If you'd like to connect your computer to a remotely located monitor, check out the Niles C5-VGAWM. This clever device uses durable, shielded CAT-5 cable to send VGA video signals to another room in your house or office. It installs neatly in your wall for a décor-friendly look and delivers crisp, detailed video, even over cable runs of up to 330 feet.

How it works
You'll need to purchase two VGA baluns to set up a fully functioning system. You can use two C5-VGAWMs, or pair one with a small component-style model. Installation is straightforward — just connect them both to in-wall shielded CAT-5 cable, then mount them into your wall. Place one in your main room, and connect a computer or other VGA video source. Install the other in your remote room. Then hook it up to a monitor or projector via its VGA jack.

What is a balun?
A balun gets its name by converting signals between balanced and unbalanced lines. Balanced cables can carry signals over much larger distances than unbalanced lines, because of their superior noise rejection. The C5-VGAWM balun converts video signals between balanced CAT-5 connections and unbalanced VGA video connections.

Product Research



Product Overview: The C5-VGAWM is a transformer (Balun) to convert a CAT-5 signal to VGA video, and vice versa. Typically two are used at opposite ends of the signal path; one unit converts the video source to CAT-5 for transmission over a long distance, a second unit converts the CAT-5 signal back to VGA to feed a monitor.

Mounting: The Balun is designed to fit into a single gang J-box using the included wall plate. Multiple insert plates can be mounted in larger J-boxes using Decora-style wall plates designed to cover multiple gang J-boxes.


VGA: The female DB-15HD connector (D-sub15) on the front of the C5-VGAWM can be used as an input and converted to CAT-5, or as an output to feed a monitor.

CAT-5: The RJ-45 jack on the back of the unit can be used as an input and converted to VGA, or as an output to feed the network.
