E1.37-5 URL parameters - E1.20 RDM (Remote Device Management) Protocol Forums

sblair · January 31st, 2021

Jim,

E1.37-5 is getting ready to go back out to Public Review in the next couple months. Interesting suggestion on the HELP PID. I'm hoping that the Parameter Description JSON functionality will reduce the need for that by being able to completely describe PID functionality. We also have a JSON URL PID that allows a device to provide a URL where the machine readable JSON description can be fetched as well that should provide similar functionality as to what you've described.

Thanks for the quick reply!

The JSON PID sounds ideal for flexibility.

I've been concerned that I don't have a ton of space in flash on our small devices to store long static JSON scripts. I certainly wouldn't do it as straight ASCII, more likely I'd devise a system of symbols to represent keywords in a lookup table. It's considerable infrastructure to build, in any case.

A URL to an online JSON script is a good solution. I look forward to these things becoming part of the spec, and then -- of course -- for controllers to implement them, grabbing those JSON scripts and storing them locally for when the cord is cut while running a live show.

Thanks again,
Jim
