G3-Mp3 director problems

[olracs]

I have two pixel one systems from Sandevices and two Elors so I can run it through my G3-mp3 director. I cannot get it to connect to network #2. And it will not connect network #1 using 500K.

In sequence editor, Rgb channels is set 4A through 4D  network set to AUX A

In preferences, Aux A is set as , comm none, 500k

Hardware utility, checked MP3 box, checked 500k network 2

 

 

Network one works at 115.4K and slower, not connecting in network 2

Is there something I'm missing

I've tried other thoughts like trying to change the comm in Elor, it wouldn't except a different comm, only to disconnect.

I'm at a lost.
