Howdy all,

I am still confused after reading everything about making a query with PS on device status using RS-232.

If someone could write up an example that starts me down the path of a clue it would be greatly appreciated.

Here is what I want to do. Everything is RS-232.

I have a home screen that I access via the home button and I am already watching DVR1 and want to watch DVR2. Normally the script would have to go through all the motions not knowing the Receiver is already on and has to go thru all the delays the macro must do when it switches. I would like to tie a PS so that whenever I press DVR1, DVR2, etc it will poll the receiver on the status of power and even the status of the input it is on before running thru the macro. This was so much easier on the MSC-400. LOL

Any advice?

Thanks in advance.

Cheers!


Edit: I do not want to do Device Tracking since I have the ability to make a status query.

Sure helps if you tell us the type of receiver or include link to PDF with protocol so we have some idea of the capabilities.

Your fav Lyndel, Denon Serial.

I just want to use the PW? and the SI? query command. Once I see how to do it I will figure out any other queries for other devices.

I also want the button to double as a working button, not something hiding on a page.

Thanks!

If doing this using syncrhonous serial port...

Set following parameters programmatically.

9600, No parity, 8 data bits, and if you can, 1 stop bit.

var pwrResponse = mySerial.match('PW?\r','\r',2000);
var siResponse = mySerial.match('SI?\r','\r',2000);

Note that responses will have '\r' at the end and you will have to trim them.

FYI, the examples in the dev guide specifically do 'MVUP\r' or 'MVDOWN\r' and were written for denon receiver. Please have a read through the dev guide and try out the examples.

Now, on to using this as macro. Add any actions you want to a button. Click the 'PS' icon on the toolbar to enable ProntoScript for the button.

//===========================================
// This code will execute the current button's actions if power is off.
//===========================================
// TODO - Put code in to retrieve current extender and target serial port.
// You can see dev guide for example on how to do this.

var pwrResponse = mySerial.match('PW?\r','\r',2000);
if (pwrResponse.substring(0,5) === 'PWOFF')
{
// try/catch extra bulletproofing if jump action is present.
// Search this forum for ActionList Error.
try{this.executeActions();}catch(e){};
}

FYI, Prontoscript can ONLY be activated from visible buttons on a page. It can also be executed upon entry into an activity or into a page.

I understand your eagerness to experience these new powers but you will save yourself lots of grief and headaches as well as time posting many questions if you create small configurations and test through the examples as best you can in the Dev Guide.

Please don't take this the wrong way. I am not trying to beat you down, but rather, build you up and make you more productive in the Pronto Javascript world.

I would if I could. I am good with alot of things but when it comes to scripting, God did not allow me the ability to create something new but just modify something done.

Thanks for the tip. It is all I wanted as a starting point to modify. I use RS-232 on all my installs. I just have issues with javascript.

Thanks again for the help.


...and I respect your advice as well.

Good luck.
