Sensor type and Sensor unit for DMX rate question
 
Hello,

Which are the correct sensor type and sensor unit definition to use for measuring DMX frames / second?
SENS_COUNTER_16BIT ?


I see no UNIT_ events / second or counts per second etc. UNITS_HERTZ might work but doesn't sound right somehow?

Kind regards
Bernt

SENS_FREQUENCY and UNITS_HERTZ seem the most appropriate to me.

Counts per second is the definition of Hertz.

Strictly speaking it is defined as 'cycles per second'. That is why I thought it is not 100% correct for 'frames per second' or 'counts per second'.:)

It is probably the most appropriate one in the list, as you said.

I would say that Hertz (1 Hz = 1/s) would be the appropriate unit to use for this. [Hz] is the most commonly used unit for measuring periodic events even in cases when it is not "pure" cycles. But I suppose that one can also argue that a DMX frame could be describes as cycles... Break->MAB->SC->Data->MBB->Break->MAB->etc.... So if you'd like I suppose you can see the DMX refresh rate as the frequency at which the NSC arrives.
