Hi there!

While I'm still waiting for my new Q50 to arrive, I have some technical questions about the video and power sensors.
I know that they are to be connected on the NevoConnect module, but what about the other end? Where do you actually connect the sensors on your devices like the amp or your dvd player, tv set, ..???

Cheers,
HighDee

HighDee,

Depending on your devices (some will have a 12v trigger, some will have a switched AC outlet).

The Nevo Voltage Sensor provides a 2 pin connector to use for attaching a wire between the sensor and the device trigger output. It also has an IR output port so you can sense the power state of your device and send IR signals to it through the sensor.

If your device doesn't have a 12v trigger but has a AC outlet, then you can use a 12v AC adaptor (if it has a 3.5mm mini plug on the end you can just cut it off so that you have bare wire to be able to plug into the Sensor).

So from the back of the Connect, you plug the 3.5mm jack from the Sensor into one of the IR ports, you then plug your IR emitter into the 3.5mm jack that is on the sensor. You would then choose the triggerd output on your device to wire into the 2-pin connector of the Sensor, or the AC outlet.


Many devices as you know have the trigger output and it is set high when the device turns on. The Voltage Sensor detects this signal and provides a trigger voltage used by the Connect to determine the power state of the device. The power command can either be sent or not, and your macros and equipment remain synced.

The power to the Sensor is provided by the Connect so you don't need any additional power supply.

Once you tell the Connect which port is to be used and that it is a sensing device, you are good to go!

Hope this helps, and I hope it's not too long winded.

Mike

Mike, thanks a lot for your very detailed answer! But I still don't know what to do when there's neither a AC outlet nor a 12v trigger! Are the sensors of any use for me then?

If there is no trigger or AC outlet then the power Sensor is not going to work.

What deivces are do you have and what are you looking to do?

I have a DVD, receiver, TV and cable box.

I leave my receiver and PVR on 24/7, but with my DVD I use the video Sensor because it does't have a discrete power on/off. That way when I hit my all off button on the remote, it won't turn on or off depending on it's status.

Well, I have a multichannel pre amp, a stereo pre amp, some amps, a ps3, an VP50pro scaler, a beamer (RS1), a motorized screen wall, an HD-DVD player and an HTPC. And I want all of these babies to be remote controlled by macro execution... I have a "pronto pro" by Philips to do that job right now, but I was hoping for these Q50 sensors to do that job even better.

Welll,

My understanding is that the Sensors will only allow control over the power (except the serial sensor).

Depending on what macro's you want the Q50 do, the sensors will only stop the devices from turning on or off when you do/don't want them to.

It works well for me because when I am watching TV or listening to digital music on the PVR my DVD is off. If I didn't have the video sensor or power sensor then my DVD would turn on when everything else turns off.

Another great thing you can do with sensors is to skip large delays for TVs.

You see, usually when you program your macros, you put in a really long delay which gives your TV enough warm-up time to switch inputs. But if the TV is already on, there is no reason to have this delay.

I used a video sensor on the "video out" on my TV. Here is how my IF/THEN statement looks:

If Nevo video sensor
Then
Send TV
Delay 6500ms
Else

As you can see, with an IF/THEN statement like this, if the device is sensed Off, the power command and delay are executed (in my case, when the TV is off, it no longer sends a signal through the video out port and thus the Nevo video sensor knows that the TV is off). But, if the device is sensed On, then these commands are passed up.

This really helps for when someone is going from one activity to another. Meaning, if you hit your "Watch DVD" macro and after the movie finishes, you hit your "Watch Satellite" macro, you won't have to wait 6.5 seconds because if the TV is sensed on, the delay is skipped. This makes for a very seamless macro experience.

Hey, sounds pretty cool! So maybe this remote is still good for me even without the benefit of these power sensors. Very nice!

Oops, I didn't realize that when you use the "greater than" or "lesser than" symbols in this forum, the contents between them are ignored and thus my If/Then statement appeared incomplete to you guys. I typed it out exactly how it appeared in NevoStudio Pro and they use those symbols.

Anyhow, here is what the If/Then statement should have really looked like (I just took out the symbols):

If Power Off Nevo video sensor
Then
Send Power On TV
Delay 6500ms
Else

I hope I didn't confuse the first time around. I'm glad you guys like the idea, although I can't take all the credit for it because I heard it while going through Nevo training. :-)

Any recommendation for 'Power Sensors' ?

Need to sue sucha device on my satellite system as only have 'toggle' on/off and no power status output.

How about the video sensors? How do they work?
I have a Vizio plasma tv without descrete on/off codes and need to control it.
Does the Plasma need to have a video out for this type of sensor to work?

Just received my video sensors and having trouble getting them to work properly. I have a Panasonic SA HT900 HTiB that i am using for my audio which doesnt have a discrete on/off code which is what led me to by the video sensor. I placed the sensor on the video out of the HT900 and setup the if/then statement in my power macros however no matter what i do it always says its on?

Here is my Power On macro:

If Nevo Video Sensor
Then
Send Panasonic Audio
Else


Power Off:

If Nevo Video Sensor
Then
Send Panasonic Audio
Else

I thought it might have been that my HT900 wasn’t sending out a signal so i tried my tv with the same results. Always evaluates to sending the power on state. Any ideas?

Update: Just figured out that the problem is that my POS HT900 only outputs video when playing a DVD which i guess makes sense although seeing as the video sensor doesnt work and as mentioned above it also has neither an switched ac outlet or 12v trigger so i can't use a voltage sensor i might be SOL. It does have FM & AM outlets for each antenna. Dont suppose there is any chance i could use one of those with a voltage sensor :) ?

If not it seems that the only way to figure if this HT900 is off/on would be with one of these

although it cost almost as much as the whole HTiB. Anything cheaper out there?

thx

Take a look at one of these voltage sensors from Xantech:

[Link: xantech.com]
They have another module, the CSM1 that uses a regular plug input/output, too.

I'm currently looking at one of these for my TV but it appears they might work for any piece of equipment. And, someone earlier reported that they do work with the NC-50.
