Connecting Step 1.
Ensure that your sensors is
activated. For HRM, this is typically done by putting
the strap around your chest. For bike Sp/Cad
sensors, typically by spinning the wheel or pedals.
Connecting Step 2.
Providing the sensor is in
range and activated, the Active should "see" it on
the Bluetooth devices screen. If not, please press
Refresh and the name of sensor should appear, in
the example right: "Wahoo HRM v2.1". Use the joy
stick to cursor up and down to your desired sensor
device. Either press the Select button, or centre
press the rocker pad and a black tick will indicate
that the sensor has been "Selected".
Please Note;
Bluetooth allows only one of each
type of sensor to be selected at any one time. You
can have a HRM and a Sp/Cad sensor selected,
but not two HRM's.
Connecting Step 3.
Wait for a short period and
the black tick should turn blue. This indicates that
your selected LE device has now "connected"
and sensor data can be collected. During the
connection process, the BT icon on the status bar
should flash blue/grey and then turn solid blue
when the connection is made.
Troubleshooting.
Very occasionally Bluetooth can be temperamental!
If a connection is not made on the first attempt -
deselect the BT LE device, check that your sensor
is activated and in range, and then reselect the
device. Failing that, turn the Bluetooth fully off,
then back on again, and reattempt the connection
process. If that continues to fail, please connect
Satmap support.
Connecting Step 4.
Once a blue "connected"
tick has been observed, you sensor will then
pass data to the Active 20. This data may then be
displayed in the 2 & 4 data boxes that appear on
the GPS MAP screen. To set this up, you will need
to select SETTINGS / 2/4 BoxLayout and the HRM
Software v3.13.11
data item (20.HRM).
Data Types : HRM.
Heart rate data is
displayed as "beats per second". Future editions
of software will display Heart Rate Zones, and
the such like.
Data Types : Cadence.
This is a measure of
the pedal revolutions per second on a bike.
Data Types : Wheel Speed.
to using speed calculated by GPS position
movement, cyclist often use "wheel speed" as a
reliable backup. This is especially useful if a GPS
lock is difficult for any reasons (e.g. very thick
woodland or the urban jungle).
Set up for Wheel Speed.
This relies on
a default value for the wheel circumference,
which is then multiplied by the wheel revolutions
output from the sensor. The default setting
is 2,096mm, and this can be changed in the
SETTINGS / Cycling screen. Use the rocker
pad to navigate the numbers and set the values.
Data Output.
HRM and cadence data will be
stored on the Active 20. After your activity, save
your data for later upload. This is done via the
TRIPLOG / Menu / Convert options. Your data
containing the HRM and cadence values will
be stored in a TCX file (e.g. MyRoute1.tcx). You
will be able to see these files when you use the
SatSYNC PC application to upload your data.
About TCX files.
This is an industry standard
format that is accepted by a wide variety of 3rd
party activity storing and sharing web sites.
These TCX files can contain location and speed
data, along with a wide variety of fitness related
data items.
