I'd like to use a pc for the controller instead of the Ocelot. Is it possible to get the specs on the ADnet Protocol?

I'm an SysAdmin/Programmer. I'd like to set up a single PC with multiple RS485 cards that can monitor multiple ADNet networks throughout our building. This would be a custom in-house design, not to be used externally.

I currently have two networks in production, each equipped with a PC/Ocelot for monitoring. The objective is to use one PC and multiple RS485 cards to monitor the entire building.
