10.2. Viewing recorded telemetry data using Editor
•
Use Editor to open one of the files named "MSB_xxxx.csv".
You will find these files on the Micro SD card in the
"Alle00xx" folder.
•
When you open the.csv file using Editor, you will see a
display similar to that shown below:
$SETUP1;Time; A:00; A:01;;;;;;; A:08; A:09; A:10;
$SETUP2;sec ; V;% LQI;;;;;;;
$D;0003,25;5,0;100;;;;;;;0;0;-0,1;*DC
$D;0003,28;5,0;100;;;;;;;0;0;-0,1;*C8
$D;0003,36;5,0;100;;;;;;;0;0;0,1;*57
$D;0003,44;5,0;100;;;;;;;0;0;0,1;*52
$D;0003,53;5,0;100;;;;;;;0;0;0,1;*8A
$D;0003,62;5,0;100;;;;;;;0;0;0,1;*BD

$D;0003,79;5,0;100;;;;;;;0;0;0,1;*49
$D;0003,88;5,0;100;;;;;;;0;0;0,2;*ED
$D;0003,96;5,0;100;;;;;;;0;0;0,2;*96
•
Description of the data structure:
•
The first line records the headings, i.e. the measured
time points ("Time") and the sensor addresses ("A:00",
"A:01", ..., "A:15") which are in use.
•
The second line lists the units associated with each
heading.
•
The individual time points are listed line by line, from top
to bottom (seconds as comma / decimal point values).
•
To the right of each time point, and separated by a semi-
colon, there is a separate entry in the .csv file for each
time point and each telemetry value, i.e. for addresses 0
to max. 15.
•
If data have been recorded at each time point for the
individual addresses, then the associated measured
values are indicated. If an address is not in use, then the
corresponding entry is empty.
!
Note: the actual number of columns in the .csv file is
dictated by the highest occupied address which has been
assigned for the output of telemetry values: if, as in our
example, address 10 is the highest address in use, the
(empty) columns for values 11 - 15 are not shown.
•
The initial line components ($SETUP or $D) indicate that
a heading and / or data follow. The final line components
(e.g. *DC, *C8, ...) are checksums.
•
Reading the recorded telemetry data:
•
At the time point 3.25 seconds a value of 5.0 Volt was
logged at address 0.
•
An LQI value of 100% was also measured at address 1.
•
At this time point there are no measured values for
addresses 2 to 7.
•
At this time point addresses 8 and 9 each indicate a
value of 0 metres.
•
At the time point of 3.25 seconds the model was
descending at a rate of 0.1 metres per second; this can
be seen from the entry at address 10.
!
Note: it is safe to connect and disconnect sensors even
when the system is operating, i.e. you do not need to switch the
RC system OFF beforehand. The sensor values which you add
or remove are reflected in the "width" of the .csv file: the.csv file
is either expanded or reduced accordingly.
10.3. Analysing the recorded data using Microsoft
Excel or LogView
If you wish to assess the recorded data in detail, and perhaps
analyse them in graphic form, PC programs such as Microsoft
Operating Instructions
FlightRecorder
Excel, Open Office or LogView are a good choice. The LogView
program can be downloaded from http://www.logview.info.
These PC programs can be used to display and assess the
recorded telemetry data to suit your personal requirements.
For example, it is much more convenient to display telemetry
data using Microsoft Excel than it is to use Editor, not least
because it is easy to display the data in clear tabular form, and
to suppress columns which are of no interest (e.g. checksums).

10.4. Visualising the flight path using Google Earth
If you use a MULTIPLEX GPS unit, then the Export function of
the "LogView" PC program can be used to export the recorded
data to Google Earth.
This even makes it possible to display your model's flight path in
Google Earth! In this case the .csv file (see example in
is expanded by the associated GPS data.
The following components are required in order to record the
GPS position in the stored file:

11.
AND
The FlightRecorder is fitted with a two-colour LED status
indicator capable of lighting up green or red.
11.1. Initialisation phase
The initialisation phase of the FlightRecorder starts when the
power supply is connected and / or the Micro SD card is in-
serted, and lasts just a few seconds.
During this period the LED status indicator lights up green, then
goes out briefly before glowing a constant green.
11.2. FlightRecorder installed in a model
If the FlightRecorder is installed in a model, and if telemetry data
are logged after the initialisation phase is completed, the LED
status indicator flickers green at a high rate.
If telemetry data are present, but the assigned transmitter switch
is at the "Stop" position, no telemetry data are recorded. During
this period the LED status indicator glows a constant green.
11.3. Using the FlightRecorder on the ground
When the initialisation phase is completed, telemetry data are
logged. This state is indicated by the LED status indicator
flashing green at a slow rate (approx. once per second).
If there are no sensor data at the transmitter or RF module port,
then the green LED status indicator only lights up once briefly.
11.4. Error Codes
If the FlightRecorder's LED status indicator flashes red, this
indicates an error state:
