I suggest you check out the RS232 manual from the Lumagen website. It lists exactly what feedback can be queried - it is A LOT - and yes, what you are looking for is already available. (And just in case something would be missing, I could very well envision that the Lumagen team would add it shortly, judging from their excellent customer focus and support.)
I have fairly easy access to the RS232 port, so I can switch connections easily.
Thanks Axel. Just checking the RS232 manual.. One question, does Irule auto "decrypt" the feedback and display on-screen? i.e. do I need to program anything to decode the feedback?
I assume you are already familiar how iRule's feedback feature works. If not, suggestion is you check out the Tutorials on their website.
Unless you can find the feedback"file" for your device already in their database, you will either have to 'roll your own' or expand an existing one. There you can do the mapping that will be needed if you want to show something different in the iRule app. than what the device sends, let's say instead of "1" or "0" you want "on" or "standby". I have shared the one I made under 'Lumagen Mini-3D'. You could use this as a basis and add the addl. feedbacks you wanted for CMS, AR, etc.
