VGA & Component Video-over-CAT5 Extensionss

4. Troubleshooting

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

If you have a stable image but it looks somewhat blurry (object or character edges are not sharp), try to adjust the compensation first. When the trim-pot is turned fully CCW there is no compensation. As you turn the pot clockwise you are applying compensation. Look at the screen and slowly turn the pot clockwise. Notice what happens to the right of solid horizontal lines (as in figure 3.1). If you still have a fuzzy image, try reducing first the refresh rate and then the resolution of the PC.

2.Shaking image or periodically blanking monitor

CAT5 cable employs twisted pairs to differentially transmit the signals from the transmitter to the receiver in order to reduce the amount of EMI (interference) coupled noise from external sources. However, 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. Note that separating the CAT5 cable from the EMI source by a few inches is often sufficient to eliminate this problem.

3.The PC does not recognize a Plug-and-Play monitor

If the PC’s Operating System is setup to detect a plug-and-play monitor (usually in Display Properties Advanced Settings), it may have trouble finding a monitor. If the PC does not produce an image due to this, disable the plug-and-play monitor detection in the PC’s operating system Display Properties.

4.Substituting power supplies

The sender and receiver rely on the power adapter that is supplied with them. Do not substitute any other power supply or DC power source
