UMC-1 USB MeterBus Adapter
The USB MeterBus Adapter (model: UMC-1) converts the Morningstar MeterBus RJ- 11 electrical interface to a standard USB 2.0 interface which allows communication between a PC and applicable Morningstar charge controllers or inverters *. The UMC-1 is required for programming custom charging set-points and logging data using Morningstar’s MSView PC software. The UMC-1 is also required for rd communication with any 3 party hardware that supports MODBUS™ communication.
- Morningstar controllers or inverters that only have a MeterBus connection , i.e. no serial or other communications port. This includes the Sunsaver MPPT, SunSaver DUO, and Suresine products.
