RSA-1020DW1

4G (LTE Cat.1) Cellular Remote Site Access Router.


 

Introduction

The MuLogic RSA-1020DW1 is a cellular router for providing access to
unmanned remote locations such as power substations, traffic management systems and various other remote site automation equipment.
 
The unit is equipped with a cellular wireless WAN modem that supports 4G, 3G and 2G cellular networks and offers wireless data rates up to 10 mbit/s (LTE Cat.1).

In addition to an Ethernet port, the RSA-1020DW1 incorporates 2 independent serial port gateways that can be used for remote access to devices with a serial interface. One serial gateway connects to an RS232 port, the other to RS485.

The unit is designed for industrial applications and is powered from low voltage DC or AC power sources.

The
RSA-1020DW1 operates over a temperature range from -40C to +70C.

Application Areas

Remote site access
The RSA-1020DW1 is designed for access to unmanned remote sites like electric power substations, roadside cabinets for traffic control, remote surveillance etc. The unit provides connectivity for Remote Terminal Units, PLCs and other equipment and supports both Ethernet and serial ports. Various options for secure VPN tunnels like IPsec and OpenVPN are available. In combination with GRE or OpenVPN Layer2 tunnels, all possible layer2 and layer3 network protocols can be transported securely.

Remote Machine access

Machine builders often offer remote access support and diagnostics for their installed machines. However, network security policies of a factory or plant may make direct remote access very cumbersome or even impossible. To overcome these situations, the RSA routers and connected machines can be made accessible via a secure 3rd party cloud service.
The RSA router in the factory can make connection to the cloud platform via the cellular network, thus totally bypassing the factory network.
The cloud platform offers access to the remote machines via smart phones, tablets or PCs connected to the internet and without the need to create your own VPN network. Via the platform, web based services are available for accessing the router's user interface and web servers or VNC servers of attached machines.


Cellular Wireless WAN

The RSA-1020DW1 incorporates an internal wireless WAN (WWAN) modem for internet connectivity via cellular networks worldwide.


Serial port gateways

The integrated Serial Port gateways offer remote access to the unit's serial ports.
One gateway connects to the RS485/RS422 port, the other to the RS232 port.
Combined operation of RS232 and RS485 to a single gateway is also possible.

The network connection to the serial port gateways allows for the use of various tools like "virtual com port drivers", direct IP socket connection or dedicated application software. Also other
"serial to Ethernet converters" or another Mulogic router can be used. In addition, the serial ports can also be accessed by means of a telnet connection.


Information and Access Security: IPsec, OpenVPN and Firewall.
As the unit in most cases will be connected to the public internet, extra security features such as IPsec and OpenVPN are supported. IPsec and OpenVPN protect against unwanted access and eavesdropping of the data. With IPsec and OpenVPN encrypted virtual tunnel connections can be created. Only devices at the end-points of the tunnel can communicate and the data is protected from eavesdropping.

A single
RSA-1020DW1 can support multiple IPsec or OpenVPN tunnels.
The OpenVPN tunnels can operate in routing mode (layer-3) but can also be used to transparently bridge Ethernet frames (Layer-2).

The unit's firewall features are used for static or dynamic NAT routing (port forwarding and IP masquerading) and blocking or granting access to the devices attached to the unit and the unit's configuration and management interface.
This makes it possible to block all access
from unknown IP addresses. In addition, several options are available to limit the rate of incoming or outgoing data as protection against DoS attacks.

Configuration and remote management.
The RSA-1020DW1 can be configured and managed in multiple ways:
  • Web browser (http and https).
  • TR-069 CWMP.
  • HTTP Post for scripted configuration and control.
  • IXplatform.
  • Command line interface via telnet, SSH, or serial port.
  • SNMP manager.

Device power supply
The RSA-1020DW1 is equipped with a galvanically isolated power input.
Three voltage ranges are available:
  • 11-36Vdc/11-28Vac.
  • 18-60Vdc/18-30Vac.
  • 18-72Vdc.
For mains power operation (100..240Vac) an external power adapter or power supply is used.

Extended temperature range
The RSA-1020DW1 is designed for operating under extreme temperature conditions.
It is suitable for operating at ambient temperatures ranging from -40C to +70C.
