 
signed drivers’ are OK for Windows 8, Windows 7 and Vista, but not for Windows XP. Use the older 
32 or 64 bit drivers for XP machines. Once you select the correct driver package, the driver installation 
should proceed smoothly. (Ignore any warnings about the older drivers having not been tested by 
Microsoft).
