The G500XLT RS-485 multiprotocol communication interface allows information to be transferred seamlessly between a Galt Electric G500 series inverter and several different RS-485-based fieldbus networks with minimal configuration requirements. The interface installs directly onto the inverter’s control board, and presents a pluggable, screw-style terminal block for connection to the RS-485 network.

PLC-style logical, arithmetic and filtering data manipulation operations, called Database Logic, allow the construction of complex autonomous data conditioning and control functions. Configurable network timeout actions can also be programmed that allows parameters to have their own unique "fail-safe" conditions in the event of a network interruption. The option card also supports a versatile Generic Serial communication driver which allows integration with any serial device including proprietary or custom protocols using ASCII and/or binary encoding formats.
