1. GENERAL NOTE

When switching on or adjusting the radio control system it is essential to keep the transmitter aerial at

least 15 cm away from the receiver aerials at all times. If the transmitter aerial is too close to the receiver

aerials, the receiver will be overloaded, causing the red LED on the receiver to light up. The transmitter

responds by emitting a beep once every second; the red LED also goes out. The radio control system

is now in Fail-Safe mode.

If this should occur, simply increase the distance between the aerials until the audible warning signal

ceases, and the red LED on the transmitter lights up again; at the same time the red LED on the receiver

should go out.

2. FUNCTIONS

2.1.Binding

When you wish to use the Graupner HoTT 2.4 GHz receiver with a particular transmitter, the ﬁrst step

must always be to “bind” the unit to “its” Graupner HoTT 2.4 GHz RF module (transmitter).This “binding”

procedure only needs to be carried out once for each combination of receiver and RF module. The units

supplied in the set are already bound to each other at the factory, i.e. the binding procedure described in

the following section only needs to be carried out when you wish to use an additional receiver. However,

it can also be repeated at any time if required, e.g. after changing transmitters. When binding is required,

this is the procedure:

• Switch the transmitter and receiver on.

• Locate the BIND / RANGE button on the back of the transmitter, and hold it pressed in while you

press and hold the SET button on the receiver. Both LEDs on the back of the transmitter now glow

constantly, and the red LED on the receiver ﬂashes.

• Under normal circumstances the ﬂashing red LED on the receiver will cease to ﬂash and switch to

a constant green within about ten seconds. This indicates that the binding process is complete. You

can now release both buttons, and your transmitter / receiver combination is ready for use.

• However, if the red LED on the receiver continues to ﬂash for longer than ten seconds, then the

binding process has failed. If this should occur, repeat the whole procedure.

2.1.1.Binding“ multiple receivers in one model

If required, it is also possible to bind multiple receivers to the transmitter for a particular model. The ﬁrst

step is to bind each receiver individually using the procedure already described.

When the system is in use, the receiver which was bound last is the Master receiver. Any telemetry sen-

sors installed in the model must be connected to this unit, as only the Master receiver transmits sensor

data using the downlink channel. The second and all further receivers operate in parallel with the Master

receiver but in Slave mode, with the downlink channel switched off.

The control functions can also be distributed amongst multiple receivers; this is carried out using the

Channel Mapping function of the SMART-BOX (Order No. 33700). In the same way it is possible to as-

sign one control function to multiple receiver outputs; a typical example would be the use of two servos

for each aileron instead of only one, etc.

2.2.Range checking

The method of checking the effective range of the Graupner HoTT 2.4 GHz system is described below.

We recommend that you ask a friend to help you with this procedure.

After binding the receiver to your transmitter, switch the transmitter and the receiver on, and wait until

the green LED on the receiver lights up.

• Install the bound receiver in the model in its ﬁnal intended position.

• Switch the RC system on, so that you can observe the movement of the servos.

• Set up the model on a ﬂat surface (pavement, closely mown grass or earth), and ensure that the

receiver aerials are located at least ﬁfteen cm above the ground. This may require a support for the

model.

• Hold the transmitter at hip-height, away from your body, but do not point the aerial directly at the

model; instead turn and / or angle the aerial tip so that it stands vertical, and keep it there for the

duration of the range check.

• Locate the BIND / RANGE button on the back of the transmitter, and press it to initiate range-check

mode. Hold the button pressed in until the transmitter starts to beep at a regular rhythm; the red and

green LEDs adjacent to the BIND / RANGE button now ﬂash alternately.

• Walk away from the model, operating the transmitter sticks constantly. If you detect an interruption

in the link within a range of about ﬁfty metres, stand still and attempt to reproduce it.

• If the model is ﬁtted with a motor, switch it on in order to check whether the power system is gene-

rating interference.

