Installing the receiver
The receiver must be protected against dust, exhaust gases, splash
water, rests of oil etc. in the model. When you install your receiver,
make sure that it is not excessively airtight to prevent it from over-
heating during operation.
Servo cables may not be wound around antenna or run next to it.
Make sure that the cables cannot shift to lie directly adjacent to
antenna during flight.
In the case of carbon fibre chassis, at least the last 35 mm of the
antennas shall be routed outside.
Connection assignment
The connection cables to be connected to the receiver must be
plugged with the black or brown cable outwards into the connector
strip of the receiver, see illustrations. The polarity of the plug-in sys-
tem cannot be reversed. Do not apply force. Never connect the con-
necting cables "across", over 3 connections, to the receiver. This
immediately leads to a short circuit of the power supply; the destruc-
tion of any connected components as well as the immediate loss of
all warranty claims.
Receiver GR-4 HoTT
The GR-4 HoTT receiver has a total of 4 slots:
1 Steering servo
2 Throttle servo or ESC
B/T HoTT telemetry sensors / Power supply / Updates
T/V Temperature / voltage sensor
Note
The GR-4 HoTT receiver is compatible with all Graupner HoTT trans-
mitters.
Receiver GR-8 HoTT V2
The
GR-8 HoTT V2
receiver has a total of 5 slots:
1 Steering servo
2 Throttle servo or ESC
3 free or battery or special function so as firmware updates
4 free or battery or special function
T/V Temperature / voltage sensor
Note
the GR-8 HoTT V2 receiver is actually only compatible with the
Graupner transmitters X-8E and X-8N .

Slots 1 and 2 or 1 to 4
The steering servo is to be connected to port 1 and the throttle servo
of combustion engine or the speed controller of electric models to
port 2.
Ports 3 and 4 of the
GR-8 HoTT V2 are freely assignable control chan-
nels for special functions.
Both on the transmitter side and via the telemetry menu, see below,
each of the four ports of the GR-8 HoTT V2 receiver can be arbitrarily
switched to one of a total of six connection protocols, extending the
range of connectable RC components from standard servo to ultra-
short pulse digital controlled speed controller.
The power supply of the receiver as well as the RC components can
be connected to it over each of these four connections.
Port "B/T"
Note
Only available with the GR-4 HoTT receiver.
This socket is suitable for connecting the receiver power supply as
well as for connecting HoTT telemetry sensors and for updating the
receiver.
The voltage applied to this socket operating voltage of the receiving
system is monitored. As soon as the warning threshold set in the line
"AL RX-V" of the receiver menu "RX SETUP" is exceeded, the trans-
mitter emits an acoustic alarm.
Port "T/V"
This socket is only suitable for connection of the optional external
voltage and temperature sensor with the order no. S8362 and the
voltage measurement described below.
If a sensor is connected, the warning threshold set in the lines "AL
EX-V" or "AL EX-T" of the receiver menu "RX SETUP" becomes effec-
tive. As soon as this value is exceeded, the transmitter issues an
alarm.
Attention
This socket is neither suitable for connecting a receiver power sup-
ply nor for the direct connection of a drive battery! As a result, the
receiver would be destroyed immediately. The socket is only suit-
able for connecting the mentioned sensors or for measuring the
voltage of a battery according to the following scheme:
