01 33700 SMART-BOX - Graupner HoTT 2.4

THANK YOU

for purchasing the Graupner HoTT SMART-BOX.

Intended use

If you do not have the Graupner HoTT 2.4 radio system this product will not work. This product is not com-

patible with any other 2.4GHz radio system.

Please read through this entire manual before you attempt the installation and usage of your Graupner

HoTT SMART-BOX!

These operating instructions are part of this product. They contains important notes to the operation and

handling. Please take this into consideration when you pass on the product to third parties. Neglect of the

operating instructions and the safety instructions lead to expiring the warranty.

Graupner constantly work on the advancement of all remote control systems; changes of the scope of deli-

very in form, technology and equipment we must reserve ourselves therefore. Please have understanding

for the fact that from data and illustrations of this operating instructions no requirements can be derived.

Please keep these instructions for further reference!

DESCRIPTION1.

For the Graupner HoTT 2.4-GHz transmission system, the SMART-BOX is display and programming device

in one. Whether telemetry data are displayed in real time or settings have to be made in your HoTT sys-

tem, the generous display with 8 x 20 characters facilitates easy handling. Four switches are available for

operation. An integrated buzzer to sound acoustic signals and warning tones makes the BOX even more

convenient to use.

Informations available - Setup:

Transmitter: Operating voltage, Minimum Voltage Warning, Country setting and Range test

Receiver: RX Operating voltage, signal strenght, receiver temperature, servo reverse, Trim position, ser-

vo travel, failsafe, Channel Mapping, free mixer, model mix, servo test and sum signal

Telemetry: depending on connected sensor

Altitude, min. Altitude, max.Altitude, negative/positive difference/s, negative/positive

difference/3s, battery voltage (total - single cell), Min./Max. voltage, Min./Max. cell voltage,

Temperature (optional Sensor 1/Sensor 2), Min./Max. Temperature, fuel level, Min. fuel level,

RPM, Min./ Max. RPM

Since the SMART-BOX can be updated via the USB connection, you always have the latest software and

can utilize future functions or languages. Firmware updates for the SMART-BOX can be transferred via

the DATA or telemetry interface in conjunction with a PC running Windows XP, Vista or 7. For this you also

require the USB interface, Order No. 7168.6, and the adapter lead, Order No. 7168.6A, which are available

separately.

The programs and ﬁles required for this are available from www.graupner.de in the Download area for the

corresponding products.

Please note:

All settings (e.g. fail-safe, servo reverse, servo travel etc.) which you carry out using the SMART-BOX are

stored exclusively in the receiver, i.e. the altered settings are not displayed in the transmitter menu. This me-

ans that you should either carry out the programming using the transmitter only, or using the SMART-BOX

only, otherwise conﬂicts may occur. If you have entered all the previously implemented parameter settings

using the SMART-BOX, and then makes changes to some aspects using the transmitter, the SMART-BOX

settings will be overwritten (fail-safe settings) or modiﬁed, and this can lead to problems in use.

Example: you use the SMART-BOX to program elevator servo travel to 80%, and this will be displayed

correctly on the SMART-BOX screen in the RX SERVO menu; however, it will not be displayed in the trans-

mitter menu. During the next ﬂying session you may wish to reduce the same setting in the transmitter menu

itself, perhaps because you have left the Smartbox at home. You will ﬁnd that the value for this servo in the

33700 SMART-BOX - Graupner HoTT 2.4 02

transmitter menu is still 100%, and if you now enter, say, 90%, in order to reduce the travel by a further 10%,

the SMART-BOX will not be aware of this change. The net result is that you now have two different displays

for the same value, but neither is actually correct as the servo travel is affected by both settings, which need

to be combined in order to determine the actual servo travel. Further examples would be the servo reverse

function or the transmitter control assignment to individual receiver channels. It is easy to see that this could

be confusing in day-to-day operations, and should therefore be avoided.

For this reason you should always - wherever possible - continue using the SMART-BOX to maintain pro-

grammed values. If you neglect to do this, you MUST reset all the SMART-BOX settings by re-initialising

your transmitter and your receiver(s).

