To stop the servo test, re-activate the input ﬁ eld as de-

scribed previously, then select STOP and conﬁ rm your

choice with the INC+DEC button.

ALARM VOLT (low receiver voltage warning)

ALARM VOLT monitors the receiver voltage. The

threshold can be set to any value within the range 3.0

to 6.0 Volt. If the voltage falls below the set alarm limit,

an audible signal (interval beeping, long / short) is

triggered, and “VOLT.E” ﬂ ashes at top right in all “RX …”

ALARM TEMP +/- (receiver temperature monitor)

These two options monitor the temperature of the

receiver: a lower limit value “ALARM TEMP-” (-20 ...

+10°C) and an upper limit value “ALARM TEMP+” (50 ...

80°C) can be programmed. If the temperature exceeds

the upper limit or falls below the lower one, an audible

signal (continuous beeping) is triggered, and “

TEMP.E”

appears at top r

ight in all receiver displays. The parame-

ter “R-TEM“ is also highlighted in the “RX DATAVIEW”

display.

Ensure that the receiver remains within the permitted

temperature range under all ﬂ ight conditions (ideally

between -10 and +50°C).

CH OUTPUT TYPE

At this point you can select how the receiver outputs are

to be addressed.

ONCE•

The receiver servo sockets are addressed in se-

quence; this is recommended for use with analogue

servos. At this setting the servos are automatically

operated at a frame rate of 20 ms (30 ms with the

twelve-channel receiver, Order No. 33512) - regard-

less of what is set or displayed in the “PERIOD” line

of the “RX SERVO” display.

SAME•

The receiver servo sockets are addressed in parallel

blocks of four, i. e. if you are using the GR-12 recei-

ver included in the set, channels 1 to 4 and channels

5 and 6 each receive their control signals simultane-

ously.

This is recommended for use with digital servos, and

especially where multiple servos are employed for

a single function (e. g. ailerons), to ensure that the

groups of servos run absolutely synchronously.

If you are using digital servos, we recommend that

you set 10 ms in the “PERIOD” line of the “RX SER-

VO” display so that you can exploit the fast response

of these servos. If you are using analogue servos, it

is essential to select “20 ms”.

If you choose the faster setting, please take par-

ticular care when selecting the receiver power

supply: since up to four servos can start moving si-

multaneously, the load on the battery is fairly severe,

so it must be a high-performance type.

SUMO (Sum signal OUT)•

A HoTT receiver conﬁ gured as SUMO constantly ge-

nerates what is known as a sum signal from the con-

trol signals of all its control channels. This signal is

present, for example, at servo socket 6 of the GR-12

receiver.

The maximum sum signal can be set independent

from the receiver up to 16 channels, e.g. a 6-channel

receiver can be programmed on SUMO 12 and trans-

mits all 12 channels on the output.

After SUMO is selected and saved with

INC+DEC,

the in

verse marker jumps forward to the channel

number, here 06:

Pressing INC or DEC selects the number of chan-

nels to be tr

ansmitted in the sum signal. INC+DEC

saves the settings.

The receiver outputs are addressed in sequence at a

frame rate of 20 ms (30 ms with the GR-24 receiver,

Order No. 33512), even if you have set 10 ms in the

“PERIOD” line of the “RX SERVO” screen page.

Although primarily intended for “satellite mode” with

two HoTT receivers, as described below, the sum si-

gnal generated by the receiver deﬁ ned as SUMO can

Data socket

For connecting the optional Smart-Box, Order No. 33700.

The Smart Box allows many other HoTT functions such

as Servo curve, servo travel, cycle time or channel map-

ping and HoTT telemetry - see the section „telemetry“

on page 113.

For more details about the Smart-Box please refer to the

main Graupner FS catalogue, or refer to that product on

the Internet at www.graupner.de.

This socket can be used also to connect the transmitter

to a PC running Windows XP, Vista or 7 using the optio-

nal USB adapter, Order No. 7168.6 and the connecting

lead, Order No. 7168.6A.

The software required at the PC, including a suitable

USB driver, can be found in the Download section for

the corresponding product at www.graupner.de.

Once you have installed the software required, you can

also update the transmitter via this connection.
