Oki VB100VK Instruction Manual

VGA Extender

Model: VB100VK

Features:

• The VGA Extender allows VGA video signals to be transmitted up to 500ft / 135m via 4-pairs CAT5
shielded twisted pairs cable.

• Included as a pair.

• 1 x VGA connector to RJ45 female.

• Up to 500ft / 135m via standard 4 pairs CAT 5 STP cable instead of VGA cable.

• Supports up to 1280x1024 pixels at 200ft / 60m.

• Passive device; Not supported by VGA DDC protocol.

• Perfect for classrooms, lecture halls, tradeshows, video information displays…etc.

• Used in pairs, the VGA Extender is used in the home or for commercial applications as a smart,

fast and cost-effective process. It eliminates costly and bulky VGA cabling, allowing VGA monitors
to be connected at a distance from the PC via standard shielded twisted pair cable.

Application Tips:

Must use STP RJ-45 connector (shielding – metal housing). The correct cable connection is as follows:

1. STP (shielding twisted pair) Cable

2. STP (shielding) RJ45 connector
with STP cable connection.

If your RJ-45 connector is plastic housing (unshielded), then the cable connection must be as follows:

1. The ground cable must pull out
around 5-10cm length to connect
with VGA BALUN’s D-SUB screw
for grounding.