Transmitter: To initialise the system, i.e. to reset it to the factory default settings, locate the BIND / RANGE

button on the back of the transmitter, hold it pressed in while you switch the transmitter on, then release the

BIND / RANGE button again.

Receiver: To initialise the system, i.e. to reset it to the factory default settings, locate the BIND / RANGE

button on the back of the transmitter, hold it pressed in while you switch the transmitter on, then release the

BIND / RANGE button again. Now immediately press and hold the SET button on the receiver, switch it on,

and release the SET button again. After about two or three seconds the green LED on the receiver lights up

to conﬁrm that your radio control system has been re-initialised.

Please note:

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

program your preferred settings on the transmitter or SMART-BOX again (see also 3.1. and 3.2.3).

Please refer to the appropriate section in your RC system instructions for the procedure.

2. STARTING UP

Install the SMART-BOX at the mounting bracket of the transmitter as shown in the

ﬁgure. Connect the box then the 3-pin lead to the transmitter. Put one end of the

cable into the DATA jack on the transmitter and the other into the jack on the right

side of the SMART-BOX. The connector system is polarised, look for the small

camfer on the edges. Never use force - the plug should engage easily and fully. The

sockets are labeled accordingly: black wire (-), red wire (+) and orange wire (S).

3. OPERATION

The SMART-BOX is operated by the four buttons on the top. Switch with the ESC and ENTER keys between

the different displays. With the DEC and INC buttons you can select the parameters in the display (INC

moves the cursor down, DEC up).

Switch on the transmitter. On the startup screen appears SETTING AND DATA VIEW / MODEL SELECT /

EXTERNAL MONITOR. Move the arrow cursor with the INC or DEC buttons on SETTING AND DATA VIEW

and then press ENTER to display the parameters of the transmitter, receiver and telemetry sensors and /

or program it (not available for the new HoTT Transmitters - see EXTERNAL MONITOR), or select MODEL

SELECT / EXTERNAL DATA VIEW to display the telemetry data graphically (see point 4).

In MODEL SELECT / EXTERNAL MONITOR display no settings are possible.

From HoTT Firmware version V4 on multiple sensors not only can be connected via a Y-cable and displayed

by the graphical mode MODEL SELECT, but also for example the alarm thresholds can be programmed in

the menu SETTING AND DATA VIEW. To do this, the sensor to be programmed must be selected in a ﬁrst

step.

Switch on the transmitter. On the startup screen appears SETTING AND DATA VIEW / MODEL SELECT /

EXTERNAL MONITOR. Move the arrow cursor with the INC or DEC buttons on SETTING AND DATAVIEW

and then press ENTER to go to the programming display.

SETTING AND DATAVIEW: up to ﬁrmware version V3 choose RECEIVE+OLD SENSOR - regardless of

which sensor is actually connected - from ﬁrmware V4 go to the menu line below and select the sensor to

be programmed:

RECEIVE+GENERAL/GAS = Receiver+GENERAL MODULE #33610 or #33611

RECEIVE+ELECTRONIC = Receiver+ELECTRIC AIR-MODUL #33620

RECEIVE+VARIO = Receiver+VARIO MODUL #33601

RECEIVE+GPS = Receiver+GPS #33600

The transmitter and receiver data is displayed in each menu.

The various programming options of the HoTT telemetry modules are described in detail in the instructions.

Note: when using ﬁrmware V3 and multiple sensors are connected via a Y-cable to the receiver, all sensores

that are not be programmed must be disconnected prior to the selection of the menu RECEIVE+OLD SEN-

SORS. Only one sensor may be connected! See also point 4 - telemetry display.

Unlike SETTING AND DATA VIEW, the telemetry data from MODEL SELECT or EXTERNAL MONITOR can

only be viewed but not be programmed. However, the data is represented in graphic form, and this makes it

the preferable option when actually operating a model, as it is easier and quicker to read and access.

Parameters which have different options in the Settings column of the table can be adjusted using the

SMART-BOX. If there are no options, the screen simply displays the parameter data.

