AI Sol Data Cables & Neptune VDM

[Enigma]

I originally thought that each of my two AI Sols would need to be plugged into a VDM to control them.

Now, I'm wondering if the Sols can be connected to each other with one of the supplied data cables, and then one of them wired into a VDM. Should this work to control both units identically with one Neptune VDM? I have all of the required hardware and cables to install them this way.

I checked the AI site, but can't find any documentation. The included "Quick Start" guide is very simple and doesn't cover this possibility: if it is possible.
