The PiCap is outputting DMX on pins 1 and 2 when using the DMX jumper settings on the PiCap.

OK, that's how I have it all wired.  But I would think it should not be sending any data when all outputs are de-activated and no sequence or test mode is running in FPP, correct?  I cannot figure out why the PiCap sends a chase across channels 1-3, and channel 4 at full inherently.  Should I address my fixture higher?  My sequence will only be using DMX and no other protocol.

There are some DMX fixtures that require the third wire - "ground".  (I have some that do, and some that do not.  Go figure.)  If I remember correctly, that is pin 7 and/or 8 in the RJ45.  It is pin 1 in the XLR.  For those same fixtures, without that ground, strange behavior is seen.  Pehaps this is what you are seeing.
Sequencers: Vixen3 and xLights
Players: FPP and xSchedule Controllers:  Renards - SS24/SS16; E1.31 - San Devices E682 - Falcon F16, F4, F48 - J1Sys - DIYLEDExpress E1.31 Bridges.  Much more!

That was it!  I had tried pin 3 and pin 6 on the RJ45 based on some other pin out diagrams, but it turned out to be 8.  Thanks!  DMX can be so finicky...

Do you have any video of this light running?  I have been wanting to put a few of these on the house
