Missing RDM pararameters - E1.20 RDM (Remote Device Management) Protocol Forums

For fans, I think SENS_ANGULAR_VELOCITY is a better choice than SENS_FREQUENCY.

I do understand the point that you are raising. It would be nice to have the commonly used units like RPM and Percentage available directly in RDM. The problem you run into is that there are an unlimited number of unit combinations.

Lets use fluid flow rates as an example (which could be applied to fans and fog machines), offhand I can think of at least 8 units that are commonly used:

Gallons/Hour, Gallons/Min, Cubic Feet/Min, CC/Sec, Cubic Meters/Sec, Liters/Minute, Barrels/Day, Gallons/Day.

Which of these should the standard support? You'll never find a superset of units that will please everyone.

By sticking strictly to MKS SI units the standard ensures that there is a simple, well-defined set of units that everyone can understand. There is one unit for everything. A controller can offer a right-click menu with the option to convert to arbitrary units if desired.

I want a unit for furlongs/fortnight!

furlongs/fortnight, wow!

you're right, there would be unlimited possibilities. My intention was to raise some attention to this matter, and I think we got there. And,as you put it, [rpm] and [%, 0/00 and ppm] may be of some importance within our industry.

For Vegas, we thought of preparing a RDM-controlled slot machine (before Doug does it). This will fail, because UNITS_CURRENCY does not exist. Together with the LANGUAGE option, displaying EUR, GBP or USD might have been possible. Now we might quit this project

All for now.
best, e.

Fan speed is something I've just implemented... and by looking for ' RPM ' in the description. You'd never guess it wasn't in the standard!
