The RSA-1020DW4 is designed for remote site access to electric power substations, roadside cabinets for traffic control and remote surveillance, and provides access to remote terminal units with an Ethernet port or serial port.
Apart from using WWAN modem for connection to the internet, the RSA-1020DW4 can
also use one of its Ethernet ports for WAN access. In this way an external modem or fiberoptic internet connection can be used.
The RSA-1020DW4 incorporates an internal cellular wireless WAN (WWAN) module.Failover operation of WAN ports
This can be used as primary connection but can also serve as back-up connection for Ethernet WAN links.
The RSA-1020DW4 is equipped with an Ethernet WAN and a Wireless WAN port.
The integrated Serial Port gateways offer remote access to the unit's serial ports.Information and Access Security: IPsec 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 (e.g. "WinSock") or dedicated application software. Also other "serial to Ethernet converters" or another Mulogic ADSL 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 VPN are supported. IPsec protects against unwanted access and eavesdropping of the data. The IPsec feature creates an encrypted virtual tunnel connection over the internet. Only devices at the end-points of the tunnel can communicate.
The RSA-1020DW4 can be configured and managed in multiple ways:
The RSA-1020DW4 is equipped with a galvanically isolated power input.
Extended temperature range
The RSA-1020DW4 is designed for operating under extreme temperature conditions.
