MIXED CONNECTION
The servo signals at the normal servo output (channel 1...8) and at the
S-BUS output are simultaneously available. To replace a V-lead, for ex-
ample, one servo can be connected to the normal output and the second
servo to the S-BUS output.
Note:
The maximum number of S-BUS channels is 16 + 2. However, only the
same number of channels are available for the control as the transmitter
has (currently 8 + 2 or 12 + 2).
Important:
A battery connected directly to the receiver can make available current at
2.5 A permanently and 5 A short-term. A second battery connection should
be provided on the connector strip of the receiver for higher power require-
ments. The current-carrying capacity then increases to 5 A permanent, 10
A short-term. We recommend the use of the battery switch PSS 2018 No.
F1660 for higher currents!
Please refer to the main catalogue for other S-BUS accessories.
Recommended accessories:
The S-BUS PWM adapter No. F1695 makes it possible to use the new
S-BUS system in existing models and servos. Adatper for connecting 3
standard servos to the S-BUS. Converts the signal from S-BUS to PWM
for each output separately. The same or different channel numbers can be
allocated to the outputs. The channel numbers are allocated either by using
the PC-Link software on a PC or independent of the PC with the handy S-
BUS programmer SBC-1.
Failsafe/Hold Mode Selection (Only TM-8 Module)
It is possible to select between two alternative modes if there is no radio
link between the transmitter and receiver.
1. NOR (Normal) or Hold mode.
The last intact pulses are buffered in the transmitter and sent to the servos
in the case of fault. They are retained until further intact signals are recei-
ved from the transmitter
.
2. (F/S) Failsafe position.
The gas servo assumes a position (which is also stored in the receiver)
preprogrammed via the TM-8 module.
Failsafe position setting for the gas channel (3).
• Set transducer for the gas channel to the required F/S position, press and
hold the F/S Range button on the module and switch on the transmitter.
• Check that the green LED on the TM-8 module is flashing, indicating that
RF is being emitted and F/S transmission is switched on.
• Switch on receiver power supply
• Press and hold the Easy Link button (ID set) on the receiver for at least 1
second and then release in order to store the failsafe position.
• The green LED lighting indicates that pairing and F/S position transmis-
sion have been completed successfully.
• Switch of transmitter and check whether the gas servo assumes the
required F/S position.
•Switching on the transmitter with the F/S Range button held will switch to
Hold mode or switch alternately between F/S and Hold mode.
To change the F/S position, first switch to Hold mode followed by F/S and
then repeat the pairing and F/S position storing procedure.
NOTE:
To prevent the receiver from being paired to the „wrong" transmitter, make
sure there is no other FASST system in the immediate vicinity during the
pairing or F/S setting procedure.
Do not set the F/S gas value too low otherwise the motor may stall.
IMPORTANT:
On helicopter models, the F/S gas value should not be set below 80% in
order to avoid the model falling suddenly in a failsafe situation. It may be
necessary to set Normal (Hold) mode for certain models.
TIPS ON INSTALLING 2.4 GHZ FASST RECEIVERS AND AERIALS
Over the years, every RC user has gained his/her experience when it
comes to installing and using RC components. 2.4 GHz technology
signals a new era offering wide-ranging benefits. This means there
are a few differences in the 2.4 GHz system that need to be taken
into account, making it necessary to install and use RC compon-
ents accordingly.
One of the most common mistakes is to follow the previous practice
of wrapping the receiver in foam or insert it in a foam tube in order
to protect it from vibration. This is no longer necessary with the 2.4
GHz FASST receivers as they no longer have a ceramic filter and
are therefore immune to vibration.
This ‚well-meant' measure is actually counterproductive as the 2.4
GHz receivers feature high performance ICs which have a certain
current consumption, thus resulting in intrinsic heat built-up. The
foam cladding about the receiver prevents the heat build-up from
dissipating from the receiver.
We recommend mounting 2.4 GHz receivers with double-sided adhe-
sive tape with a foam coare (or Velcro strip). If possible, not over
the entire area but on „feet" to enable air to circuilate around the
receiver. Installing receivers vertically will icrease the air circula-
tion.
The temperature range for remote control components is generally
between -15 °C and +55 °C. This is the typical range that is speci-
fied by manufacturers of electronic components. This temperature
range applies to virtually all electronic devices for everyday use.
For years now, this is also the temperature range (–15...+55 °C) that
has been specified for receivers and, of course, also for the new
generatiion of 2.4 GHz
FASST receivers. This temperature range is also stipulated for other
2.4 GHz systems as they use ICs based on WLAN technology
which are normally used „at home" and therefore have the same
specifications. The specified values are, of course, theoretical limits
and in practical applications receivers can easily cope with consi-
derably higher ambient temperatures (approx. 70-75 °C). Never-
