I'm trying to install and configure a station module on a Norstar MICS system. I've already attached the station module. The power, fiber, and 66-block are all connected and powered up. Under Hardware I've assigned Station Module to module 12. Under Maintenance I've made sure Module 12 is enabled. However, under Maintenance Mod 12 says empty and if I check the state is says unequipped. What else do I need to do to make a station module work? Thanks for any advice.
