• 07. HDMI Hyper Quick Release
  Mounting Hyper Quick Release

  Using 32mm square M3 pattern to mount the top part onto the frame or damping isolator.

  

   

   

  Connect

  STEP 1: The marks on the top part and bottom part must be aligned. The button on the ring should be aligned with the unlocked icon as shown in the first picture.

  STEP 2: Keep everything aligned and attach the bottom part to the top part.

  STEP 3: Rotate the ring clockwise until hearing a snap, the button should be automatically popped out and aligned with a locked icon.

  

   

   

  Disconnect

  STEP 1: Press and hold the button.

  STEP 2: Rotate the ring counterclockwise.

  STEP 3: When the button aligns the unlock icon, the S1 can be detached from the top part of Hyper Quick Release.

  

   

   

   
• 08. Powering Up The GREMSY S1

  After connecting to the power supply, the gimbal will perform a series of alignments, self tests, which last about 2 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 Hyper Quick Release is mounted to the drone and its power port is already connected to the power supply correctly. Next, let’s mount the gimbal to the Hyper Quick Release, it will be automatically powered up.

   

  Step 2

  Wait about 2 seconds, do not touch the gimbal or camera.

   

  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.

• 10. 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.

   

   
• 11. Working Operation

  GREMSY S1 has 2 working operations: Normal and Inverted.

  

   

  After powering up the gimbal , it will automatically detect if the gimbal is in inverted operation or normal operation based on pan motor position.

  

  During working, switching to another working operation made easy by changing pan motor position, the gimbal will automatically detect new types of working operation.

   

   

   
• 12. Swithching 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

  

   

   

  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.

   

   
• 13. 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

   

   
• 14. USING USB/ BLUETOOTH CONNECTION
  To configure and monitor data of Gremsy software/app either USB/Wi-fi 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 will sometimes have issues with its Bluetooth adapter. Users should check the device’s quick settings and general settings to enable the adapter and the Bluetooth icon should appear on the device’s status bar.
  • 2 - Turn ON the gimbal and run the app.
    After switching to Bluetooth, the app will begin scanning for Gremsy Bluetooth integrated gimbals.
    If only one gimbal is found, it will be connected automatically.
    If more than one gimbal is found, a list of gimbals will be shown to allow the user to select the desired one.
    If no gimbal is found, an error will be shown.
