Receiver▋Connections
Receiver Connections to the servos and the
power supply
JR labels the channels on the receiver with
names rather than numbers. From this point
onward in the manual, the receiver channels
will be described using their names.
Since the receiver is susceptible to
vibration, shock, and water, anti-vibration
and waterproofing measures should be
implemented.
If the connectors become detached while
flying, there will be a risk of uncontrolled
operation. Please securely insert all of the
connectors as far as they will go.
In the situation where relay connectors
(ex tension leads) a re used dur ing
installation rubber sponge should be
wrapped round the connectors to fix them.
Be absolutely sure not to leave the
connectors hanging unsupported.
XBus
The all new XBus system uses JR's own
serial bus data instead of PWM (Pulse
Wide Modulation) to communicate with
XBus products such as servos.
Control signals are sent in a serial
manner to all channels, with individual
servos recognizing their own data from
receiver.
Non XBus servos can still be used in
conjunction with a channel decoder (e.g.
XB1-CPR), or plugged directly into the
receiver (avoiding the XBus port).
Never plug any non XBus device into the
XBus system as a failure is sure to occur.
On large models, our optional XBus
power hub allows servos to receive a separate power supply.
Our new XBus receiver is also able to be plugged directly into compatible helicopter FBL units, allowing a
single connection between the receiver and FBL unit.

Due to the 2.4GHz band which has a strong directionality in
its radio waves, the receiving sensitivity will greatly differ
depending on the direction against the antenna. Since the
antenna receives radio waves from the sides rather than
from the tip, please take adequate care of the antenna
direction when installing the antenna in the model.
The built-in antenna of the remote antenna is
installed on the surface of the circuit board.
Care will be required in the situation where the
built-in antenna has been installed beside a
shielding material, since the receiving
sensitivity will be considerably degraded.
* The remote antenna receives the data and also
feeds back to the transmitter.
The antenna part should be installed
in a perfectly straight condition.
Coaxial part of the antenna can
be bent however, do not bend it
in a right angle. This will damage
the internal antenna wires.
If each antenna is installed in parallel, the receiving
efficiency will be reduced.
