Device server switch provides IP connection to legacy serial devices and routing functionality.
Westermo has announced the release of its Lynx DSS compact device server switch for connecting legacy serial control and telemetry systems to the latest IP networks. With low data rate serial communications being replaced by higher bandwidth IP networks, the Lynx DSS helps to preserve any investment in existing systems and add functionality by supporting new equipment that requires additional bandwidth.
Lynx DSS is an industrial Ethernet switch for managing applications with a combination of IP and serial connections replacing the need for multiple units. Powered by an updated version of the Westermo WeOS operating system, the device delivers enhanced serial to Ethernet connectivity support for dual serial networks, modem replacement functionality and Modbus gateways. Legacy devices can be connected via two serial ports; one configured for RS232 and the other for either RS232 or RS422/485.
Two versions are available, the L208-F2G-S2 and L108-F2G-S2. The L108 supports a range of layer 2 switching functions that provide resilient, rapid recovering redundant ring Ethernet networks. The unit has four 10/100 Mbit/s ports and two further ports can be fitted with either Gbit or 100 Mbit SFP transceivers. In addition to these functions the L208 provides additional layer 3 networking functionality including routing, firewalls and VPN remote access. These functions support users wanting to communicate over potentially insecure networks and also help to prevent users inadvertently connecting to the wrong network.
Suitable for deployment in extreme operating conditions, the device is type-tested to meet industrial EMC, isolation, vibration and shock standards and approved for use in industrial applications including Cenelec EN 50121-4 certification for railway trackside installations. The Lynx DSS has a wide operating temperature range from -40 to 70°C, no fan or other moving parts and a full metal IP40 enclosure. The WeOS operating system has been developed as a cross platform solution. Available on the Westermo RedFox, Wolverine, Lynx and Falcon products, it provides a future proof and scaleable solution for industrial networking requirements.
Low power requirements results in a reduction in running cost over the life of the unit and a footprint size of only 100 x 50 mm makes the unit easy to incorporate into machines and existing applications. A wide operating range of 19-60 VDC increases the scope of suitable applications.