If you wish to carry out an adjustment, you must use the INC or DEC buttons above the screen to select

the desired parameter (e.g. ALARM VOLT) by moving the arrow cursor (INC moves the cursor down, DEC

moves it up). Simultaneously pressing the INC and DEC buttons switches the parameter to be adjusted to

inverse video (white on black); this indicates that it can be programmed: pressing the INC button at this point

increases the value, pressing the DEC button reduces the value. When the adjustment is complete, save the

selected setting by pressing the INC and DEC buttons simultaneously; the dark background now disappears

in order to conﬁrm this action.

Transmitter low-voltage warning (ALARM VOLT): you can adjust the low voltage threshold at which the

alarm (continuous beeping) is triggered; the available range is 4 - 15 V.

When the alarm is triggered, “VOLT-E” ﬂashes at top right in the SMART-BOX transmitter display, and the

parameters ACTION VOLT and ALARM VOLT are displayed in inverse form.

Note: the transmitter has an integral low-voltage warning (beep) which is triggered when the transmitter

voltage falls to 9.4 V, regardless of the value set using the SMART-BOX.

Country selection (COUNTRY): The Country setting is present in order to cater for various directives (FCC,

ETSI, IC etc.). The HoTT 2.4 radio system features a restricted frequency band for France. If you wish to use

the RC system in France, the country setting on the transmitter must be set to “France” mode, as described.

It is essential not to use the Universal/EUROPE mode. Factory setting is GENERAL.

Range checking (RANGE TEST):

switches the range test on or off, the remaining time is displayed. The display also works if the range check

is started with the BIND / RANGE button on the transmitter.

Multichannel 1 / 2 (MULTIC 1 / 2: Multi-channel function for the use with the Nautic-Expert-Module order

no. 4108. Up to 2 multi-channel channels can be used, the appropriate channels must be set in the display

under MultiC. If no Nautic module is used, set MULTIC to 00.

Note: only suitable for digital servos! The cycle time (PERIOD) must be set to 10 msec, the channel se-

quence (CH OUTPUT TYPE) to SAME so that the function is activated!

If you wish to switch to the receiver data display, press the ENTER button repeatedly until RX DATAVIEW

appears on the screen.

Please note: menus 3.2.1 to 3.2.6 can only be selected when the receiver

is switched on. When you switch the receiver on, it may take a few se-

conds before the receiver display becomes active and can be selected: >

symbol appears at the top right corner of the transmitter display (TX).

There may be a slight delay in the screen’s response to inputs using the

top buttons, since all the settings are transmitted directly to the receiver

by wireless means.

In the receiver data view display settings can not be made.

Signal quallity (S-QUA): shows the signal quality in %

Receive performance (S-dBm): the receive performance is sent “live” to the SMART-BOX via the receiver’s

downlink channel. Note: the receive performance is shown as a negative value, i.e. a value approaching

zero is the maximum (= best reception); the lower the value falls, the worse the receive performance.

This value is particularly important during the range-check procedure carried out before ﬂying the model.

Please read the corresponding section in the RC system instructions relating to range-checking.

Carry out a range-check before every ﬂight, simulating all servo movements which will occur in ﬂight: the

range must be at least 50 m on the ground when the transmitter is set to range-check mode; to guarantee

safe ﬂying, the value displayed under S-dBm in the DATAVIEW display should be at least -80 dBm. If the

value is lower (e.g. -85 dBm) you should not even consider ﬂying your model: check the receiver installation

and the power supply systems in your model and radio control system.

When operating your model this value should not fall below -90 dBm. If it does, you should reduce the dis-

tance between yourself and the model. However, under normal circumstances the audible range warning

(see below) will be triggered before the value falls to this level, in order to ensure safe operations.

Signal strenght (S-STR): indicates the signal strenght in %.

An audible range warning (continuous beeping at one-second intervals) is always emitted as soon as the

receiver signal in the downlink channel falls to the pre-set threshold. Since the transmitter has a much higher

transmitting power than the receiver, it is still possible to operate the model safely, but in the interests of

security you should always reduce the distance to the model until the audible warning stops.

Receiver temperature (R-TEMP): it is important that the temperature of your receiver always stays within

the approved range under all ﬂight conditions (ideally between 10 and 55°C; please refer to your RC system

instructions).

