The Central Box 400 is a switchboard designed for the complete
management of servos in large to giant models with an emphasis
on safety. The Central Box 400 has a unique design that provides
overload protection at each servo output. An independent, very
powerful BEC (battery eliminator circuit) for each battery input
makes the Central Box an optimal solution to connect up to 24
servos. The Central Box 400 can manage the batteries and fully
supports the JETI EX telemetry system. Up to two receivers with
serial (PPM, EX Bus, UDI) output can be connected to the Central
Box 400. With a JETI DC/DS transmitter, the full potential of the
Central Box can be used, such as easy configuration of the Central
Box, EX telemetry, and very fast servo response.

2 Description
Central Box 400 has 24 outputs for servos with individual
overload protection. More over, outputs Y17-Y24 can be
configured as:
servo output
logical input
logical output
Control signals generated by the Central Box to servos are 5V. This
solution ensures reliable servo signal transfer for longer distances.
Ext1 - Ext4 ports can be configured for use as:
inputs for telemetry sensors
EX Bus expanders - used for connecting devices which support the
EX Bus protocol (the Central Box, a sensor,...)
Ext4 - slot is also used as an output to connect a JETIBOX to
configure the Central Box and for the firmware update connection
Rx1 - primary input for connecting receivers with serial output (EX,
PPM, UDI)
Rx2 - secondary (backup) input for connecting receivers with serial
output (EX bus, PPM, UDI)
Switch slot is reserved for connecting magnetic switch or RC Switch
BEC output serves as the output for stabilized voltage to power
supply other Central Boxes that can be power supplied from the
Central Box 400. The voltage at the output has the same level as the
voltage for supplying the servos. Voltage for the servo outputs is
adjustable from 5-8V with 0.1V steps.
For more safety, the Central Box 400 contains two BEC regulators
connected in parallel. Information about the correct power supply
and a faultless condition of the individual branches is indicated by
green LED and also by telemetry. It is not recommended to use the
BEC outputs for direct power supply of servos or receivers with
servos. These devices are not individually protected. If one element
of the branch supplied from the BEC output is overloaded, the

To avoid accidentally disconnecting or pulling the cable with the JR
or MPX connector out, e.g. due to vibrations, it is possible to install
safety mechanism for connectors on the Central Box. Safety
mechanism for connectors fixes not only connectors of servos,
receivers, and sensors, but also BEC outputs (MPX connectors), see
chapter Safety mechanisms of connectors

3 Connection
3.1 Power supply of Central Box 400
The Central Box 400 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.
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. The selection of battery to supply power is based on the
voltage set in individual BEC´s. During use, the power is actually
supplied from the battery whose BEC has higher voltage set. If the
voltage 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 safely 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 either the
BATT1 or BATT2 input.
