The VGA Extender allows VGA video signals to be transmitted up to 500ft / 135m via 4-pairs CAT5
STP or UTP cable. Used in pairs, the VGA Extender can be used in home or commercial applications
as a smart, fast and cost-effective solution. It eliminates costly and bulky VGA cable, allowing VGA
monitors to be connected extended distances from the PC via standard twisted pair cable. This
product is ideal for classrooms, lecture halls, retail kiosks, video information displays, overhead
projector systems, PC-training systems, and tradeshows PC demo systems.
Features:
Passive device, no power required
Includes VB100VK-T Transmitter unit and VB100VK-R Receiver unit
Supports up to 1280x1024 pixels
Distance up to 500ft / 135m via standard CAT5 STP or UTP cable instead of VGA cable
Transmitter has built-in virtual DDC to avoid improper resolution and frequency settings
Transmitter has built-in sync mode selection for signal stability
Receiver has built-in sync filter level adjustment for signal stability
Installation:
Recommended Cable:
1. CAT5e UTP/STP or CAT6 UTP cable.
2. Certain brands or models of monitors are highly sync-sensitive. In these cases we recommend
using STP (shielded twisted pair) cable instead of UTP (unshielded twisted pair) cable.