The limit values for receiver temperature which trigger a warning can be set in the RX SERVO TEST display

under ALARM TEMP+ (50 – 80°C) and ALARM TEMP- (-20 – +10°C).

If the receiver temperature rises above the maximum value or falls below the minimum, the unit generates an

audible warning (continuous beeping). At the same time all the Smartbox receiver displays show a ﬂashing

“TEMP.E” at top right, and the parameter R-TEM is shown in inverse form in the receiver data display (RX

DATAVIEW).

Data packets (L PACK TIME): indicates the duration of signal loss of the longest data packet during trans-

mission from transmitter to receiver, stated in msec. In practice this equates to the longest period which the

RC system has spent in fail-safe mode.

Operating voltage (R-VOLT): it is essential to monitor the operating voltage of the receiver constantly. If it

is too low, you must never launch your model or continue ﬂying it.

The receiver low voltage warning can be adjusted in the RX SERVO TEST display under ALARM VOLT; the

available range is 3.0 to 6.0 Volt. If battery voltage falls to the threshold level, an audible signal (continuous

beeping) is emitted, and “VOLT.E” ﬂashes at top right in all the Smartbox receiver displays. At the same time

the parameter R-VOLT is shown in inverse form in the receiver data display (RX DATAVIEW).

Minimum operating voltage (L.R-VOLT): displays the lowest receiver operating voltage since the last time

the receiver was switched on. If this voltage differs signiﬁcantly from the actual operating voltage R-VOLT, it

is likely that the servos are placing an excessive load on the receiver battery, resulting in voltage collapses.

If this should occur, you should consider ﬁtting a larger or more robust receiver battery in order to obtain

maximum operating security.

Telemetry sensor 1 / 2 (SENSOR 1 / SENSOR 2): if these optional sensors are connected, their data

(Voltage / Volt and temperature / °C) is displayed live on the screen.

See also Chapter 4 - Telemetry displays.

3.2.2 Servo data (RX SERVO)

To switch to the servo data display, press the ENTER button repeatedly until RX SERVO appears on the

screen.

Channel select (OUTPUT CH): here you select the desired channel; the remainder of the settings in this

display only affect the channel which you select at this point.

Servo reverse (REVERSE): sests the direction of rotation of the connected servo

Normal: REVERSE OFF

Reverse: REVERSE ON

Servo centre (CENTER): The “CENTRE” line displays the current pulse width in μs of the control channel

selected in the “OUTPUT CH” line. The displayed value varies according to the current position of the

transmitter control which affects this control channel, and also its trim position. A pulse width of 1500 μs

corresponds to the standard centre position, and therefore the usual servo centre setting.

To change this value, select the “CENTRE” line and touch the INC + DEC buttons simultanously. Move the

corresponding transmitter control to the desired position, and touch the INC + DEC buttons again to store the

current transmitter control position. This position is now stored as the new neutral position.

Trim position (TRIM): The purpose of the “TRIM” line is to provide ﬁne adjustment of the neutral position of

a servo connected to the control channel selected in the “OUTPUT CH” line. Adjustments are made in 1 μs

increments using the INC or DEC buttons. The value in the “CENTRE” line can be adjusted over the range

+/- 120 μs around the TRIM value set here.

Cycle time (PERIOD): at this point it is possible to deﬁne the speed of the servos’ response to movements

of the transmitter controls. This adjustment applies to all channels.

Note: if you are using analogue servos, you must set a value of 20 msec. If you are using digital servos

exclusively, 10 msec should be selected.

Output channel select (OUTPUT CH): this is where you select the desired channel; the remainder of the

fail-safe settings only affect the channel selected at this point.

Input channel select (INPUT CH): channel mapping function

The control functions can be distributed over several receivers in any sequence; alternatively multiple recei-

ver outputs can be assigned to the same control function. For example, this is useful if your aircraft features

two servos acting on each aileron instead of only one.

The SMART-BOX can be used to manage a maximum of sixteen transmitter channels. At this point you can

deﬁne how the transmitter channels (INPUT) are assigned to the channels (OUTPUT) of the receiver(s).

