Connections
Connect the speed controllers or Servos to the row of sock-
ets on one end of the receiver. The connectors are polarised:
note the small
chamfers on one side. Never use force - the connectors should
engage easily. The polarity is also printed on the receiver; the
negative wire (-) is brown, the positive (+) red and the signal
orange. The servo sockets of
Graupner HoTT
2.4 receivers are
numbered sequentially. The socket for channel 8 (K6 in GR
18) can also be programmed to deliver a (digital) sum signal
(see next section).
Power supply
The receiver does not feature specific sockets for connect-
ing the battery. We recommend that you connect the power
supply to the socket(s) close to the servos already connected
to the receiver. If you wish to connect multiple separate bat-
teries, the batteries must be of the same nominal voltage and
capacity. Never connect batteries of different type, or packs
of greatly differing states of charge, as this can cause effects
similar to a short-circuit. If you encounter this problem, we
recommend the use of a voltage stabiliser unit (e.g. PRX-5A
receiver power supply, Order No. 4136) between the batteries
and the receiver.
Telemetry or channel (T/9) socket
The optional telemetry sensors are connected to the socket
marked “T” (T/9)- Telemetry. In addition, the update is per-
formed on this socket (see point 5). The socket can be used
optionally for K9. (see next section)
Receiver setting menu
The receiver set-up menu appears in the “Telemetry” menu
under SETTINGS / DISPLAYS; alternatively - if you are using a
SMART-BOX - under SETTING & DATAVIEW. The method of
accessing this menu is described in the operating instructions
supplied with your transmitter or the Smart-Box.
Low-voltage warning (ALARM VOLT)
If the receiver voltage falls below the set value, a low-voltage
warning is generated by the transmitter’s RF module in the
form of the “general alarm tone”: a regular beeping at a rate of
about one per second; alternatively the speech output mes-
sage “Receiver voltage”.
Temperature warning (ALARM TEMP)
If the receiver temperature exceeds the set temperature thresh-
old, a warning is generated by the transmitter’s RF module in
the form of the “general alarm tone”: a regular beeping at a
rate of about one per second; alternatively the speech output
message “Receiver temperature”.
