Remote Site Access Router with ADSL/VDSL2, Ethernet and cellular wireless WAN ports

The MuLogic RSA-4222W is a router for access to remote locations such as power substations, traffic management systems and various other remote site automation equipment. The unit is equipped with an ADSL/VDSL2 port, a 2G/3G or 2G/3G/4G Wireless WAN port and 4 Ethernet ports with VLAN support that can be configured as LAN or WAN port. Two USB2.0 ports are available for connecting an external wireless WAN modem and USB devices like memory and interface devices for extra Ethernet and serial ports. The RSA-4222W 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 an RS485 port. The unit is designed for industrial applications and is powered from low voltage DC or AC power sources. The RSA-4222W operates over a temperature range from -40°C to +70°C.