• Continue to walk away from the model until you reach the point where perfect control is no longer

possible.

• Now press the BIND / RANGE button on the transmitter once more; this terminates range-check

mode manually, and the model should respond normally to control commands. If this does not occur

with 100% reliability, the system should not be used. Contact your local Service Department of

Graupner GmbH & Co. KG.

• Range-check mode is usually terminated manually when the user presses the BIND / RANGE but

ton, but it terminates automatically after about ninety seconds in any case. The red LED now glows

constantly again, while the green LED either glows constantly or ﬂashes continuously, according to

the Country setting.

• We recommend that you check effective radio range before every ﬂight. While you are carrying

out the check, simulate all the servo movements which will take place when the model is in ﬂight.

The ground range must always be at least ﬁfty metres in order to ensure safe, reliable model con-

trol.

Note:

Range-check mode is usually terminated manually when the user presses the BIND / RANGE button,

but it terminates automatically after about ninety seconds in any case.

CAUTION:

During normal operations (i. e. when controlling a model) never press and hold the programming

button on the transmitter module!

2.3.Fail-Safe function

In its default state (as delivered) the receiver is set to “Hold” mode, i.e. if a fail-safe situation occurs, all

the servos connected to it maintain the last position detected as valid. In this mode the red LED on the

receiver lights up when interference occurs, and the red LED on the transmitter goes out. The transmit-

ter also starts beeping about once per second as an audible warning.

You can exploit the safety potential of the fail-safe option by at least programming the throttle channel to

respond to a fail-safe situation: the throttle channel of an engine-powered model should be set to idle,

the throttle channel of an electric-powered model to “stop”, and the throttle channel of a model helicopter

to “Hold”. If interference should occur, these settings will help prevent the model ﬂying out of control,

possibly causing personal injury or property damage.

IMPORTANT:

The two functions “Binding” and “Range check” described above can be used regardless of the method

you last employed to program the transmitter, i.e. using the programming button or the SMART-BOX;

neither of these two options causes signiﬁcant changes to the settings saved in the receiver. However,

02 Getting Started Graupner HoTT 2.4

if you call up the Fail-Safe function using the programming button as described below, this resets ALL

the settings of the SMART-BOX at the Fail-Safe screen (RX FAIL SAFE) - and this includes the settings

available through the facilities of the programming button. At the same time the Country setting will

revert to Universal if you have previously selected “France” using the programming button - see below

under “2.4”. You MUST therefore select the Country setting again if necessary. For this reason, where-

ver possible it is always best to maintain your programmed settings using the SMART-BOX.

Switch your receiving system on. Locate the BIND / RANGE button on the back of the transmitter, and

hold it pressed in while you switch the transmitter on. Release the button again once it is switched on.

You can now call up the desired Fail-Safe mode (Fail-Safe on / off, Hold, or Standard) by cycling through

the modes with a brief press of the BIND / RANGE button:

• Fail-Safe mode: when you press the BIND / RANGE button, the transmitter beeps once; the red

and green LEDs glow constantly.

It is now possible to program positions to which the servos will move in a Fail-Safe situation; this

occurs after a “Hold” period of 0.75 seconds: move the corresponding transmitter controls (sticks,

rotary knobs, INC / DEC buttons etc.) to the desired Fail-Safe positions SIMULTANEOUSLY, then

hold the BIND / RANGE button pressed in for three to four seconds. When you release the button,

both the red and green LEDs should light up constantly, and the transmitter should not emit an au-

dible signal: the transmitter now reverts to Control mode. If this does not occur, repeat the procedu-

re.

• Hold mode (recommended for model helicopters): when you press the BIND / RANGE button,

the transmitter beeps twice; the red LED lights up constantly, and the green LED goes out (factory

default setting).

If interference occurs, all servos programmed to “Hold” remain at the last position detected by the

receiver as correct; this situation is maintained until such time as the receiver picks up a new, valid

control signal.

