INTRODUCTION  
Congratulations on your purchase of the Extender for DVI and RS232 Over One  
Fiber Optic Cable. Your complete satisfaction is very important to us.  
Gefen  
Gefen delivers innovative, progressive computer and electronics add-on solutions  
that harness integration, extension, distribution and conversion technologies.

The Gefen Extender for DVI and RS232 Over One Fiber Optic Cable  
The Extender for DVI and RS232 over One Fiber Optic cable is a complete  
solution allowing DVI and RS-232 to be extended to a monitor, touch-screen  
display, or other DVI device up to 1640 feet (500 meters) from the source.  
A single strand SC fiber optic cable is used for the long distance extension,  
providing excellent protection from background electromagnetic interference  
(EMI), preserving both DVI and RS-232 signal integrity. Locking DVI, RS-232,  
and power connectors ensure secure connections.  
How It Works  
The Sender unit is placed near the DVI source and the Receiver unit near the  
Display. Connect the supplied DVI cable between the Sender unit and the DVI  
source. Connect a second DVI cable between the Receiver unit and the display.  
Connect the RS-232 cable from the RS-232 source to the Sender unit. Connect  
the RS-232 cable between the Receiver unit and the RS-232 connection on the  
display side. Connect a single strand of multi-mode SC-terminated fiber optic  
cable between the Sender and Receiver unit. Connect the power supplies to both  
the Sender and Reciever unit.
