The Central Box is a switchboard designed for the complete
management of servos in a model with an emphasis on safety. The
Central Box has a unique design that provides overload protection
at each servo output. The Central Box can manage two batteries
and fully supports the JETI EX telemetry system. Up to two receivers
with serial (PPM, EX Bus) output can be connected to the Central
Box. 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.

2 Description
2.1 Central Box 200
Central Box 200 has 15 outputs for servos with overload
protection.
Channels 14 and 15 are configurable as:
• servo output
• an input for telemetry sensor
Ext1 port can be configured for use as:
• an output to connect a JETIBOX or Duplex EX receiver to
either configure the Central Box or for the output of
telemetry data
• an input for telemetry sensors
3 EN
EN
The Ext1 slot is also used for the firmware update connection (using
the USBa).
Rx1 - primary input for connecting receivers with serial output (EX
bus or PPM)
Rx2 - secondary (backup) input for connecting receivers with serial
output (EX bus or PPM)
Switch input is reserved for connecting a magnetic switch or RC
switch (optional accessories).
BATT1 and BATT2 – MPX connectors for connecting batteries or a
BEC, etc., to power the servos and receivers connected to the
Central Box.

2.2 Central Box 100
The Central Box 100 has 8 servo outputs with overload
protection, labeled 1 through 8.
OUT/IN – universal input/output for switching additional
functions or for supervising the operational status
Ext1 – this port can be configured for use as:
• an output to connect a JETIBOX or Duplex EX receiver to
either configure the Central Box or for the output of
telemetry data
• an input for telemetry sensors
The Ext1 slot is also used for the firmware update connection
(using the USBa).

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.

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”.

3.2 Overload protection of servos
The Central Box has an overload protection circuit on every servo
output. In case of an overload, the affected servo output is
disconnected from the power supply while the remaining servo
outputs are still powered.
