CNV580 - Modem IIoT

CNV580 is the Pixsys IIoT Modem for remote data monitoring: an all-in-one solution including modem, SIM card, Cloud service, PixsysGuard App as user interface. No additional contracts with service providers are required.  The data traffic pre-loaded on the SIM is estimated to last at least 5 years (depending on the data volume used by the application).

The dimensions of the CNV580 are compact and the functionality is optimised for either stand-alone use or networking via RS485 serial. In the first case, with digital I/Os or via the 4...20mA analogue input, it is possible to collect data from sensors or other devices. In the second case the RS485 serial via Modbus RTU protocol connects the CNV580 with other Pixsys devices equipped with serial and allows reading/writing of selected variables. In both cases push notifications on App for alarms, power status or other events are enabled. 

Installation, activation and control are simple and immediate thanks to the Pixsys Guard App with preset scenarios related to the various devices, with access levels and prerogatives differentiated per user.
