Page 2: Introduction
ENGLISH 1 Introduction 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. -
Page 3: Attributes
Possibility to connect up to 2 receivers with serial interface (PPM, EX Bus) • Built-in Expander function for up to 3 sensors • Input for magnetic switch or RC switch (Central Box 200 only) • MPX battery input connector(s): 1x Central Box 100, 2x Central Box 200 •... - Page 4 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).

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... -
Page 7: Connection
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. - Page 8 RC Switch Magnetic Switch Rsat2 (Rx2) Rsat2 (Rx1) Input Voltage input voltage 4-14V Fig. 4: Example of the Central Box 200 powered for use with standard servos (voltage range up to 6V) Input Voltage 6V Rsat2 (Rx1) input BATT voltage 4-14V...

Page 14: Configuration Via Jetibox
4 Configuration via JETIBOX The JETIBOX terminal can be used for parameter setting and retrieving data. After connecting to the Central Box (output Ext1), a startup screen appears that contains identification of the device in the first line of the JETIBOX display. The second line contains the data showing the consumed capacity of batteries 1 and 2. -

Page 20: Configuration Via The Dc/Ds Transmitter
Configuration via the DC/DS transmitter The Central Box can be configured by a DC/DS transmitter via the Device Explorer menu. It is necessary to follow these rules for configuring the Central Box via transmitter: - Receiver firmware version Duplex 3.12 and newer (with setting Output mode->EX Bus) - The receiver must be connected to the Central Box via EX bus - Transmitter firmware version 2.02 and newer + the device... -
Page 21: General Settings
5.1 General Settings • 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 consumption is higher when the values for the output period are lower. -
Page 22: Fail-Safe
5.2 Fail-Safe • Fail Safe – switches on/off the Fail Safe function. If the Fail Safe function is deactivated, there is no signal generated in any Central Box outputs at the signal loss. If you activate the Fail Safe function, you can also select how the Central Box responds at signal loss for each of the individual outputs (OUT off, hold fail safe).. -
Page 23: Servo Output Mapping
5.3 Servo Output Mapping • Servo No. – assigning outputs of the transmitter to the Central Box outputs (Output pin). • Group – assigns specific output to the group of output impulses that will be generated from the receiver in the same time Fig. -
Page 24: Telemetry Min/Max
5.5 Telemetry Min/Max • Clear Min/Max switch – here you can assign a control (switch, stick or knob) on the DC/DS transmitter which clears the recorded battery capacity and minimum/maximum values in the Central Box. • Clear Now – allows you to immediately clear the recorded battery capacity and minimum/maximum values in the Central Box. -
