ArcSystem D1

Hello. We had a series of the ArcSystems infrastructure put into our house for General house lighting. I was not around when they did the install. But needing to replace a few of the drivers. I cannot figure out or seeing the instructions for the life of me where and how we would assign or address DMX channels. I do use satellite for all of our Multiverse NFC items and I do see the Arcsystems listed. I'm wondering what the way of connecting to the drivers would be? Any help that anyone would have would be fantastic. Thank you. Preston
