Omnilogic and VS900 & VS950 Pumps

I recently installed the Omnilogic Base and was able to connect the Hayward VS950 pump to the system and configure it properly under the Pool Body of Water (operates 24/7). However I have a second pump (Hayward VS900) that also runs the Pool Body of Water (10a-10p). The second pump is for the DE Filter.

Note that I do have a second Body of Water (Spa) that will require both pumps to shut off so the actuator valves can turn and then only the VS950 will operate the Spa while the VS900 will have to remain off.

Can you connect a second pump to the Omnilogic Base to operate under the same Pool Body of Water? If so, how is this achieved? I have the communication cable but not sure where on the Omnilogic Base this would connect to or how to program.

Any insight on how this achieved would be great! Hayward support is a waste of time and only points you to manuals and their FAQ’s Site. Quite frankly, both of these are useless as well.
