VGA Extender

Model: VB100VK

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:

z Passive device, no power required
z Includes VB100VK-T Transmitter unit and VB100VK-R Receiver unit
z Supports up to 1280x1024 pixels
z Distance up to 500ft / 135m via standard CAT5 STP or UTP cable instead of VGA cable
z Transmitter has built-in virtual DDC to avoid improper resolution and frequency settings
z Transmitter has built-in sync mode selection for signal stability
z 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.

RJ45 Pin Configuration: TIA/EIA 568B Wiring standard

UTP = Unshielded Twisted Pair / STP = Shielded Twisted Pair

Switch Setting:
VB100VK-T Sync Mode Select

← Mode 1

→ Mode 2

1. For newer monitors, Mode 1 is recommended for the best stability. If you experience
problems with the picture, switch to Mode 2.

2. For older monitors, Mode 2 is recommended. If the picture is still not stable, please try
adjusting the dip switches on the VB100VK-R Receiver unit. In the case that the dip
switches still do not fix the problem, please use STP (shielded twisted pair) cable.

The Sync Filter is designed for UTP CAT5 cabling. Sync Filter level adjustment adds sync
stability, but does not adjust picture quality or eliminate skew.
Since each monitor has different settings, there is no recommended setting. Please
adjust the level based on picture stability. If there is no picture display or if you experience
problems with the picture, please use STP cable.

Caution:

1. The wiring must be placed away from electromagnetic equipment, i.e. microwave, wireless,
high voltage cable…etc.

2. The maximum distances supported by the VGA Extender are dependent on the type of twisted
pair cable used and image resolution of the PC’s VGA interface. Make sure that the maximum
recommended operational distances have not been exceeded.

3. All wiring is “straight-through” twisted pair cable, and should not be used for other LAN or
telephone equipment.

4. Do not connect the VGA Extender to a telecommunication outlet wired to unrelated equipment.
