Rabbit RFU Field Utility User Manual

Dynamic C Module
Rabbit Field Utility
The Rabbit Field Utility (RFU) will load a binary file created by Dynamic C to a Rabbit-based
controller. It can be used to load a program to a controller without Dynamic C present on the host
computer, and without recompiling the program each time it is loaded to a controller.
The Dynamic C installation created a desktop icon for the RFU. The executable file, rfu.exe,
can be found in the subdirectory named “Utilities” where Dynamic C was installed. Complete
instructions are available by clicking on the Help button within the utility. The Help document
details setup information, the file menu options and BIOS requirements.
