With the DSR-211-450 LTE-450 router, inaccessible or mobile outdoor statio-
or mobile outdoor locations that do not have access to the telephone network or ADSL.
networks. Access is wireless via the LTE-450, LTE-M or NB-IoT network.
VPN can be used to establish secure connections between your outstations and your control center.
your control center can be established. The VRRP protocol also enables the redundant connection of the
connection of the outstations via 2 different routers. A restart of the
device is possible remotely by call or timer.
The DSR-211-450 is used for secure transmission in the monitoring and control of supply networks.
monitoring and control of utility networks such as water, gas & electricity networks.
Thanks to the integrated Ethernet interface, Ethernet-based systems can be quickly and easily connected to the LTE.
Ethernet based systems to the LTE-450 / LTE-M / NB-IoT network.
The LTE-450 router is also equipped with RS-232 or RS-485 port. These
interfaces can be used to connect serial end devices as modem, gateway
(Modbus/IEC) or virtual COM port.
