8.2 General Questions About the Micro Extender

Is it possible to use an interconnection cable longer than 50 meters (160 feet)?

The standard-from-the-factory Micro Extender has been designed to produce acceptable results with SVGA resolutions at the maximum cable length of 50 m (160 ft.). You can try running cable farther, but not very far beyond 50 m the video quality begins to degrade rapidly. If you need to run longer distances, please contact Black Box Technical Support; they might be able to suggest more powerful alternative equipment.

Can Micro Extender Units be daisychained to allow operation across a distance greater than 50 meters (160 feet)?

We do not recommend doing this, because the Micro Extenders’ video equalization can’t be fine-tuned and can easily break down over the length of a daisychain.

Can the Micro Extender be used between buildings?

No. Ground loops could destroy the Extender and attached equipment.

Can I rackmount the Micro Extender?

The Micro Extender is designed for desktop use. You could set it on a rack shelf, but there are not currently any rackmount or wallmount kits available for it.

Is the Micro Extender VESA DDC compatible?

No. It cannot carry the special DDC data lines.

Can the Micro Extender be used with RGB video?

As long as the video has sync on green (the composite sync signal superimposed on the green color signal), there should be no problem.

Which cable type is better: UTP (unshielded twisted-pair) or STP (shielded twisted pair)? In electrically quiet environments, UTP cable will give the best quality video over long distances because it has less capacitance per unit length. However, STP is usually better in electrically noisy environments, because it resists interference more strongly.
