As requested, here are some pictures.
An RF-IR remote system contains several components. First, is the actual RF remote control. The RF remote communicates with the RF extender seen here:
This RF extender is hidden in a cabinet and out of sight. It has a power cord to keep it turned on, as well as several ports in the back for IR emitters. Each cord typically has 2-3 emitters on it, so you can hook up several pieces of equipment.
The next step is to plug in an extender and work the cable through your cabinet to the piece of equipment you wish to control. Keep in mind that RF and IR do not talk to one another, so the sole purpose of the extender is convert the RF signal to IR (line of sight). You must locate the IR sensor on each piece of equipment you own. This can typically be found in the owner's manual, or by shining a flashlight across the front panel and looking for the sensor there. Once located, you simply attach the end of the emitter to that location as I've done on my receiver below:
The plastic square around the emitter allows it to stick to the equipment, while also blocking any external light so that it's a very secure transmission. Repeat this step for each piece of equipment.
You may have to run emitters to equipment that is visible. In most situations, your TV will be the only thing that applies. Follow the same steps and route the cable up through your cabinet and to the sensor on the TV. Again, here's a quick pic of mine:
Once the remote is programmed to include all of your equipment, you can now simply press the button marked "watch TV" and everything will turn on as it should. Close the cabinet doors and the problem is solved.
Keep in mind that the only visible cable at this point is the one connected to the television. If that bothers you, you can always omit this step and simpy point your remote at the television directly to turn it on via IR. All of the equipment in your cabinet will still work over RF. The benefit of having the television added to this scheme is that you can turn everything on (tv included) from pretty much anywhere.
Hope that helps!
