UPDATE: no longer an issue. There was a random "unknown" module attached, but there was none. Once I deleted it, I was able to access the new DOS.

Just installed a new Neptune DOS. It's daisy chained via aquabus to my other DOS. The lights on this new one show green, not orange, and I don't see it in my Fusion Dashboard nor the browser connected to the Apex Jr.

My Apex Jr. now has 7 modules attached:
1. ATK (FMM)
2. Another FMM
3. Auto Feeder
4. EB4
5. VDM
6. DOS
7. DOS (the new one)

I attached the display module to the last and new DOS, and it lights up and shows the Apex Jr. controls. But I don't see that new DOS.

When I try to press the manual rotation, nothing happens.

I have the power source plugged in. The aquabus connection is made using the supplied aquabus cable.
