The R1520 router from Robustel is a versatile 4G router with 5 x Ethernet ports, GPS and E-mark certification for in-vehicle use. It is also ideal for Smart Cities and Retail applications.

The R1520 router from Robustel is a versatile 4G router with 5 x Ethernet ports, GPS and E-mark certification for in-vehicle use.

Other hardware features include optically isolated digital inputs and outputs as well as a 10-bit analogue input capable of interfacing directly with sensors in the range of 0 to 24Vdc or 0 to 20mA.

R1520 also has a 2-wire RS485 interface for connection to legacy instruments with full support for Modbus. The RS232 port features RTS/CTS lines so the product can accommodate applications that require hardware handshaking.

Despite being cost-effective, the R1520 is a powerful router with high packet-forwarding capability – way beyond the typical requirements of LTE CAT4 networks. The Linux based Operating System, RobustOS, has been developed entirely in-house which leads to a very high standard of technical support and infrequent firmware updates due to modular nature of the OS. Many unique software innovations are built on top of RobustOS, these include:

RobustVPN – highly flexible hosted VPN service so customers can easily enjoy a “fixed IP router”

RCMS is Robustel’s free router monitoring service that is fully compatible with the R1520. It allows customers to see a location overview of their routers quickly and simply on a map.Features such as data usage, signal strength, current network and much more can then be viewed on a per router. Over-the-air updates are supported for Firmware, router configuration and Apps serving as essential ‘insurance’ if anything was not quite right during deployment.