If your model is ﬁtted with multiple receivers, the Master receiver is the last receiver to be bound. However,

in subsequent operations only the receiver which was bound last is able to make a telemetry connection

to the transmitter. On the other hand, this also means that only the last bound receiver can be addressed

using the Telemetry menu.

Fail-safe mode (MODE): this function is used to select the fail-safe mode for the channel you have selected.

You can select either a programmed fail-safe position (Fail Safe), hold-mode for the last position (HOLD)

or OFF.

But CAUTION: if the control signal is absent, analogue servos and many digital servos offer no resistance

to the forces acting on the control surfaces, with the result that the model’s control surface positions are

more or less quickly lost.

Please read the corresponding chapter in the RC system instructions on this subject.

F.S.Pos. (Fail-Safe position):

For each OUTPUT CH (receiver servo socket) activate (highlight) the value ﬁeld by brieﬂy pressing the INC

+ DEC simutanously, then use the INC or DEC buttons in the “F.S.POS.” line to set the servo position which

the servo is to take up in “FAIL-SAFE” mode if interference should occur. The setting can be entered in

increments of 10 μs. Default setting: 1500 μs (servo centre).

Important note:

The “F.S.POS.” function is also signiﬁcant if the receiver is switched on, but is (not yet) receiving a valid

signal; this applies to all three modes “OFF”, “HOLD” and “FAILSAFE”: The servo immediately runs to the

Fail-Safe position previously set in the “Position” line. This can be exploited, for example, to prevent the

operation of a retractable undercarriage or similar function if the receiver is switched on accidentally. How-

ever, during normal model operations the corresponding servo behaves in accordance with the set “MODE”

if interference should strike.

Fail-safe response time (DELAY): this point is used to select the delay time after which the servos run to

their selected position if interference affects the radio signal. This value is applied to all channels.

FAIL SAFE ALL (global fail-safe setting): This sub-menu can be used to deﬁne the Fail-Safe position of

the servos simply by “pressing a button”; and is simple to use: Move to the “FAIL-SAFE ALL” line and press

the INC + DEC buttons simultanously to activate the value ﬁeld; “NO” is highlighted (black background). Now

set the parameter to “SAVE” using the INC or DEC button. Use the transmitter controls to move all the servos

which you have assigned - or intend to assign later - in the “MODE - FAIL-SAFE” line, to the desired fail-safe

positions. In the extreme bottom line “Position” displays the current position of the transmitter control for the

channel you have just set.

After touching the INC + DEC buttons once more, the display reverts from “SAVE” to “NO”. This indicates

that the position of all the servos affected by the procedure have now been stored, and have also been

adopted in the “F.S.Pos.” line. At the same time the position for the current OUTPUT CH (servo socket) is

immediately displayed on the screen.

Switch the transmitter off, and check the Fail-Safe positions by observing the servo movements.

Fail-safe position (POSITION): displays the Fail-Safe position for the channel set under OUTPUT CH.

“Fail-Safe” in combination with “channel mapping”

It is clearly desirable that mapped servos - i.e. servos which are controlled by a common control channel (IN-

PUT CH) - should respond in the same way when interference occurs, so the corresponding settings of the

INPUT CH determine the behaviour of mapped servos.

For example, if receiver servo sockets 6, 7 and 8 are mapped together, i.e. if the same control channel “04”

is assigned to OUTPUT CH (servo sockets) 06, 07 and 08 then INPUT CH 04 determines the Fail-Safe

behaviour of the three servos connected to control channel 4, regardless of the individual settings of the

OUTPUT CH for INPUT CH 04. This also applies, for example, if it is mapped in turn to INPUT CH 01.

In this case servo socket 04 would respond in accordance with the Fail-Safe settings for CH 01. In contrast,

the response or delay time set in the “DELAY” line always applies uniformly to all channels which are set

to “FAIL-SAFE”.

CAUTION: if the receiver is switched on and you call up the fail-safe function again using the programming

button on the transmitter, any settings previously programmed in the FAIL SAFE display using the SMART-
