With the DSR-211-L LTE/UMTS router, inaccessible or mobile outdoor stati
or mobile outdoor sites that do not have access to the telephone network or ADSL can be
integrated into central networks. Access is wireless via the GSM/UMTS or LTE network, which is available worldwide.
network, which is available worldwide. Theoretically, LTE allows speeds of up to
speeds of up to 100Mbit/s in the downlink and 50Mbit/s in the uplink are theoretically possible.
VPN can be used to establish secure connections between your outstations and your control center.
your control center. The “Dual SIM” function ensures a fail-safe connection.
connection is guaranteed. In addition, the VRRP protocol enables redundant
connection of the outstations via 2 different routers. A restart of the device can be
remotely via SMS, by phone call or by timer.
The DSR-211-L is used for monitoring water, gas and electricity networks, for secure transmission of
and power networks, secure data transmission for POS terminals and ATMs,
video and media transmission (digital signals), and remote maintenance of vending machines
and other industrial machines, systems and devices.
If LTE is not available, the downward compatibility of the router offers
UMTS, GPRS and EDGE data services in 3G/GSM networks offers maximum availability.

Thanks to the integrated Ethernet interface, Ethernet-based systems can be quickly and easily connected to the Internet.
Ethernet-based systems to the Internet quickly and easily.
The LTE router is also equipped with RS-232 or RS-485 screw connection.
These interfaces can be used to connect serial terminals as modem or
VirtualCOM port can be used.
