A 10-serial, 2-Ethernet port, protocol translator gateway enables data transfer between serial and Ethernet proto- cols. An ISA slot allows additional driver cards. An ex- tensive library of drivers provides easy interoperability between a variety of devices used in building automa- tion, HVAC, fire and process control industries


Serial – Ethernet


The FieldServer is a protocol translator/gateway which enables devices using one protocol to com- municate with devices using another protocol. An example is a fire alarm panel using a proprietary manufacturer’s protocol needing to supply alarm information to a building automation system.  In a single, comprehensive package the FieldServer provides the hardware and software necessary for this translation. The FS-B4010 Series includes eight RS-232 ports, two RS-485 ports, two Ethernet (10BaseT) ports to interface to the devices. In addition there is an ISA card slot for special driver adapter cards such as LONWORKS®, DH+, Profibus, ControlNet, etc.  All the necessary software and instructions for configuration are supplied with the FieldServer. FieldServer Technologies also offers fee based configuration services. FieldServers are available for various fieldbuses.
