3.4 Binding a receiver
Select the
Receiver button
from the Main menu. As you will
now see, up to four receivers can be bound to the
CORE
simultaneously.
It is even possible to use different types of receiver; for exam-
ple, one
PBR-9D
and one
PBR-5S
can be bound. All four
receivers are of “equal value”, i.e. there is no Master / Slave
assignment, and no restrictions in terms of telemetry. Teleme-
try sensors can be connected to all four receivers, all of which
send data to the
CORE
on an equal footing.
The receivers are identified by the four capital letters A to D. The same letters appear in the telemetry data sent from the receivers,
helping to differentiate between them.
3.4.1. Binding
There are two methods of binding receivers:
• Option 1
Connect a power supply to the receiver, and it will respond by flashing green at high frequency for ten seconds. Press the
Bind
button
on your
CORE
transmitter, and the receiver now binds to it; the LED lights a continuous green.
If you do not press the Bind button within the ten-second period, the LED switches to flashing slowly red – at this point the
receiver can no longer be bound to the transmitter. You can only re-start the process if you first disconnect the power supply.
• Option 2
Press the
Bind
button
on your
CORE
, then connect the receiver to a power supply. The LED switches to continuous green
once the receiver is bound.
Technical information: during the binding procedure the PowerBox CORE generates a random sequence from a total of more
than 32 million numbers; this is then used as the basis for calculating the hopping sequence and encoding the signals. The
likelihood that two identical codes could be generated is therefore very close to zero.
NOTE
3.4.2. Remove
The Remove button has an important function: if you wish to uninstall a receiver from a model, it is essential to remove that recei-
ver from the model memory beforehand using this button. If you simply uninstall the receiver without first removing it at the trans-
mitter, then the other bound receivers will not work when you next switch the system on. This is an important safety feature, as it
ensures that all the bound receivers are working when you switch the system on, i.e. before you take off!
3.4.3. Range check
The Range check function reduces the transmitter’s output power, thereby simulating a large distance between transmitter and
model. This enables you to determine any possible weaknesses in reception in the receivers. In range check mode all the con-
trols should work perfectly at a range of at least 50 m. During the Range Test you can see the values for Link Quality (LQI). This
enables you not only to see whether the radio link is working, but also the quality of the link. This can be helpful in determining the
optimum aerial positions in the model before you fly it.
