The HART protocol enables two-way digital communication over the same wires as the 4-20mA analog signal without disturbing the 4-20mA signal. The bi-directional communication provides digital data access between field instruments and host systems. A host can be any software application from a technician’s hand-held device or laptop to a plant’s process control, asset management, safety or other system using any control platform. The HART Device Description (DD) file describes specific features and functions of a device.
The Kurz DD files can be downloaded by clicking on the button below.



A PROFIBUS GSD file (General Station Description) provides a way for a configuration tool to automatically get the device characteristics of PROFIBUS instrument.
The Kurz GSD files can be downloaded by clicking on the button below.


The Windows USB driver allows communication from a B-Series device to a computer via a USB cable. B-Series devices include the 454FTB, 454FTB-WGF, 504FTB, 534FTB,and K-BAR 2000B product lines. Depending on the Windows operating system, internet access, and the Kurz device, the necessary USB driver might be downloaded and installed automatically. The barcode ID on the B-Series device sensor control board determines the correct USB driver. The barcode ID is located in the device menu (Display mode, option 33), in the configuration file (in the Electronic Board Barcode field), and on a label on the sensor control board. If the barcode ID is C51938 or higher, use the FTDI USB driver. The FTDI USB driver is a 64-bit compatible virtual COM port (VCP) driver available on the FTDI Chip website ( or you can click the link below. Kurz devices that use the FTDI driver started shipping in 2012.



Kurz MODBUS Client is a software program that can be used to demonstrate the MODBUS protocol capability of the Kurz B-Series and earlier devices to provide real-time trending graphs and file data logging from multiple meters. This download is for V1.30



The KzComm software application uses the XMODEM or MODBUS protocols to communicate with Kurz devices. It is used to transfer the configuration file from the computer to the Kurz device or from a Kurz device to the computer. It is read/write compatible with B-Series (FTB), FT and Portable devices and Model 155 systems using KAS 6.81 firmware, and it is read-compatible with pre-KAS 6.81 releases. The Read-Only version allows the logs and configuration file to be transferred from the device to the computer but will not allow changes to be made to the connected device.

Note: The download package (.ZIP) includes the current KzComm and Tera Term applications and USB drivers for B-Series devices. The KzComm User’s Guide (.PDF) is available in the KzComm folder after installation and through KzComm’s Help menu.

Upload/Download is required for Model 155 systems using KAS 6.60 firmware and older on 32-bit Windows computers running Windows XP, Windows 2000, and older operating systems.


Tera Term is a free software terminal emulator program that supports communication with Kurz B-Series devices. It emulates various terminals (such as DEC VT100 and VT382) and supports telnet, SSH 1 & 2, and serial port connections. It also has a built-in macro scripting language and a few other useful plugins. The most current version, user manuals, and support links are available on the developer website (

Note: Tera Term can be installed during the KzComm installation process.
