7.2 Binding
Before it can be used, the receiver must be linked to the trans-
mitter using the process known as “binding”.
! Note:
The signal output to the servo sockets is switched off during the
binding procedure. This means that the servos are “soft”, and do
not move, while the motor connected to a modern electronic
speed controller remains OFF due to the lack of a signal. Never-
theless, it is important to secure the model and keep well clear
of the power system.
The binding process is necessary in the following cases:
The first time the receiver is used ( 7.2.1).
After a receiver RESET ( 7.5).
If you change the “Fast response” setting at the transmitter.
Please read the appropriate section in the instructions
supplied with your transmitter or RF module.
If you change the setting at the transmitter which defines the
transmitted frequency range. For more information on this
matter, please refer to the operating instructions supplied
with your transmitter or RF module (“France mode”).
If the receiver is to be operated in conjunction with a different
M-LINK transmitter.
7.2.1 Sequence of the binding procedure
1. The first step is always to set the transmitter and receiver to
Binding mode:
a. Place the transmitter very close to the receiver aerial.
b. Switch the transmitter ON in binding mode.
! Note: please read the operating instructions supplied
with your M-LINK transmitter or RF module for details.
c. Switch the RX-5 slim M-LINK receiver ON in Binding
mode:
Locate the SET button on the top of the receiver and
hold it pressed in.
Switch the receiver ON, or connect the battery.
Now release the SET button (not before):
The binding procedure runs, the LED on the
receiver flashes at a high rate
(LED code 2 7.1).
2. Once the transmitter and receiver are bound, both units
switch automatically to standard transmit / receive mode:
The LED on the receiver flashes slowly
(LED code 3 7.1).
! Note: in most cases the binding process only takes a few
seconds.
7.2.2 Binding: locating and correcting faults
Fault:
During the binding process the receiver LED continues to flash
at a high rate after several seconds.
Cause:
No M-LINK signal of adequate strength detected.
Remedy:
Reduce the distance between your transmitter and the recei-
ver aerial.
Ensure that your transmitter is switched on in binding mode.
Repeat the binding procedure.
7.3 Switching the receiver ON and OFF in normal
mode
7.3.1 Sequence when switching ON and OFF
This is the procedure for switching the RC system ON:
1. Switch the transmitter ON.
2. Switch the receiver ON.
3. The receiver LED flashes slowly and evenly
(LED code 3
7.1
):
An M-LINK signal is being picked up:
the RC system is ready for use.
This is the procedure for switching the RC system OFF:
1. Switch the receiver OFF.
2. Only now switch the transmitter OFF.
7.3.2 Locating and correcting faults when switching ON:
The receiver LED lights up constantly when switched on (LED
code 1 7.1), but does not flash.
Cause:
No M-LINK signal detected.
Remedy:
Is the transmitter switched on?
Is the transmitter generating an M-LINK signal?
Are the transmitter and receiver bound to each other?
Have you carried out a receiver RESET ( 7.5, 7.2)?
Have you made changes to the “Fast response” /
“France mode” setting ( 7.2)?
Fault:
The receiver LED remains off when the unit is switched on
(LED Code 0 7.1).
Cause:
The operating voltage (battery voltage) is too low.
Remedy:
Charge the receiver battery or flight battery, or replace it with
a charged pack.
7.4 HOLD and FAIL-SAFE
If the receiver detects invalid data (interference), the last valid
data is sent to the servos in order to bridge the period of signal
loss (HOLD mode).
The effect of the FAIL-SAFE setting is that the servos run to a
previously selected setting if interference should occur, once the
HOLD period (0.75 seconds) has elapsed.
In its default state and after a RESET the FAIL-SAFE function is
switched OFF, and is only activated when you select the FAIL-
SAFE settings for the first time. FAIL-SAFE is set using the SET
button on the receiver.
!
Note:
if you are using a
COCKPIT SX, ROYALevo
/
pro
/ SX
or Profi TX transmitter, you can also set FAIL-SAFE directly from
the transmitter.
