Fulltimer,
Yes, if your coach is wired per the diagram (called audio.pdf) in a post at this link, then connect the cable with the green tape to the SAT IN on the satellite receiver. Then, out in the UDC, connect your satellite dish to the Sat. jack on the right, towards the rear of the coach.
Be patient as you do all of this and plan a fair amount of time for it. A few coaches have had the 2 wires mis-labled and a few coaches have had a defective cable and/or connectors coming from the UDC into the entertainment center. The first time doing this, I'd suggest you use a portable TV set with the satellite receiver outside of the coach and peak in your dish first. When you have a great signal level and picture, secure the dish, connect the wire from the dish to the rear jack in the UDC, move the receiver into the entertainment center, conect the green labeled wire to SAT IN, power it up, then connect your TV set in whatever manner you choose (TV OUT or VIDEO OUT).
Should work. If not, post your issue in the Satellite section of this forum and we'll give you some ideas.
The blue labled wire goes from the entertaiment center to the VCR input on the RF Switcher in the coat closet. This will allow you to connect any audio/video source within the entertainment center and route that source to your bedroom TV and basement TV jacks. Note that your audio/video source must have an RF (TV) output as this is a single RF cable running to an RF only switcher.
Another option is to install an inexpensive external RF Modulator on the video/audio outputs of an additional audio/video source (DVD/VCR/iPod etc), tune it to channel 3 or 4 and connect the RF output to the blue cable. See more information on this in the Entertainment section of this forum.
Best of luck to you,
Jim