You can save your selection by holding the BIND / RANGE button pressed in for three to four se-

conds. When you release the button, both the red and green LEDs should light up constantly, and

the transmitter should not emit an audible signal: the transmitter now reverts to Control mode. If this

does not occur, repeat the procedure.

• Fail-Safe OFF: when you press the BIND / RANGE button, the transmitter beeps three times; the

green LED glows constantly, the red LED goes out.

You can save your selection by holding the BIND / RANGE button pressed in for three to four se-

conds. When you release the button, both the red and green LEDs should light up constantly, and

the transmitter should not emit an audible signal: the transmitter now reverts to Control mode. If this

does not occur, repeat the procedure.

• Standard mode (suitable for ﬁxed-wing model aircraft only): when you press the BIND / RAN-

GE button, the transmitter beeps four times; both LEDs are off.

In this mode the throttle servo (channel 1) moves to the Fail-Safe position, i.e. the position you have

programmed for a Fail-Safe situation, while all the other channels remain at “Hold”.

Move the throttle stick to the desired position, then hold the BIND / RANGE button pressed in for

three to four seconds. When you release the button, both the red and green LEDs should light up

constantly, and the transmitter should not emit an audible signal: the transmitter now reverts to

Control mode. If this does not occur, repeat the procedure.

2.4.Range warning

If the receiver signal in the down-link channel becomes too weak, the transmitter always generates an

audible range warning in the form of a beep emitted about once per second. Since the transmitter’s

output is much higher than that of the receiver, you will still maintain full control of the model, but in the

interests of safety you should ﬂy the model back towards you until the warning signal ceases again.

If the audible range warning signal does not cease when you reduce the distance, then the transmitter

or receiver low voltage or temperature warning is active! In this case you must land the model and cease

operations without delay.

2.5.Firmware update or SMART-BOX connection

The SMART-BOX is connected to the DATA socket on the back of the transmitter.

Getting Started Graupner HoTT 2.4 03

loaded ﬁrmware ﬁle ending in *.bin. If

everything is correct, the ﬁle will ap-

pear in the corresponding window.

The ﬁrmware ﬁles are encoded in product-speciﬁc form, i.e. if you accidentally select a ﬁle which does

not match the product (e.g. transmitter update ﬁle instead of receiver ﬁle), then the pop-up window “Pro-

duct code error” will appear, and you will not be able to start the update procedure (ﬁg. A).

06 Getting Started Graupner HoTT 2.4

Press the “Program” button in the software. Wait brieﬂy until

you see movement in the progress bar. This make take up to

ﬁve seconds, depending on the computer (ﬁg. B).

Receiver: press the SET button, and switch the receiver on

while you hold it pressed in.

After a few seconds the Status screen displays the message

“Found target device…”; you can now release the button, and

the ﬁrmware update process commences.

If the device is not recognised, if the pop-up window “Target de-

vice ID not found” appears, or if the process fails before 100%

is reached, you must restart the update procedure. Repeat all

the steps as described above.

The Status display and the Progress bar show the progress of

the ﬁrmware update. The update is completed when the popup

message “Download Process Complete” appears (ﬁg. C).

During the update process both red and green LEDs on the re-

ceiver glow constantly. When it is complete, the red LED starts

ﬂashing, the green goes out.

Switch your receiver off, and disconnect the adapter lead.

Caution: after completing an update process, you must in-

itialise the device before using it, i.e. reset it to the factory

default values.

Initialisation:

Press and hold the SET button on the receiver and switch it on, the red and green LED‘s are blinking.

After about three seconds the LED‘s expires, then only the red LED ﬂashes. Release now the SET

button, the initialization is complete.

Please note:

The initialisation procedure erases ALL the settings you have entered. Where necessary, you will need

to program your preferred settings again.

Any settings you have entered using the SMART-BOX are also lost when you initialise the recei-

ver. If you carry out a receiver ﬁrmware update, you will need to re-enter these settings.
