Additional receiver functions
The GR-12L and GR-12+3G receivers included in the set
have additional functions that can only be set when used
in combination with a telemetry-enabled transmitter.
When the receivers have been programmed to work with
a telemetry-enabled transmitter, they can also be used
with the functions programmed in the MXS-8 and MXS-12
(e.g. mixer, servo settings).
The transmitter emits audible warnings of receiver tempe-
rature and voltage levels.
Warnings from other sensors (e.g. Vario) are not emitted.
With the MXS-8 and MXS-12 transmitters, it is not possi-
ble to use the SMART-BOX or to program the receivers.
Detailed instructions for programming the receivers can
be found on the Internet at www.graupner.de under the
particular product.
Updating receiver firmware
Receiver firmware updates are made by way of the
telemetry connector of the receiver (channel 5) using a
PC running under Windows XP, Vista, 7 or 8. The optional
USB interface order no. 7168.6 and the optional adapter
cable order no. 7168.S are additionally required. The
programs, files and instructions additionally required can
be found at www.graupner.de under the downloads for the
particular product.
Note:
Refer to the detailed updating instructions
for information on the updating procedure.
This information is available on our websi-
te under Update-Revisions-History. Please
download the 'Firmware Upgrade Studio' kit
for this purpose. It contains the update pro-
gram and the instructions.

Explanation of terms

Control function, control, control channel, mixer
To help you in using this
manual, a number of the terms used repeatedly throug-
hout this manual are explained below.
Control function
A 'control function' is a signal for a given control action;
this holds in general, regardless of the signal path in
the transmitter. Examples for a winged aircraft include
throttle, ruder or aileron, and for a helicopter, pitch, roll or
crow. A control function signal can be applied directly via
a single control channel or through a mixer via several
control channels. A typical example of multiple control
channels is separately operated aileron servos or a V-tail
unit. The control function explicitly takes into account
the influence of the control's mechanical travel on the
respective servo.
Control
'Controls' include all operating elements on the transmit-
ter which are directly activated by the pilot to operate the
servos, speed controllers etc. connected to the receiver.
This includes:
• Both joysticks for the control functions 1 through 4,
whereas these control functions can be switched, e.g.
to set throttle at left or right, by modifying the joysticks
(refer to the section "Converting the joysticks"). The
joystick function for throttle/airbrake control is also
often referred to as the C1 control (channel 1).
• The proportional operating elements produce a direct
effect on servos which is commensurate with the
control's position whereas switch modules can only
adjust the position by two or three steps.
Control channel
The term 'control channel' refers to a signal from the point
at which it contains all control information necessary for
a particular servo, regardless of whether the information
is obtained directly from the physical control or indirectly
by way of a mixer. This signal is then only affected by
settings made in the »Servo adjustment« menu before
it leaves the transmitter's RF module. Arriving at the
receiver, this signal may still be modified by settings
made in the telemetry menu before finally being applied
to the respective servo as a control quantity.
