Remote Site Access Router with ADSL and Ethernet WAN ports.
The RSA-4122 is designed for remote access to sites like electric power substations, roadside cabinets for traffic control and remote surveillance and the like. It provides access to remote terminal units with Ethernet or serial ports.
The RSA-4122 can be used to replace Dial-up and leased line modems and offers high speed Ethernet communications while maintaining support of serial communication. This allows for easy migration to the use of remote terminal units with Ethernet interface and other devices such as remote surveillance cameras while maintaining connectivity to devices with a serial RS232 or RS485 port.WAN ports
Apart from using the DSL line or Mobile network for connection to the internet, the RSA-4122 can also use its Ethernet ports for WAN access via an external modem or router or a fiberoptic internet connection. Both untagged and tagged (VLAN) operation is supported.
The RSA-4122 can be used with an external WWAN modem connected via one of the USB ports. Check with MuLogic for supported devices.Failover operation of WAN ports and interfaces
The WWAN port can be used as primary connection but can also serve as back-up for either the XDSL or Ethernet WAN links.
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 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-4122 can be configured and managed in multiple ways:
The RSA-4122 is equipped with a galvanically isolated power input.
Extended temperature range
The RSA-4122 is designed for operating under extreme temperature conditions.
