Remote Site Access Router with ADSL, Ethernet and cellular wireless WAN ports.
Remote site access
The RSA-4222W4 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 tunnels or secure Layer2 tunnels, all possible layer2 and layer3 network protocols can be transported.
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 factory network without the need for changing or adding firewall rules. Alternatively,
the routers can have their own connection to the outside world via xDSL or WWAN, 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-4222W4 incorporates an internal wireless WAN (WWAN) modem for internet connectivity via cellular networks worldwide.
The WWAN port can be used as primary connection but can also serve as back-up for the xDSL WAN link.
Failover operation of WAN ports and interfaces
All WAN interfaces can be used as primary WAN or back-up WAN interface.
Serial port gateways
The integrated Serial Port gateways offer remote access to the unit's serial ports.Information and Access Security: IPsec, OpenVPN and Firewall.
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 or SSH connection.
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.
The RSA-4222W4 can be configured and managed in multiple ways:
The RSA-4222W4 is equipped with a galvanically isolated power input.
Extended temperature range
The RSA-4222W4 is designed for operating under extreme temperature conditions.
