Our example uses townhall files 1, 2 and 3. As stated these are selected by holding the control key and
selecting each file. Upon clicking Open you will be returned back to the control screen where the selected
files will be displayed in the downloaded files list.
If required, files can be removed by selecting them on the list and clicking remove file.... Once all the re-
quired files are present click on Analyse Downloads >> and follow the steps in Example 1 section 5.1.4.
Appendix A: PANCOM File Corruption
File corruption is where the data stored in a file is different to the data that is expected. The corruption that
occasionally effects EDA panel downloads is a loss in the synchronisation between the panel and the PC
being downloaded to. The result is almost always a loss of a small portion of the data. EDA device down-
loads have two formats, one for the dual frequency M100 system and another for the single frequency
M200 system. These formats are shown below and also in the two attached download examples.
M100 lines are of the following format:
D:0001 T:----------- S:20 A50 I-- F-- R-- DEVICE
M200 lines follow this similar format:
D0001 T01 S54 SMOKE T01
The numbers following D in both cases indicate the device number, the numbers following the S indicate
signal strength. More often that not corruption consists of a few missing characters which upon user analy-
sis can easily be inserted. Occasionally the corruption may cause the loss of whole lines of data in which
case another panel download is recommended.
In order to pass the corruption check the test characters from the line must be in the correct position rela-
tive to the start of the line, hence a missing hyphen (-) between the T: and S: would cause the S character
to shift left - failing the corruption check.
A character inserted at the start of the line would also cause the line to fail since all test characters would
be shifted right.
Corrections made to corruption using the PANCOM software are only temporary and need to be performed
each time the data is processed. For a more permanent correction the source file should be opened using
a text editor such as NOTEPAD and corrected, failing that another download should correct the problem.
