WIRING CONNECTION INTO THE FRONT:

- Optical sensors are used for detection the selector plate and the sector gear
- Tactile trigger switch makes short click for great hair trigger mod.
- Unique real feel trigger system (RFTS) simulates trigger feeling like in the real gun. It adds secondary resistance with release after the fire. Feeling is comparable to shooting with real caliber 22lr in AR15

MAIN FUNCTIONS:
- Adds new shooting modes independent for every position on the fire selector (SAFE - SEMI - AUTO)
- Three adjustable bursts (range 2 - 20 shots)
- It preserves empty magazine detection like the original gun
- Rate of fire can be reduce to 40%. It add breaks between shots to reduce RoF. It gives fast trigger response even with very low rate of fire, just like in a real gun
- Adjustable strength active braking (can be disabled)
- Pre-cocking function for instant shot on SEMI fire
- Delay between shots adds time in which isn't possible to shoot, it simulates the delay from gun reload or recoil (range 0,1 - 4,0 seconds)
- Electronic fuse set sensitivity for high current detection to avoid any damage if something goes wrong
- Low battery indication for 2S - 4S li-pol and 3S - 4S li-fe
- Virtual magazine simulates low capacity magazines, it will force the gun to stop shooting when it reach 0. There can be set warning after shot before empty magazine and how it will be reloaded
- On the board are input and output ports for controlling external devices or Leviathan
- Statistics screen shows shooting output with cycle timing, motor current consumption, rate of fire and temperatures. It allows you to do fine-tune gearbox upgrade
- Application shows actual battery voltage value. Color lines indicates battery charge status where green is OK, orange will warn after each shot and red will not allow to shoot
- User can save multiple settings under profiles
- Update function fixes bugs and adds new features to the device
- There are three shot counters. Total count every shot during the device lifetime. User counter can be reset by user anytime. Power-up counter is reset by battery connection
- Error log shows errors made during the device life also can be erased by user
- For better security wireless connection can be disable by the selector switch (can be deactivated)
- Leviathan monitors current, voltage and temperature to avoid any damage when something go wrong.
- Motor vibrates and beeps as a feedback for user
- Programmed settings are saved in the Leviathan memory immediately after their change, so you can immediately test it and settings aren't lost when is battery disconnected or lost connection with smartphone
- New functions are for free for every user via online update function

FIRE MODES:
Independent for every position on the fire selector (SAFE - SEMI - AUTO)
- SAFE: no responding on the trigger pull.
- Semi: it fires single shot per trigger pull.
- Semi/BurstX: short trigger pull fires single shot, long trigger pull fires burst.
- Binary trigger: it fires single shot when trigger is pulled and another single shot when is released.
- BurstX: gun shoot burst per trigger pull.
- BurstX+BurstY: short trigger press fires burstX, long trigger press makes burstX+burstY fire.
- BurstX/Full: short trigger press fires burstX, long trigger press makes auto fire.
- Full: gun makes auto fire until releasing trigger.
- Virtual reload: pull trigger to reload virtual magazine

EXTERNAL INPUT:
Works with Input connector

- OFF: Every signal to Input terminal is ignored.
- External trigger: gun trigger is disabled and replaced by micro switch connected to Input (SIG and GND)
- Burst-3 trigger: micro switch connected to Input (SIG and GND) make 3 burst fire when it is pressed. Gun trigger is still functional.
- AUG trigger: selector plate detection is disabled. Gun trigger is set to selector on semi. Micro switch connected to Input (SIG, GND) is set to selector on auto.
- Empty mag (NO): Micro switch activates empty magazine detection, when is connected SIG with GND.
- Empty mag (NC): Micro switch activates empty magazine detection, when is disconnected SIG with GND.
- Virtual reload: Micro switch activates virtual magazine reload, when is connected SIG with GND.

EXTERNAL OUTPUT:
Works with Output terminal:

- OFF: output terminal works only if the Input terminal activates it.
- Motor: output terminal is ON with gun motor + with IN activation.
- Motor + Xs: output terminal is ON with gun motor with time delay after gun motor is deactivated + with IN activation.
- Always on: the output terminal is constantly activated.

 TECHNICAL SPECIFICATIONS:
- Easy installation inside the gearbox version 2, compatible with Tokyo Marui standard
- You don‘t have to modify the gearbox V2 from the Krytac company. Simply cut the Leviathan bottom board
- It uses optical sensor actuated by sector gear cam for perfect semi and burst fire timing
- For fire selector position is used optical sensor too - it works with sticker provided with Leviathan
      
- Tactile trigger switch makes short click for great hair trigger mod.
- Unique real feel trigger system (RFTS) simulates trigger feeling like in the real gun. It adds secondary resistance with release after the fire. Feeling is comparable to shooting with real caliber 22lr in AR15
- Thanks to advanced electronics, Leviathan - V2 optical can be used with any common gearbox upgrade and gun rate of fire
- Completely made wiring allows the fastest and the easiest installation into the gun, it is long enough for all kind of weapons with battery placed in the stock. No soldering is needed
- The wire length between the gearbox and the battery connector is 270mm
- There are high quality power wires 1,5 qmm (AWG16) with thin and hard teflon insulation (PTFE) and signal blue wire 0.34 qmm (AWG22) with teflon insulation too
- Power wires outer diameter is only 2,10 mm and blue wire 1,30 mm
- Board covered by conformal coating, it protect Leviathan against damage from water
- On the board is input port for controlling output port, 3rd burst, external trigger, magazine reload, etc. and output port for the hop-up chamber BBs illumination, powering electric magazine, flashlight, laser, etc.
   
- For right pre-cocking function is necessary to have in the gearbox functional antireverse latch. WARNING: it increases wear and tear on the gearbox.
- Specified for common batteries up to 17V (Ni-xx 8.4 - 12V, lipol 7.4 - 14.8V)
- Device increases gun rate of fire and battery holds longer, than with basic wiring
- With active braking ON piston isn't partially stretched, spring is fully released, parts in mechabox aren't under strain and nozzle locks hop-up chamber in greater part (depends on ROF)
- In weapons with very high rate of fire (ROF) active brake solves multiple shots in semi mode
- The braking effect is the most powerful with high torque motor. Note: Lower braking intensity spares the motor coils.
- Remove from the gearbox: cut off lever, trigger, trigger contacts and trigger block, you will not need them with the Leviathan - V2 optical

USE WITH BRUSHLESS MOTOR:
- Leviathan can be used with brushless motor (Warhead, Option No. 1, etc.)
- Activate function "Brushless motor" in the Leviathan app and use all available options without any worries.

PACKING:
- Leviathan - V2 optical drop-in electronic module with wiring to front, T-plug connector and faston connectors to the motor
- CNC trigger with zero path adjustment screw (different variants)
- Screw for securing device in the gearbox
- 2pcs wires holders
- 3x Leviathan sticker
- Dogtag keychan
- Foams to keep device in place

SAFETY WARNING:
- Installation of this device into the gearbox requires advanced technician skills!
- Please read these informations before installing your device to prevent any damage.
- Short circuit or incorrectly connected battery will cause immediate damage to the device which is not covered by the warranty. It can lead to fire or even battery explosion.
- Disconnect battery, when you aren't using the gun! Otherwise you will fully discharge the battery. Because the device drains small amount of current from the bettery all the time.
- Do not connect battery when gun pointing towards you, another person or an animal.
- Do not modify, repair and put into any kind of liquids or thermal shock the Leviathan - V2 optical.
