Not exactly what the thread is about, but when I installed my Roland printer I wanted it on the other side of the room from my computer so I needed to run a 50' CAT5 cable in the wall behind the computer, up over the ceiling and down the other wall (didn't want the cable on the floor).
I also wanted to install wall jacks, so it would be easy to move equipment if needed, I installed the two standard CAT5 wall jacks into the walls and used the 50' CAT5 cable to run between the two wall jacks (in the walls and ceiling). A standard short CAT5 cable from the printer to the wall jack, and on the other end from computer to the wall jack, I had to use a short CROSSOVER CAT5 cable.
It's been working fine for years now, and I have been told (by the electronics store guy) that I could run the CAT5 cable between the jacks 100's of feet if I needed to!
Just thought someone new might benefit from this info.....
