A protocol translator gateway enables data transfer between serial and Ethernet protocols. An extensive library of driv- ers provides easy interoperability between a variety of de- vices used in building automation, HVAC, fire and process control industries.


Dual Serial – Ethernet


The FS-B2510 FieldServer Gateway provides two serial ports and one Ethernet port making it ideal for interfacing either two serial devices or a serial to Ethernet connection. An example is a fire alarm panel using a proprietary manufacturer’s protocol needing to supply alarm information to a building automa- tion system. In a single, comprehensive package the FS-B2510 provides the hardware and software necessary for this translation.  The FS-B2510 includes two serial (switchable RS-232/RS-422/RS-

485) ports and an Ethernet (10/100BaseT) connector to interface to the devices. Configuration files can be downloaded via Ethernet port. All the necessary software and instructions for configuration are supplied with the FieldServer. FieldServer Technologies also offers fee based configuration services.
