Channel Assignment, Input Side; Failsafe And Hold Function - PowerBox Systems Royal SRS Instruction Manual

- Now set the appropriate end-point using button I or II before concluding the procedure with the
SET button.
- Move the transmitter switch to the "retracted" position, then press the SET button again.
- Now set the corresponding end-point with button I or II, and conclude the procedure by pressing
the SET button.
- Both landing flaps will now move synchronously.

5. CHANNEL ASSIGNMENT, INPUT SIDE

Modern SRS bus technology makes it possible to assign any channel to any function without res-
triction. The Input Mapping function is only required if you wish to set up the iGyro or door sequen-
cer manually, i.e. without recourse to the Setup Assistants. This function is required for models
fitted with canard surfaces or a thrust vector control system, so that you can adjust gyro gain for
the canards or thrust vector system separately from the main control functions.
The INPUT MAPPING menu point can be used to assign a channel to the following functions:
2 x Gyro aileron
2 x Gyro elevator
2 x Gyro rudder
6 x Gain Normal mode
6 x Gain Heading mode
1 x Gyro flight mode
1 x Door sequencer switch
To assign a channel, use the SET button to select the appropriate function, then move the transmit-
ter stick, rotary knob or switch which is to be assigned. Obviously the transmitter control concerned
must already be assigned to a channel at the transmitter.
Note: if more than one channel is assigned to one transmitter control at the transmitter (e.g.
channels 2 and 6 for ailerons), move the transmitter control repeatedly away from the centre
and back to centre again until the desired channel is selected. Alternatively you can use but-
tons I and II to assign the channel.

6. FAILSAFE AND HOLD FUNCTION

The integral Fail-Safe and Hold function makes it possible to program fail-safe or hold mode in the
Royal SRS without recourse to the transmitter or receiver. Each output can be set up individually.
Example: it would be possible to assign fail-safe to throttle if complete signal loss occurs, while all
other outputs maintain the last known valid position.
It is important to be aware of this point: if you program fail-safe on one output, all other outputs
which have the same input channel will also be set to fail-safe. This avoids mechanical problems if
one control surface is operated by multiple servos,
because these are assigned to the same input.
The example shown below shows: output K and out-
put L are linked to Gyro Elevator A. Output K is set to
fail-safe, output L is therefore also programmed to
fail-safe automatically.
