RuggedWireless RS920W



The RuggedWireless™ RS920W is an industrially hardened Wireless Serial Device Server that has been specifically designed to operate reliably in electrically harsh and climatically demanding environments. The RS920W features a wireless LAN (WLAN) interface combined with 2 serial ports and one Ethernet over VDSL (EoVDSL) interface. The RS920W allows you to connect RS-232/422/485 serial devices at up to 230 kbps and for wireless access and control via an IEEE 802.11i wireless LAN. The RS920W can also act as a wireless access point and in combination with the EoVDSL interface, can aggregate many devices at a remote location back to the central control room using existing telephone grade cable (or other legacy serial cabling) at distances of up to 4km.

The RS920W functions as a wireless "client/bridge" within an IEEE 802.11b/g compliant WLAN. This allows the RS920W to transfer data for connected serial port and Ethernet devices via an installed Wireless Access Point. The RS920W is capable of wireless data rates of up to 54Mbps whose bandwidth is available for the combined device traffic volume emanating from two serial ports and two Ethernet ports. Static authentication support is provided by WPA-PSK. For authentication by an access point and a RADIUS server, the RS920W supports IEEE 802.1X/ RADIUS for wireless user traffic and distributing dynamic encryption keys. All wireless communications are protected by "hardware accelerated encryption" to ensure high performance when using strong encryption and authentication protocols such as WPA/TKIP and WPA2/802.11i. The web management interface is protected using SSL.

The RS920W has an operating temperature range of -40 to +85°C without the use of internal cooling fans allowing it to be placed in almost any location. The RS920W also has an integrated power supply with a wide range of voltages for worldwide operability, and is compliant with EMI and environmental standards for utility substations, industrial manufacturing, process control and intelligent transportation systems applications.

The RS920W is backed by a five year warranty and unsurpassed technical support.
