Post SLOT_INFO with Secondary Slots

Hello,


I'm developing a tool that deals with responder Slots, and am trying to understand the boundaries of what the Standard allows with regards to SLOT_INFO and 16-bit parameters/functions.


The standard states that a responder has 16-bit parameter(s) when it has both a Primary (ST_PRIMARY) and Secondary (ST_SEC_FINE) slot(s). The type of slot is discovered using SLOT_INFO.


Secondary slots are meant to report the Slot Offset for the Primary Slot they refer to, however as far as I can tell there are no rules in the standard preventing a responder implementation from having multiple Secondary Slots pointing to the same Primary.



It seems to be legal, but I can't see why a responder would have multiple Secondary slots for the same Primary, so was hoping someone could provide a use case for one? Or point me towards where it states that is forbidden?



Thanks,
Rory

Rory,

Welcome to the RDM forums!

Yes, you can definitely have multiple secondary slots pointing to the same primary. It can be quite common on moving lights with gobo wheels and color systems too. There is a good webinar we did on this subject a couple years ago you can find here that I think will hopefully provide a lot of insight and some examples of this.

Hi Scott, little while no speak!


Could you share a couple of practical examples of a real product that implements RDM defined slots in this way? I'm curious.


I foresee that the permutations and combinations alluded to, or allowed by the standard are as robust as two marrows connected by a cucumber on a hot day!



Best

As an example, it's very common to have "Pan Coarse" as Primary, and to have secondaries for "Pan Fine" and "Speed" on a moving head.

More confused.
Do you mean "secondaries for" or "secondaries of"?

Here's an example from the roundtable presentation Scott posted earlier:

Here's a common example from a moving light for the Slot Info data. This was from a High End Systems fixture.
Code:
                    // Pan High
                    ParamData[i++]             = 0x00;                    // Slot Offset 16-bit  High
                    ParamData[i++]             = 0x00;                    //   "     "        Low
                    ParamData[i++]             = ST_PRIMARY;              // Slot Type 8 bit
                    ParamData[i++]             = SD_PAN >> 8;             // Slot Label ID 16-bit. High
                    ParamData[i++]             = (BYTE)SD_PAN;            //   "     "   "         Low
                    // Pan Low
                    ParamData[i++]             = 0x00;                    // Slot Offset 16-bit  High
                    ParamData[i++]             = 0x01;                    //   "     "        Low
                    ParamData[i++]             = ST_SEC_FINE;             // Slot Type 8 bit
                    ParamData[i++]             = 0x00;

                    ParamData[i++]             = 0x00;                   // Slot Offset 16-bit  High
                    ParamData[i++]             = 0x02;                    //   "     "        Low
