CMM366B-4G/CMM366CAN-4G Cloud Monitoring Communication Module is 4G wireless network communication protocol switching module of global network communication, which can achieve genset (with SCI) connection with Internet. After logging into cloud server, module will receive corresponding genset controller communication protocol from cloud server. Cloud server module can obtain genset data information via RS485, USB, LINK, CAN, or RS232, and send the information to related could server via 4G wireless network. Users can at real time monitor genset running status and check genset running records by mobile APP (IOS or Android), or PC etc. terminal device. 
It not only can realize genset monitoring, but also can be connected with some digital alarm inputs, to realize monitoring of genset entrance guard, prevention of burglary, fire control etc. ancillary facilities. 
It has GPS positioning function, which can upload the obtained longitude and latitude, altitude information at real time to the corresponding cloud server. 
CMM366CAN-4G cloud monitoring communication module has CAN port, but CMM366B-4G hasn't. Except for this, these two cloud monitoring communication modules has same functions.
