Features Everything you need out-of-the-box Quantum Trigger included in the kit No need to use USB-Link for installation and configuration New noise-resistant trigger detection algorithm Hair-trigger out-of-the box. Even 60 trigger sensitivities for the 1st mm (0.04 in) of movement Additional protection against interferences thanks to multi-layer PCB with EMC shield Automatic Pre-Cocking: LOW / MID / HIGH Trigger sensitivity adjustment without any limitation, Improved cycle detection Active brake adjustment: Adaptive / 100% / 60% / Brushless motor / OFF New selector mode: SAFE - SEMI - BINARY instead of SAFE - BINARY - AUTO GCS App allows for making firmware updates via the internet, which enables quick applying of improvements ASTER SX for V2 gearboxes the natural successor of ASTER SE merges years of experience with cutting edge tech. ASTER SX is fully compatible with popular brushless motors even with batteries up to 11.1 V. The unit heats up less even while accommodating higher loads. ASTER can operate with stronger springs and more demanding configurations. ASTER SX comes with a free Quantum Trigger, so you can easily set sensitivity from ludicrous touch through hair to full movement. Improved programming via trigger gives you settings such as automatic Pre-Cocking, trigger sensitivity adjustment, Active Brake settings with top-class adaptive mode. Calibration available just via trigger and selector movement. ASTER V2 SX turns your AEG into future-proof advanced training equipment. All this, along with a thicker and sturdier PCB 1 mm in thickness makes ASTER V2 SX one of the most durable ETUs on the market.What distinguishes ASTER V2 SX from the competition?ASTER is future-proof, thanks to compatibility with USB-Link and Blu-Link. You can update your firmware and get new options, connect additional accessories, check telemetry.What is an ETU? It is an Electronic Trigger Unit replacing trigger contacts and the cut-off lever, which takes control of your AEG. ASTER gives you great flexibility and is future-proof. Today you can program the most important functions with the trigger, and tomorrow you can borrow a USB-Link or Blu-Link from a friend to configure advanced functions, perform a firmware update, run diagnostics or use the GCS app on a smartwatch Hair-trigger up to 60 sensitivity in the first millimeter of trigger movement Top-notch automatic pre-cocking Foregoing reverse polarity protection in exchange for unparalleled performance You can update its firmware via the Internet ASTER is a part of the GATE Ecosystem Lowest in the market current consumption. Deep sleep mode with only 0.29 mA current consumption prevents battery discharge Built-in voltage boost converter allows for trouble-free operation with weaker batteries and increases the switching efficiency 3.75 V ready it operates at very low voltage (even 1.2 V during the shot), which is important in high-tuned AEGs, where the voltage under load drops significantly Sensor that supports Infinite Torque-up, DSG, SSG, 19-tooth and standard gears The possibility of using a mechanical trigger lock Compatibility with brushless motors Why ASTER's programming via trigger is user-friendly? You do not need to rush You can navigate the menu very quickly and efficiently or slowly and calmly The colors of the led lights are only a help you can rely on the vibration of the motor In case of any problems, you can use the very popular USB-Link or Blu-Link and use the GCS App What is the self-learning automatic pre-cocking? Thanks to Pre-cocking, you gain trigger reaction similar to real life It will automatically set piston position It is easy-to-use, just set one of the 3 modes: LOW, MID or HIGH It automatically adapts to the battery voltage and rate of fire Connect your ASTER V2 SX with the GCS App and get total control of your AEGYou choose how to configure ASTER V2 SX simply via trigger or through USB-Link / Blu-Link and our advanced GCS App. You can ask your technician to update ASTER V2 SX firmware using Blu-Link or USB-Link, carry out diagnostics or change settings in a very convenient way. You can also get your own Blu-Link and use the Smartwatch app, giving you real-time data to reinforce your tactical decisions.Control your airsoft replica from your iOS, Android, macOS or Windows device using an additional dongle USB-Link or BluLinkSet trigger sensitivity exactly as you like and adjust other ASTER V2 SX settings in a simple wayUse automatic Pre-Cocking to gain a trigger reaction just like in a real replica How to update firmware: Plug Aster battery connector into USB-link or Blu-Link and connect it to a Cell phone or PC with the GCS app installed Go to Status panel and select the most current firmware version If not already installed, click "update". this process should take ~2 min to install. all of your previous settings will be saved
