Cabling Systems & Solutions UTP = Unshielded Twisted Pair / STP = Shielded Twisted Pair
Rev102007 VGE01
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:
zPassive device, no power required
zIncludes VB100VK-T Transmitter unit and VB100VK-R Receiver unit
zSupports up to 1280x1024 pixels
zDistance up to 500ft / 135m via standard CAT5 STP or UTP cable instead of VGA cable
zTransmitter has built-in virtual DDC to avoid improper resolution and frequency settings
zTransmitter has built-in sync mode selection for signal stability
zReceiver 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.

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.

Troubleshooting picture problems:
1. No picture display:
Check Link cable
Check DIP switch setting
Check VGA cable connection
Change the resolution or frequency
Change Link cable for STP cable
2. Picture not stable or disappear intermittence or no picture display:
Check DIP switch setting
Change the resolution or frequency
Place wiring away from electromagnetic equipment
Change Link cable for STP cable
3. Picture tilt:
Check DIP switch setting
Change the resolution or frequency
Change Link cable for STP cable

Application Tips to use CAT5 STP cable:
The following is the correct cable connection when using STP cable:
1. STP (shielded twisted pair) Cable.
Max. Distance via CAT5 Cable
640x480 pixels (15MHz) 500ft / 135m
800x600 pixels (30MHz) 350ft / 105m
1024x768 pixels (60MHz) 250ft / 75m
1280x1024 pixels (100MHz) 200ft / 60m

2. STP (shielded) RJ45 connector with STP cable connection.
If your RJ45 connector has plastic housing (unshielded), then the cable connection must
be configured as follows:
1. The ground cable must be pulled out around 5-10cm to connect with the VGA Extender’s
ground screw for grounding.
2. Connect the ground cable to the ground screw, and then plug in the RJ45 connector.
