Preliminary remarks about the GR-24 receiver
Receiver system
The
mx-20 HoTT remote control set includes a type
GR-24, 2.4 GHz bidirectional receiver for connecting up
to 12 servos.
After switching on this HoTT receiver, should "its"
transmitter not be within range or switched off, then the
receiver's red LED will illuminate continuously for about
1 s then begin to blink slowly. This indicates the receiver
has not (yet) established a link to a Graupner HoTT
transmitter. If a link has been established, the green
LED will illuminate continuously and the red LED will
extinguish.
In order to establish a link to the transmitter, the
Graupner HoTT receiver must fi rst be "bound" to
"its" particular model memory in "its" Graupner HoTT
transmitter. This procedure is known as "binding".
This "binding" linkage is only necessary once for each
receiver/model memory combination. Refer to pages
69 or 74. The "binding" procedure has been done at
the factory for model memory 1 of the units delivered
together as a set so this "binding" procedure will only
be necessary to link additional receivers or if a memory
location change becomes necessary (and – e. g. after a
change of transmitter – can be repeated anytime).

On-board voltage display
The current voltage of the receiver's power supply will
be shown in the right side of the transmitter's screen
if a telemetry link exists between the receiver and
transmitter.

Temperature warning
Should the receiver's temperature sink below an
adjustable threshold (default value -10 °C) or rise
above an adjustable threshold (default value +55 °C),
Should the receiver's temperature sink below an
adjustable threshold (default value -10 °C) or rise
above an adjustable threshold (default value +55 °C),
an acoustic warning will be issued by the transmitter in
the form of a uniform beep of about 1 s duration. The
aforementioned threshold limits are stored and adjusted
in the receiver.

Servo connections and polarity
Graupner HoTT receiver servo connections are
numbered. The connectors used are keyed against
polarity reversal. Pay attention to the small side profi les
when plugging in these connectors. Never use force.
The two outer connections, having designations "11+B-"
and "12+B-" are intended for the battery connections.
These two connections plus the servo's respective
connections can be combined into a single connector at
each end by way of a V or Y cable, Order No. 3936.11.
Do not reverse the polarity of this connection.
Reversed polarity could destroy the receiver and
devices attached to it.
The supply voltage is bussed across (i.e. common
for) all numbered connections. The function of every
individual channel is determined by the transmitter
used, not by the receiver. It is not only the throttle servo
connection which is different for every manufacturer and
model type. For example, in Graupner remote control
systems the throttle servo is on channel 1 for winged
aircraft and on channel 6 for helicopter models.

again.
If a receiver reset is done while the transmitter is
switched off or on a receiver which is not bound, the
receiver's LED will slowly blink red for about 2 or
3 seconds and then a binding procedure can be started
right away on the transmitter.
If reset is done on a bound receiver and the
corresponding model memory is active in the powered
on transmitter, the LED will illuminate in green after
a brief period as an indication that your transmitter/
receiver system is again ready for operation.
