The Central Box is a switchboard designed for the complete
management of servos in a model with an emphasis on safety. The
Central Box 320 has a unique design that provides overload
protection at each servo output. The Central Box 310 offers
maximal unreduced power for each servo (servo outputs do not
have overload protection). The Central Box can manage up to two
batteries and fully supports the JETI EX telemetry system. Up to
three receivers with serial (PPM, EX Bus, S.BUS) output can be
connected to the Central Box 310 and 320. With JETI DC/DS
transmitter, the full potential of the Central Box can be used, such as
an easy way to configure the Central Box, EX telemetry, and very fast
servo response. Central Box 310 and 320 have a fully adjustable and
very powerful BEC for powering all connected servos.

(EX bus, PPM or S.BUS)
• SWITCH - input is reserved for connecting a magnetic switch or RC
switch (optional accessories).
• BATT1 and BATT2 – MPX connectors for connecting to power the
servos and receivers connected to the Central Box.

2.3 Magnetic switch
The magnetic switch is used to turn the CB 310/320 ON or OFF . The
magnetic switch is connected to Central Box 310/320 by the
interconnection cable from normal Master port on the magnetic
switch to a slot labeled "SWITCH" on the Central Box 310/320. 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).
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

3.1 Power supply of Central Box 310/320
The Central Box 310/320 can only be powered from batteries
connected to BATT1 or BATT2. When selecting the power supply it
is necessary to follow the power requirements and the number of
the servos you use. Batteries for power supply must be sufficiently
large to prevent a decrease of the output voltage for servos when
loaded (voltage depression) and to allow the overload protection
function properly (Central Box 320).
Together, both power supply methods must be able to supply a 20A
continuous and 120A peak current. To take full advantage of
internal BEC we recommend to power the Central Box from three
Lixx cells.
The power batteries are connected to the Central Box using MPX
connectors. The Central Box allows up to two batteries to be
connected. If the voltage of the batteries is the same, the power can
be used from both batteries at the same time. This rule applies to
the standard power supply. This means that the power battery
voltage should be greater than the required BEC voltage setting.
When the voltage of the batteries is different, the power is not
shared and each pack is isolated from the other. This allows you to

reasons, always switch the system off via magnetic switch before
disconnecting the power batteries.
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.
3 Connection
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.
