Program description: Telemetry menu
Telemetry
The “Telemetry” menu is used to call up and program
transmitter and receiver data, and data generated by
optional telemetry sensors (see Appendix), in real time.
Receiver data are transmitted to the transmitter via the
HoTT receiver’s integral downlink channel.
One telemetry sensor can be connected to the Telem-
etry input of the following receivers: GR-12S HoTT
(Order No. 33505), GR-12 HoTT (Order No. 33506) and
GR-16 (Order No. 33508). Two telemetry sensors can
be connected to the HoTT GR-24 HoTT receiver (Order
No. 33512).
Since this and future receivers can be updated by the
user, the associated “Telemetry” menus can constantly
be kept up-to-date, and expanded with the introduction
of additional functions or languages in future.
Note:
If you register your product under http://www.graupner.
de/en/service/product_registration you will automatically
be informed about new updates by e-mail.
Before updating the transmitter software you should
always back up all occupied model memories to a
compatible laptop or PC in order to avoid a possible loss
of data.
In addition to the back-ups mentioned above, fi rmware
updates are transferred using the transmitter’s PC
socket and the optional USB adapter, Order No. 7168.6
and the connecting lead, Order No. 6466.S, in con-
junction with a PC running the Windows XP, Vista or 7
operating system.
The programs required for this and related information
can be found in the Download area for the correspond-
ing products at the website www.graupner.de. We
always recommend that you load the latest fi rmware into
your equipment, to ensure that your system is constantly
kept up-to-date.
Important information:
These instructions cover the functions available at •
the time of going to press.
As mentioned in the sections entitled “Binding mul-•
tiple receivers” on pages 61 and 70, it is possible to
bind more than one receiver per model. However, in
subsequent operations only the receiver which
was bound last is able to make a telemetry con-
nection to the transmitter. On the other hand, this
also means that only the last bound receiver can be
addressed using the Telemetry menu. You may there-
fore need to change the binding sequence before you
can enter settings which relate to a particular receiv-
er.
When setting up the radio control system, please •
ensure at all times that the transmitter aerial is
an adequate distance from the receiver aerials.
A safe distance is about one metre. If you ne-
glect this, you risk interference with the downlink
channel, and consequent malfunctions.
Since the transmitter and receiver only exchange te-•
lemetry data after each fourth data packet, data
transmission inevitably requires a certain amount of
time, which means that there will be some delay in
responding to button-presses and set-up changes.
This does not constitute an error.
Changes to model and sensor programming must •
only be carried out when the model is on the ground.
Do not make any alterations unless the motor is
switched off and the fl ight battery is disconnected.
If you ignore this, unwanted effects of programming
changes cannot be excluded.
For example, if you accidentally initiate an active ser-
vo test at the receiver, the model could crash and
cause personal injury or property damage. Please
see the Safety Notes on pages 3 … 6 of this manual
and the various individual instructions.
All settings which you enter using the “• Telemetry”
menu, such as Fail-Safe, servo direction, servo trav-
el, mixer and curve settings etc., are stored exclu-
sively in the receiver, and are therefore carried over
if you install the receiver in a different model. For this
reason we strongly recommend that you re-initial-
ise your HoTT receiver if you wish to use it in another
model; see “Reset” on page 33.
We therefore recommend that you program directions •
of servo rotation, servo travel, mixer and curve set-
tings using only the mx-12-specifi c standard men-
us “Servo settings” (page 72), “Free mixers” (page
107) and “D/R Expo” (pages 82 and 84). If you ignore
this, the settings may overlap and interfere with each
other; in the most favourable case this can result in
confusion when operating the model, and in the least
favourable case it could cause problems.
The channel-mapping function of the • mx-12
HoTT’s integral “Telemetry” menu can be used to
share out control functions between multiple receiv-
ers in any way, or even to assign the same control
function to several receiver outputs; for example, you
may wish to operate each aileron with two servos in-
stead of just one, etc. Once again we strongly re-
commend that you act as cautiously as possible
when carrying out the programming.
