Unless I am mistaken, to add a power sense condition to the action list, an extender needs to be enable for the device. This means that IR will go through the extender and IR emitter needs to connected to an IR port and attached to the device (or an IR cable needs to be used).

An alternative would be to use ProntoScript to test the power sense condition and built the conditional logic required. In this case, an exterder does not need to be enabled for the device.

Is my understanding correct?

PS2,

For true power sensing you'll need to use the RFX9600 with some sort of physical connection to the controlled device that the RFX can work with. (a level sense or RS-232 communication) An RFX9600 input level sense can used without ProntoScript. RS-232 needs ProntoScript.

You could attempt to use ProntoScript and a flag, but this technique will fail if a human directly changes the power status using the unit's remote or front panel.

XANTECH offers a few little accessories that can provide input to the RFX9600 based on various input signals (such as video ON/OFF, and current sense).

Some programmers use power toggles, then throw up a screen asking the operator "Has the unit really turned ON? If not, try using this power button again." To me, this does not inspire confidence. It suggests that the remote is not really in control of things.

You are correct.

With PS, you can access any extender and port you want. However, note that the Extender "still" applies for any IR codes that are sent. The Activity where the code is located (PEPv1) will control how IR is output.

For the hobbyists out there and people with some elctronics background or who can program reasonable RS232 protocols:

There is a company called weederTech. They make little IO boards that have a simple RS232 interface. They daisy chain together and use only one RS232 port managing the communications buss so there are no collisions.

One of the boards is a general purpose Digital input board that can be used to sense 12 contact closures. Another one can be used to sense a voltage (I think 4) (like a little DC wall wart puts out or many AV components put out to control screen relays etc. Another one handles 4 solid state relays. I use them a lot for Home Automation. They are small efficient and could do a lot of little things such as whar=t is being discussed here.

Hello,

Just a little line to say that I use different Sensors from Xantech ( Power, Audio, Video and Magnetical field ) and they all do great job. The connection to the RFX9600 is very easy. All the Power sensing modules work perfectly, but you need to take care : when you by a module, don't forget the connecting block.
