## Questions & Answers

**Q: How long are the power cables from the adapter to the plug?**
A: About 4 feet and they can be powered from either end.

**Q: Could you theoreticaly use a router to create more outputs? Has anybody tried it?**
A: Common misconception. Routers and switches use Ethernet. Ethernet is a layer-2 protocol. Ethernet is not about the cable, but about the software.
These boxes use Cat5/Cat6. Those are physical cables, not protocols. These do not use Ethernet, and therefore cannot be routed or switched.
To sum up:
Routers and switches use Ethernet > These VGA extenders don't use Ethernet > Therefore, you cannot send this signal through routers or switches.

**Q: compatible with gefen?**
A: We are unable to confirm exactly which device you are referencing. The ST121UTPEP will work with any direct VGA source and VGA display. A loss of video signal and quality are common symptoms when video adapters and extenders are used in conjunction with each other. 

Atha, StarTech.com Support

**Q: Do you offer just the receivers for sale? One cat6 into a ip switch, have three receivers. Will that work?v**
A: See my review. It only has 1 (ONE) Ethernet (Cat5/Cat6) output, so only 1 receiver is possible. https://www.amazon.com/review/R3R714AWMSCZNC/
