M2M Router PRO 4

Industrial smart IoT wireless LTE router and DCU with dual SIM and module option.

The device has 4 Ethernet ports, RS232/RS485 interface and expansion options.onlice & central router management It can be supplied from VDC mains.

The enclosure supports DIN-rail mount, the ports are protected by sealable terminal cover.

It can be used for wireless data transmission of industrial and measurement systems, for collecting data of utility smart meters and for PLC connection (to a remote Scada system), to provide secondary or backup route (wireless network access) for your business.

The device has full remote access, monitoring and maintenance features.

Supplied with the embedded and open source, Linux-based OpenWrt® system, which is easy to configure on the router web user interface.

m2m device manager

We offer to manage the router by our Remote Device Manager® application, which remotely provides continuous central management, QoS monitoringmass configuration / firmware updates.
