    This manual describes the technical description of the unit, installation and operation. There are two hardware versions of Boxi device: Boxi and BoxiII. This manual is for Boxi II version only. Boxi II units are shipped from May 2021. General Description Boxi is an electrical actuator control box.

  • Page 9: Analog Input

    Boxi II – Manual 2.3 Analog Input Analog Input Analog input consist of two analog inputs and a reference voltage input/output. It is able to measure voltage from various sensors used for detecting trim and/or flap position. Boxi outputs a weak reference voltage to be used with simple resistor divider sensors (potentiometer).

    The switching is fast and at fixed frequency. With change of PWM duty cycle the soft start of motor is realized in Boxi II. On figure 1 the idea of soft start is presented. On keypress on Joyu the Trim output starts switching with cycle period.

Figure 3 illus- trates connection of standard devices to Boxi. Power Boxi shall be connected to the aircraft power supply. Because Boxi controls essential devices like PTT for the radio it should get a power supply as soon as the master switch of the aircraft is turned on.

    5A. Boxi must be connected to primary CAN bus in order to control any supported Kanardia device via Joyu (refer to Figure 3). Use standard RJ45 ethernet cable to connect it with other Kanardia devices.

    Boxi II – Manual 4.4 Trim 1 and Trim 2 4.3.2 Two Microphones When two microphones are connected to the radio, the radio must distinguish between microphone in use. Radio will open microphone for which the button is pressed and suppressed the other one. So, two switches are needed in Boxi, Ptt1 and Ptt2.

    Figure 8: Connection of external relay for driving high current motor. Position Input The Boxi II includes also two analog inputs for position sensors. Most of the position sensors are simply variable resistors - potentiometers, which work as a voltage divider. The voltage divider must be connected to a voltage source which we will refer to as a reference voltage.
