2.3 Magnetic switch ( Central Box 200 only)
The magnetic switch is used to turn the Central Box 200 on or off
and is connected to a separate slot labeled “Switch”. To turn on the
Central Box using the magnetic switch it is necessary to hold the
supplied magnet carrier (key) to the target so that the carrier (key)
and the target on the magnetic switch are properly oriented
(align the dots).
Fig. 3: Description of magnetic switch and the key
Green LED
- flashing LED signals proper detection of the magnet key
- steady LED signals “On” state
When the magnet key is held to the target in the proper orientation,
the green LED glow steadily after 1 second indicating that the
electronic switch is turned on.
Switching off is done in a similar manner, when the magnet key is
held to the target in the proper orientation, after 1 second, the
green LED goes off and the system switches off.
If the switch is not plugged in the Central Box, the Central Box is
switched on.
The system remembers whether it has been switched on or off. If
the system is switched “on” via the magnetic switch and then the
power supply is disconnected, when the batteries are re-connected
to the system automatically returns to the “on” state. For safety
reasons, always switch the system off via magnetic switch before
disconnecting the power batteries.

EN
When turning on, connect the batteries first and then turn the
system on via magnetic switch. Keep the same rule when switching
off. First switch the system off via magnetic switch and then
disconnect the batteries.
The Central Box is connected to the power supply, receiver, servos,
controller/controllers and eventually sensors. Please follow the
subsequent general guidelines about proper connection of the
Central Box and these other components.
3.1 Power Supply
The Central Box can be powered from batteries which are directly
connected, from voltage regulators connected to batteries or via
BEC. When selecting power sources for the Central Box, be sure to
follow the minimum power requirements. Together, both power
supplies methods must be able to supply a 15A continuous and
90A peak current. If the power source is not strong enough, the
overload protection feature of the Central Box may not function
correctly.
The power batteries are connected to the Central Box using MPX
connectors. The Central Box allows up to two batteries to be
connected. During use, the power is actually supplied from the
battery with the higher voltage. If the voltage is the same, the
power can be used from both batteries at the same time. When the
voltage of the batteries is different, the power is not shared and
each pack is isolated from each other. This allows you to use
batteries of different capacity, number of cells, and chemistry type.
If the power for the Central Box is provided only from one battery, it
can be connected via BATT1 or BATT2 input.

Central Box does not contain circuitry to stabilize or regulate
voltage to the servos.
The level of the input voltage is equal to the level of (output) supply
voltage level to the servos. Be sure to match the proper type of servos
with your selected power supply. Eg. when using 2 Li-xx cells without a
regulator, it is necessary to use servos labeled “High Voltage”.

3.3 Connecting Central Box – PPM variant
The receivers can be connected to the Central Box using the Rx1
and Rx2 inputs.
The Ext1 port is for output of telemetry data from the Central Box in
the form of EX telemetry. To use the Central Box telemetry and other
sensors connected to it, use a Duplex EX receiver. Simply connect
the Central Box output labeled Ext1 with the Duplex EX receiver
input labeled Ext.
Channels 14 and 15 can be configured as servo outputs, or as
inputs for telemetry sensors .( Central Box 200 only)
Configuring the Central Box is in this way done by using a JETIBOX;
either directly connected to the Central Box, or wirelessly using a
JETI transmitter.
Caution: It is not recommended:
- to connect more Central Box outputs to one servo
- to use a Y cable (connecting two servos to one
output)

3.4 Connecting Central Box – EX Bus variant
Receivers can be connected to the Central Box using the Rx1 and
Rx2 inputs.
Ext1 is an input for telemetry sensor. Telemetry is transmitted to the
receivers via EX Bus.
Channels 14 and 15 can be configured as servo outputs or as
inputs for connecting telemetry sensors ( Central Box 200 only).
Configuring the Central Box is in this case done directly in the
transmitter via EX Bus.
When operating the Central Box with DC/DS transmitter, it is
recommended to use two receivers communicating with the
transmitter in the wireless mode "Double path".

you can also select how the Central Box responds at the signal loss
for each of the individual outputs (OUT off, hold, fail safe).
• Signal Fault Delay – the length of time from when the Central
Box detects a signal loss to when the programmed Fail Safe output
is performed. During this time the last servo input is held. After the
selected time has elapsed, the Central Box outputs behave
according to setting for each specific output.
• Output Period – setting for the period of the output signals
(default Auto-synchronous mode with the transmitter ). This
parameter significantly affects the behavior of the servos. For
analog servos the reaction (response) accelerates and the power
