  • 01. Introduction

    Onboard HDMI and SMA ports combined with advanced I/O design and larger camera cage make Gremsy S1 a good alternative to Gremsy T1 for quickly and easily set up with various platforms.

    It provides high precision pointing accuracies in a small, lightweight body specially designed for industrial applications.

  • 02. Features
    HDMI Support
    Having HDMI port on the gimbal allows camera setup more convenient and clean.
     
     
    SMA SUPPORT
    Having SMA port on the gimbal allows GPS antenna of some special cameras (Dual Pro R, for example) could be connected easily without having the antenna cable get twisted during gimbal operation.
     
     
    SINGLE ARM DESIGN
    Having single arm design enables lightweight but still maintain rigidity and allow camera set up easier.
     
     
    YOUR DEVICE HUB
    Having more I/O ports to interface with external devices and third party products.
     
     
    Heated & Temperature Controlled IMU
    Heated and temperature controlled IMU sensor with advanced 6-point calibration allows reliable performance even in extreme weather. Temperature is maintained within 0.2 degrees Celsius accuracy.
     
     
    High Performance Gimbal Controller
    gMotion Controller, designed and made by Gremsy based on a 32 bit high performance ARM microprocessor providing fast response and accurate calculation. Sensor data and motors correction are updated as fast as 2000 times per second to enable incredibly smooth footage.
     
     
    CLEAN DESIGN - INTERNAL WIRING
    No exterior wires, more solid. This clean design helps the S1 overcome wind resistance with ease to bring out the best video quality while staying agile.
     
     
    COMPACT & ULTRA LIGHTWEIGHT
    Small in hand, powerful in the sky. The slimmed down S1 is small enough to fit into your backpack and take anywhere, yet strong enough to handle up to 1.5 lbs payload.

    Gimbal Mounting

    There are two ways to mount the gimbal:

    Using 4x M3 to mount the top part (4 threads are arranged 32mmx32mm in squared pattern) onto the frame or damping isolator.

     
     

    Using 4x M3 to mount the top part (4 threads are arranged 51mmx51mm in squared pattern) onto the frame or damping isolator.

     
     
     
  • 09. Powering Up The Gremsy S1

    After connecting to the power supply, the gimbal will perform series of alignments, self tests, which last about 5 seconds and will determine the status of the gimbal, indicated by the Status LED color. During this time, don’t touch the gimbal or camera.

    Always start the gimbal with a balanced camera set up otherwise after initialization the controller will return an error followed by a red color indicator.

     
    Step 1

    Make sure the gimbal is mounted to the drone and its power port is already connected to the power supply correctly.

     
    Step 2
    Wait about 5 seconds, do not touch the gimbal or camera. The gimbal will perform series of rotations and self tests.
     
    Step 3
    If the status LED is blinking green, the gimbal is ready for use. By default, the gimbal is in Follow mode if the motors are turned ON by the Function Button.
     
    If the status LED is solid red, something is wrong with the gimbal and motors can not start. Connect to the software/apps to check details of the error message.
     
    Read “LED STATUS INDICATOR” in next section for more information.

  • 11. Operation Modes
    GREMSY S1 HAS 2 OPERATION MODES

    LOCK MODE: is a stabilization mode where the camera maintains orientation independently of the rest of the gimbal and the orientation can be changed by an external control signal from remote control.

    FOLLOW MODE: in this mode, the camera will mimic the operator’s movement and allows one person to control camera tilt and pan without using an external device like a remote control.

     
     
    GREMSY S1 Supports

    SINGLE OPERATOR: using FOLLOW mode.

    DUAL OPERATOR: a second operator can use a Remote Controller (SBUS, SPEKTRUM, PPM) to control gimbal’s movement.

     
     
    WORKING OPERATION

    GREMSY S1 has 2 working operations: Normal.

     
    Swithing Between Modes

    Using function button

    PRESS TIMES MODES
    Once time Turn motors ON
    2 times Lock mode
    3 times Follow mode
    Hold 3 seconds Turn motor OFF
    4 times Calibrate Gyros
     
     

    Using mode channel on remote control

    POSITIONS MODES
    High Follow mode
    Motors ON
    Midle Lock mode
    Motors ON
    Low Motors OFF
     
     
     

    Using software/application

    If there is a remote control signal, changing modes or turning motors on/off by other methods such as using the function button or software will not take effect because the remote control signal has the highest priority and override the command.
     
     
  • 12. Installing Software / App

    Mobile apps are available in App Store and Google Play

    App name: gTune

    Searching: “gremsy gtune”

     

    Desktop software

    Download at:
    www.gremsy.com -> Support -> Product Support -> GREMSY S1

     
     
  • 13. Using USB/ BLUETOOTH Connection
    To configure and monitor data of Gremsy software/app either USB/BLUETOOTH connection is required.
     
     
    USING USB CONNECTION
    Make sure the Silab USB driver is already installed. The driver can be found at:
    www.gremsy.com -> Support -> Product Support -> GREMSY S1
     

    STEPS TO CONNECT:

    • 1 - Power ON the GREMSY S1.
    • 2 - Connect USB cable from gimbal controller to Mac/PC.
    • 3 - Run the gTuneDesktop software.
    • 4 - On Connection Tab, select the Serial option.
    • 5 - Select the correct COM port in the list.
    • 6 - Click on the “Connect” button.
     
     
    USING BLUETOOTH CONNECTION
    STEPS TO CONNECT:

    1 - Enable bluetooth adapter of mobile devices

    On Android: the OS will ask for Location Data permission for BLE scanning feature (updated by Google since Android 6.0).
    On iOS: the OS has issue with its Bluetooth adapter itself sometimes, user should check device’s quick settings and general settings to enable the adapter, the Bluetooth icon should appear on device’s status bar.
     

    2 - Turn ON the gimbal and run the app.

    The application still supports WIFI connection like older version. In the case the app is using WIFI as default, user can switch to bluetooth by the button on top-right corner. The app will memorize the selected connection for later use.

    After being accepted to use bluetooth, the app starts scanning for Gremsy bluetooth integrated gimbals.

    • - If only one gimbal is found, it will be connected automatically.
    • - If more than one gimbal are found, a list of gimbals will be shown to let user select the desired one.
    • - If no gimbal found, an error will be shown.
