Mini Cat5 VGA Transmitter w/ Local Port

3.Troubleshooting

1.Fuzzy, blurry, or ghosting image at remote location

If you have a stable image but it looks blurry (object or character edges are smearing), adjust the compensation on the receiver. If you still have a fuzzy image, try reducing the refresh rate and/or the resolution setting of the video. For Best results use either low-skew cable (such as Belden Brilliance® VideoTwist), or Cat5 (instead of Cat6).

2.Shaking image or periodically blanking monitor

A strong electromagnetic noise field can cause instability in the signal. Usual sources of this form of noise coupling are high current AC lines or other high-density data and/or control cables that run adjacent to and parallel with a substantial length of the CAT5 cable.

To eliminate this, either separate the Cat 5 cable of Mini-CAT5 Extender from the interfering source or use shielded CAT5 cables. Usually separating the CAT5 cable from the interfering source by a few inches is sufficient to eliminate this problem.

If the length of Cat5 run exceeds 300 feet you may need an additional power supply at the receiver.
