The Master Control Unit (MCU) is required on larger systems consisting with 3 or more Circuit Control Modules (CCM’s). The MCU is the central processor that drives the entire system, power, intelligence and decision making talking to the other system components via the NMEA2000 network.
There is a range of different MCU’s available, the MCU-200 and MCU-250 have the added advantage of GSM connectivity which allows the owner remote control of the system as well as TXT notifications in the event of system alarms.
Due to EBay's brilliant idea to run our business's as though it was theirs and yet take no responsibility; We have to list all of our items as remanufactured or used. We strive for customer service as we have here for over 20 years. That said, trying to provide quality products, fast shipping, great customer service and the lowest price while paying return shipping, and waiting up to 2 1/2 months to get our product back is not possible in sustaining our business. We hope you understand. We Pack Well and Ship Fast!!! Thanks for looking, Jeff
