A some may recall, I was recently trying to devise a quick way to assess the power state of my Pioneer displays using 2-way RS-232. Well, I've FINALLY discovered a query command that generates a response which includes power state info. (It wasn't in the RS-232 documentation.)

It's a 39-byte response that includes data about the panel's current state, with the forth character (the first actual variable) indicating power state. Other variables, like the hour meter data, will change with each iteration of the command.

I'm wondering if there's any way I can use this response short of using a widget filter. FOr example, is there some way that Nevo could truncate the response, ignore subsequent characters, or otherwise filter for that fourth byte for an IF/THEN/ELSE command? It seems like that would be a very quick & efficient way to use the info.

Most likley yes.

Can you post the data?

But this can only be done with widgets.

if/then will ONLY work if the data has an EXACT match. Widgets can check against the 4th character.

Sure. The query command is QS2, and here's an example of a response:

QS2P0000-**267000***0014594200000****45

The 4th character reflects the power state and has three possible responses. The two relevant ones are P=ON and 1=STANDBY. The subsequent characters indicate other operational conditions.

I was afraid IF/THEN/ELSE would only work with exact responses. That's the only way I've ever known how to use it. :(

Here is a widget to try:

Pioneer Power State.

You will need to delete my RS-232 device and replace it with yours, I left it there so you know how to join it up.

Also.
I am not sure if QS2 is all that is needed to trigger a request. You may need a \r or \r\l etc...

But using the Nevo de-bugger software it is working as expected.

Thank you! I'll give it a try first chance I get tomorrow. :) I'll let you know how it works. Thanks much for taking the time...

(The Pioneer protocol does use start and stop bytes, but for simplicity, I didn't include those.)

No prob.

That widget may not work if there is extra data in the reply string. Its 50/50.

If it doesn't can you show the full data and I will change the filter to suite.

After initially going through and customizing to my own equipment, I'm finally getting a chance to try this out. Now, assuming I get it to work and successfully set the global flag, does the widget need to be added to every page that includes commands that might check the flag's status?

Hi,

Yes and no....

The "global" flag can be checked without the widget on the page but the flag will only be updated by the widget when it is run. It will only run when it is on a loaded page.
