Communication interfaces: industry-standard or PDI5025-compatible
The FDI2056 can be configured to use an Ethernet or an RS-232 interface to connect to the host computer. The Ethernet interface uses the industry-standard VXI-11 and SCPI protocols, and is therefore compliant with the standards used by most major instrument suppliers. Using this interface, the full functionality is easily accessible using a standardA standard is the internationally agreed-upon physical representation of a unit. For example, a caesium clock is the standard for... More VISA (Virtual Instrument Software Architecture) library.
The RS-232 interface provides a command set compatible with the PDI5025, providing backwards compatibility with the PDI5025 to avoid rewriting your software.

More FDI2056 software for Windows or Mac, or integrate the FDI2056 into a data-acquisition system using Metrolab’s FDI2056 API. Unless they’d like to shrink system size by eliminating the need for a separate computer.
The FDI5026 includes a LabVIEW application to handle common data acquisition, correction, analysis and recording tasks. For special requirements, custom programming is easy, with full documentation, an Application Programming Interface (API), and source code. For industrial environments, the software can be hosted on the instrument’s industrial computer, eliminating the need for a host computer.
Ready for the future
The FDI2056 is designed with future enhancements in mind, and is upgradable on all levels – hardware, firmware and software. Users can download upgrades from the Metrolab web site and install them in the field.
