12.3 Using The RFU Utility
Support for downloading new application firmware to the ETH-100 is provided by the
free Rabbit Field Utility (RFU), which is a 32-bit application that runs on Microsoft
Windows platforms. The RFU utility can be downloaded from ICC’s home page at
http://www.iccdesigns.com . The remainder of this section will detail the RFU utility
configuration and firmware download procedures.
12.3.1 Required Files
When first downloaded, the RFU utility files are compressed into one self-extracting
.EXE distribution file. Create a folder (such as c:\RFU), place the distribution file in
this folder, and then execute it. This will extract the following files into that same
folder:
• RFU.EXE (executable download utility)
• RABFIELD.HLP (help file)
• COLDLOAD.BIN (CPU bootstrap firmware)
• PILOT.BIN (pilot BIOS firmware for downloading)
The distribution file is then unneeded and can be deleted if desired. To run the RFU
utility, double-click on the RFU.EXE file icon.
12.3.2 First-time configuration
The first time the RFU utility is run on a computer, several configuration items need
to be confirmed. These configuration items are retained in the computer’s registry
from that point on, so reconfiguration is not required unless certain parameters (such
as which serial port to use on the computer) are changed.
The two configuration items that need to be confirmed are the communications and
bootstrap loaders path. First, select the “Setup…Communications” menu item (refer
to Figure 18).

The Communications Options window shown in Figure 19 then appears. Confirm
that the settings are as shown, with the possible exception of the “Comm Port”
setting, which depends on the COM port you are using. Click “OK” when complete.
