Installing The Receiver - GRAUPNER mz-24 Pro Programming Manual

Installing the receiver

Installing the Receiver
The following procedure is the same across all
Graupner receiver systems.
Install the receiver behind a strong bulkhead where it
is protected against dust or splash water. Make sure
that it is not excessively airtight to prevent it from
overheating during operation.
The receiver should not directly touch the fuselage or
chassis since they can directly transmit motor vibra-
tion or impact from landing. When installing the receiv-
er in a model with a gas motor, all of the parts must be
protected to prevent exhaust or oil from penetrating.
This holds true in particular for ON/OFF switches that
are installed on model shells.
The receiver's servo and power supply connecting
cables should remain loose. The receiving antennas
should be at least 2 inches (5 cm) from all large met-
al parts or wires that do not directly originate from
the receiver. This includes carbon fiber parts, servos,
electric motors, fuel pumps, all types of cables, all
steel parts, etc.
Install the receiver away from all other installed parts
at an easily accessible location in the model. Servo
cables should not be wound around or run next to
antennas because radio transmission interference will
occur.
Note that the cables can shift during flight accelera-
tion. Make sure that the cables cannot slip and move
directly adjacent to antennas and interfere with recep-
tion.
Installing the Receiver Antennas
With a single antenna, orientation is not crucial.
With dual antennas, the active end of the second an-
tenna should be at a 90° angle from the end of the first
antenna, and the distance between the active ends
should be a minimum of 5 inches (125mm).
For carbon fiber fuselages, the ends of the antennas
should extend from the fuselage about 2 inches (125
mm). If needed, replace the standard HoTT receiver
antennas with longer 300 mm or 450 mm antennas
(No. 33500.2 or 33500.3).
Servo Connections and Polarity
Graupner-HoTT receiver servo connections are num-
bered; the supply voltage runs through the numbered
connections. The polarity of the plug-in system cannot
be reversed. When inserting the plug, note the small
bevels on the side. Insert gently and do not use force.
Attention
Do not reverse connection polarity. This can de-
stroy the receiver and connected devices.
Notice
In compact receivers, such as GR-12L HoTT,
the outputs 1 through 6 are reversed 180° from
that of the bigger receivers. Pay close attention
while connecting any plug to the receiver. If applicable,
use a V or Y cable (No. 3936.11).
Channel Mapping
The function of each channel is determined by the
transmitter and not the receiver. Change the channel
mapping settings directly through the BASE submenu
Telemetry (page 104), or indirectly through the BASE
submenu Out.Swap (page 96).
