      warning sound.
    • Block-up protection. When gearbox Block-up occurs, the system stops
      working and emits an elongated ‘1~’ beep. Please check the gearbox
      immediately by power off.
    • Auto-loading function is designed for gel ball blaster magazines with
      motor inside, when changing the magazine, the magazine motor will
      run automatically for a period of time, and the length of time can be
      programmed by 9th option.
    • This module is able to increase rate of fire, the stability of single-shot
      and make batteries have higher durability.
    • The energy that support the active brake function comes from the
      inertia of motor, stop the piston without delay. The effect of active
      brake is significant on high torque motor
    • The active function prevents the over-spin of gears, this solve the
      issue that the single shot becomes multiple shot under high voltage. Meanwhile, the spring is fully released in semi-auto mode and parts in
      gearbox are not under strain, increase the life cycle of gearbox and
      parts.
    • The system includes multiple shooting mode, these modes can be
      selected by fire select switch
    • The default position of the piston is adjustable in semi-auto mode. Pre-cocking function can be implementing, zero trigger delay
    • Adjustable rate of fire, the gap between two single shots can be
      programmable, to achieve adjustable rate of fire
    • When the DTU is overheated, after the trigger is pulled, the motor will
      give a beep prompt until it is automatically restarted after cooling.

    Modes:

    • SAFE:This mode is completely the same as original safe mode. The trigger
      can be pull but nothing happens. This mode can be programmed to semi-auto, double stroke single shot, 3-round burst to 6-round burst,
      the default mode is safe mode
    • SEMI: This mode can be programmed to semi-auto, double stroke single shot, 3-round burst to 6-round burst, the default mode is semi auto
    • AUTO: This mode can be programmed to full-auto, 3-round burst, 6-round
      burst and 9-round burst, the default mode is Full-auto

    Sensors:

    • Receiving sensors: 5 trigger receiving sensors, 1 gear receiving sensor, 1
      semi-auto sensor and 1 full-auto sensor.
    • Transmitting sensors: 1 trigger transmitting sensor, 1 gear transmitting
      sensor and 1 selector transmitting sensor.

    How does it works: The transmitting sensors emit light of a specific frequency, and the receiving sensors change the output signal when it receives it. The
    DTU reacts according to the signal of the receiving sensors. Sunlight and
    some lights contain light of that specific frequency, be careful to avoid
    interference and keep the sensors clean.

    • Gear sensors: When installed correctly, the gear transmitting sensor and
      the gear receiving sensor are located on both sides of the sector gear. When
      the sector gear rotates to a specific position, the gear receiving sensor will be
      blocked, so that the gear receiving sensor can not receive the signal from the gear transmitting sensor. The DTU detects the angle of the sector gear
      according to the output signal of the gear receiving sensor.
    • Trigger sensor: When installed correctly, the trigger transmitting sensor
      and the trigger receiving sensors are located on both sides of the trigger. When
      the trigger is fully released, the trigger receiving sensors will be blocked, so
      that the trigger receiving sensors can not receive the optical signal from the
      trigger transmitting sensor. When the trigger is pressed, the trigger will no
      longer block the trigger receiving sensors, and the trigger receiving sensors
      can normally receive the signal from the trigger transmitting sensor. The DTU
      detects the angle of the trigger according to the output signal of the trigger
      receiving sensors.
    • Selector sensors: Selector sensors need white sticker on selector plate to
      work correctly, When installed correctly, the optical signal emitted by the
      selector transmitting sensor is reflected by the white sticker and received by
      the semi-auto and full auto sensors. The distance between the white sticker
      surface and the sensors cannot be greater than 2mm and less than 0.5mm

    1. When the selector plate in the SAFE position, the white sticker reflect
      nothing, the semi-auto sensor and full-auto sensor can not receive the
      optical signal.
    2. When the selector plate in the SEMI-AUTO position, the optical signal from
      the transmitting sensor is reflected by the white sticker and received by the
      semi-auto sensor, but the full-auto sensor can not receive the optical
      signal
    3. When the selector plate in the FULL-AUTO position, the optical signal fromthe transmitting sensor is reflected by the white sticker and received by
      both the semi-auto sensor and the full-auto sensor.The DTU detects the position
      of the selector according to the output signal of the semi-auto and full-auto sensors.

    Requirements:

    • High-power soldering iron (higher than 50W) is recommended, solder the
      clop with 0.5sqm soldering wire and soldering rosin. Please ask
      professional for help if you do not know to solder.
    • Please use Spring smaller than M150.
    • Use high torque motor(no load current less than 3A) can stop the motor
      faster and prevent DTU from overheating.
    • In standby state, the current of the system is smaller than 0.05A. Please
      disconnect the battery if it is not used for a long time.

    APP for Android:

    Download and install the. APK file from the website: http://github.com/t238. After installation, enter the settings -> APP&notification, find the “T238DTU”, go to APP permissions -> location permission, and select “Allow all the time”. This will allow the smart phone APP to fine the Bluetooth devices.

    Bluetooth:
    Bluetooth programming function will be turned off in 30 seconds after power on. Connecting DTU with smart phone needs to be completed within 30 seconds
    after power on, otherwise, the DTU needs to be powered off and powered on
    again. Open the app, click “Search” button to find the Bluetooth device “T238DTU” and connect it.

    Trigger calibration:
    There are five trigger sensors, which are convenient to adapt to different
    trigger rotation angles. When using DTU for the first time, trigger calibration is
    required. The specific operation is as follows: install the gearbox, grip and
    motor, connect the battery, when the prompt tone “1~2~3~3~2~1~” is heard, hold the trigger, and then release it. After repeating three times, the prompt
    tone “1~2~3~” will be heard, indicating that the DTU has been calibrated. The
    trigger rotation angle of different gearboxes is different, so it needs to be
    recalibrated when replacing gearbox or trigger. To recalibrate the trigger, connect the app and restore the DTU to the factory settings. Restore factory
    settings is in the “Module parameter set”.
    Sensors monitor:
    Open the app, click “Search” button to find the Bluetooth device “T238DTU” and connect it.

    Go to “DTU Sensors Monitor”, and enable the “Enable monitoring” checkbox, move the trigger, selector plate and the sector gear to see if the corresponding
    checkbox changes. If no, means that the corresponding position sensor is
    faulty or the installation is faulty, and the corresponding sensor cannot be
    triggered. It is suggested to open the gearbox for investigation.
