Intelix AVO-VGA 

Installation Manual 

 
 

 

 
Introduction 

The Intelix AVO-VGA balun set transmits VGA video passively over standard unshielded 
twisted pair cable, such as Cat 5, Cat 5e or Cat 6. The AVO-VGA eliminates costly and 
bulky VGA cable, and extends video transmission distances.  

 

Pre-Installation

 

 
 
 
 
 

 

The AVO-VGA features shielded RJ45 connectors, which are provided as an option in 
harsh electrical environments, such as installations with large motors or cable runs 
near sources of interference

. In such environments, shielded twisted pair cable (STP) may 

provide additional noise immunity. When using STP, ensure the shield on both ends of the 
cable run is terminated to a shielded RJ45 connector. 

 

 
 

Note:

 The AVO-VGA does not support VGA handshaking and control signals. 

Therefore, it is necessary to set the monitor attributes prior to installing the balun set. 
First connect the source (typically a computer) directly to the destination (typically a
monitor) with a standard VGA cable. After doing so, set the monitor attributes to the 
required settings (i.e., resolution, color, etc.). For best results, also set the contrast and 
brightness to the maximum level. 

Caution:

 Do not attempt to disassemble or alter the balun housing. There are no 

user-serviceable parts inside the unit. Doing so will void your warranty.
