New install using a Royal and 100% PBUS. In the Output mapping menu I mapped channels to ports in sequence. For example, channel 1=port a, channel 2=port b, channel 3=port c, etc... All seems to be working perfectly. My doubt is based on the mapping between physical ports which correspond to BUS A and BUS B and the 2 physical PBUS ports which also correspond to BUS A and BUS B. Some of my BUS A ports like L or M, N are physically connected to PBUS port B although on the unit they're part of BUS A.
Does the output port mapping matter when only using the PBUS ports? Or is it dynamic based on the SBUS channel being recognized on the physical PBUS port? It doesn't seem to, and you only have 6 BUS B output ports to use, so it's impossible to evenly map/split channels between the two buses one for one. I tried and was unable to map them as I have more than 6 SBUS channels connected to the BUS B PBUS port. I hope my question makes sense, it's late here. LMK.
