The Telemetry Station is a powerful user tool that receives
telemetry data from your XtremeLink« system. This means that data
from your transmitter module, receiver, and any connected sensors can be
shown in real-time as well as having the data recorded, and played back. Besides
these advanced functions, the Telemetry Station hardware can also perform
the same functions of the
XtremeLink« Device Programmer (XDP). This allows you
to change settings and update firmware (if applicable).
The Telemetry Station requires v2.4 or later firmware for
receivers and any version firmware for the transmitter modules.
XtremeLink« 3 channel and 6 channel receivers do not have
telemetry capability, so these receivers will never support telemetry.
To enable telemetry support with your receiver, use the
XDP.EXE program. Put your receiver in programming mode (not binding
mode) so that you can access the settings. Once the EEPROM has been
read, go to the pull down menu and select "ADVANCED MODE". You will
see the TELEMETRY button become available. Click on the TELEMETRY
button. You will now see the sensor access menu, telemetry rate
configuration, and the developer tools. You must enable the
receiver's telemetry support by setting a telemetry rate. This rate
is how often telemetry data is sent from the receiver to the Telemetry
Station. We recommend a rate of 10, which is every 10th frame.
At a typical frame rate of 22ms, this equates to roughly 46 frames per
second. With a rate of 10, the receiver will be sending telemetry
information just a little faster than 4 times per second. The lower
the number, the more often the data will be sent back. Setting this
too low can significantly reduce the amount of bandwidth for other 2.4GHz
systems on the same frequency. This is only a concern when there are
dozens of other systems in use simultaneously on the same frequency
(channel). After you
have set the rate, close the TELEMETRY window and click the UPLOAD TO
EEPROM button to make the change in the receiver. You are now ready
to receive telemetry information!
Run the Scanner (Scanner.exe) program. Turn on your XtremeLink«
system so that you can move servos and such. Now, click on the
"Search for System" button. The RF hardware will be initialized and
then a search will be made for a XtremeLink«
system. If there are multiple XtremeLink«
systems in use, the first one found will be the one that is "locked" on
to. Once a system is found, the information about the transmitter
module and receiver will be shown. This information includes the
IEEE MAC address assignment, frequency (by channel number), number of
servo channels, signal strength of transmitter (as seen by the receiver),
and the receiver battery voltage. Note: if the values for
signal strength and receiver battery voltage are question marks (???) this
is due to you not having enabled the telemetry mode in the receiver (see
above). The transmitter's stick positions (in microseconds) is shown
at the top of the info window and the sensor information is directly below
At any time while you are viewing the system you can click
on the red square button (RECORD) to start recording. Once you are
done recording, press the black square button (STOP). You can then
use the slider bar along with the left and right arrows to look at the
data you just recorded. Note: once you press the STOP button, real
time updates are terminated. You can save this data by selecting
"Save Telemetry Data" from the FILE pull-down menu. You can load
telemetry information saved by selecting "Load Telemetry Data" also from
the FILE pull-down menu.
About 150K of memory (and hard drive space) per minute is
necessary to record both the transmitter and receiver data. So, a 10
minute flight without any sensors would need about 1.5MB of memory.
Even 640MB systems should be able to record hours worth of data before
saving it to the hard drive.
Pressing the ESCAPE key while viewing data in real time
will stop the process and allow you to click the Search for System button
again to look for another
