3. Product Description
3.1. Product Description
Lynx DSS is a device server with a managed layer 2 and 3 industrial Ethernet switch,
powered by the Westermo WeOS network operating system. It is the most compact and
has the lowest power requirements in this class of device servers.
Lynx DSS is the most compact, and has the lowest power requirements, in this class of
device servers. It has four pieces of 10/100 Mbit/s ports in addition to two ports which can
be fitted with Gbit or 100 Mbit SFP transceivers and two serial ports. One serial port is
configured for RS-232, the other one can be configured for either RS-232 or RS-422/485.
Lynx DSS is designed for simple use in industrial applications, from the robust DIN rail clip
solution to the configurable fault contact and the industrial level of dual power inputs.
Only industrial grade components are used which gives Lynx DSS an MTBF of 517,000
hours and ensures a long service life. A wide operating temperature range of -40 to +70°C
(-40 to +158°F) can be achieved with no moving parts or cooling holes in the case. Lynx
DSS has been tested both by Westermo and external test institutes to meet many EMC,
isolation, vibration and shock standards, all to the highest levels suitable for heavy industrial
environments and rail trackside applications.
WeOS has been developed by Westermo to offer cross platform and future proof
solutions. For more WeOS functionality, please see the WeOS datasheet.
