Feature rich protocol translator enables data transfer between LONWORKS® protocol and an extensive library of other serial and Ethernet protocols used in a building automation, HVAC, fire and process control industries

LonWorks® – Serial – Ethernet

FieldServer LONWORKS® Gateway is a protocol translator which enables devides using legacy protocols to communicate with LONWORKS networks. An example is a fire alarm panel using a proprietary manufacturer’s protocol needing to supply alarm information to a LONWORKS network. In a single, comprehensive package the FSBridge provides the hardware and software necessary for this translation. In addition to the LONWORKS connector, the FS-B2011 includes a serial (RS-232 or RS-485) and Ethernet (10BaseT) connector. Configuration files can be downloaded via the serial or Ethernet port. All the necessary software and instructions for configuration are provided with the FS-B2011. FieldServer Technologies also offers fee based configuration services. Other FieldServers are available for other fieldbuses or for multiple port applications.
