The file names are not unique, so it is possible to
confuse information in file1 through file8 when using
KERMIT. To avoid renaming new files, create different
directories to store the files. KERMIT will rename the
incoming files to prevent overwriting data.
These data files are backed up in DPL script format. It is
recommended to archive collected data to keep a
historical database of vibration levels and diagnostic
problems. Future products will allow this data to be
viewed and trended using an IBM PC/AT or compatible
Loading Data Files Into The CADU
Archived data files are data files which have been transferred from the CADU to the IBM compatible PC for
storage. Perform the following steps to load data files from the PC into the CADU:
On the CADU, place the CADU in the Host Communications mode of operation. (see steps 4b and 4c).
b. On the PC, double-click the RADSCOM icon to execute the RADSCOM program.
c. Select the "Load data or aircraft setup file from the PC to CADU" menu option.
d. Type in the path (e.g., C:\AVADATA\AC_Type\Tail#\Todays Date\file1) of the file to be loaded and press
the <RETURN> key. (When loading "file1" through "file17" the user only has to specify the first file [e.g., file
1]. The RADSCOM program automatically loads the other files [file2" through "file17"].)
e. Follow the instructions displayed on the PC screen. The Kermit program will begin. (If the transfer of data
stops prior to the transfer of all data files, return to the RADSCOM Menu.)
At the completion of the transfer of the last file, press any key on the PC keyboard when prompted to do so.
g. Repeat steps c through f to load additional data, or proceed to step h.
h. Press Q to QUIT the CADU to Host Communications
On the CADU, selection option 1, Continue with Normal Operations.
On the PC, select X to exit RADSCOM.
k. Disconnect the serial cable from the CADU and from the PC
Initializing the CADU RAM Disk
It will not normally be necessary to format the system RAM disk unless something serious has failed or a
battery replacement is not performed properly. However, the procedure is provided in case of a system failure.
During a reformat, all data and aircraft files are deleted, and the required AVA system files are reloaded into the
CADU. The following is the procedure for initializing the CADU RAMDISK using an IBM PC/AT or compatible:
All data files contained on the RAM Disk will be
erased and will have to be reloaded if the following
procedure [initializing the CADU RAM Disk] is
a. On the CADU
(1) Connect an external power source to the CADU (to prevent an inadvertent auto shutdown due to a low
(2) Connect the serial cable between the PC and CADU.
(3) Place the CADU in the Host Communications mode. (see step 4b and 4c).
