Instructions

- Assign a scene name for the stream before starting to stream.
- Further operating instructions can be found in the help function of the program or in the
support area of XSplit, as well as in the medium supplied with the stream (f. e. Youtube,
Twitch, etc.)
Stream with OBS
- Go to the website: https://obsproject.com/de
and download the “OBS Studio” software. Versions for MS Windows, Mac OS and
Linux are available. Please note the information in the download area for your respective
operating system version.
- Install the program on your PC.
- Depending on the software on your computer, the program may ask you to load and install
additional software components during the installation (Auto-Configuration Wizard).
These can also be installed later via “Tools -> Auto-Config Wizard”
- Mark your device (D720) via „Settings -> Audio“ and „Aux Audio Device“ as an
audio source.
- Then select your device (D720) as a video source via “Sources ->
+ (add, Video capture Device)”.
- Enter a name for the stream under “Scene Collection”.
- Test the stream for several minutes with an activated Grabstar PRO (in PC streaming
mode) under “Settings -> Output” and “Start Streaming” so check whether the stream
is stable over a longer period of time.
- The program is an open source program and constantly evolving. That is why you will
find current and detailed operating instructions in the help function of the program or
in the help area of OBS as well as in the medium supplied with the stream (f. e. Youtube,
Twitch, etc.).
6. Firmware-Update
- Copy the update file into the basic directory of an SD memory card or a USB storage
that you connect to the Grabstar PRO.
- Switch on the device. The upgrade window appears automatically if you have copied
the firmware to an SD card. For USB storage, manually select the firmware update
option in the main menu and start the update from there.
- Start with “Confirm”.
7. Error Notifications
No picture on the display
- Check the connection and output of the video source.
- If the video source outputs an HDCP-protected signal, switch off the HDCP (if possible).
- The display remains switched off during playback when the device is connected to a
monitor/TV via the HDMI output.
Device does not recognize storage medium
- The storage medium may not be formatted with FAT32, NTFS or exFAT, f. e. if it was
previously used in a digital camera. Format it using a PC with a compatible file system.
- You can formate new memory cards via the internal menu „format“. For formatting
high-capacity USB hard drives, we recommend using the freeware tool „Guiformat“ and
formatting the hard drive in FAT32 format.
Mac OS users must note that the exFAT and NTFS format cannot be used. Linux users
are also affected by this, but can use various solutions and tools on the Internet. The for-
mats mentioned here refer to a Windows client / computer.
Picture freezes while recording
- Press the On/Off button for 10 s and the device will restart.
No sound output
- Check whether the mute function is activated and if a sufficient sound level is set.
No files found for playback
This can be the case if you have uploaded files externally. Video files must be stored in
the folder “Video”.
External USB hard drive not working
- Only operate USB hard drives if the power supply of the Grabstar PRO is connected.
The battery may not be able to provide enough power in stand-alone mode. 3.5” hard
disks must be operated with their own power supply.
PC does not find the device as external storage
- Check whether the “PC storage mode” option is activated on the device.
PC does not find the device as a streaming source
- Check whether the option “PC streaming mode” is activated on the device.
- Check the USB-PC connection and on the PC (Control Panel -> Device Manager/
Manage Audio devices) whether the device is recognized and set as an external audio/
video device (D720). Often, especially with laptops, only the internal microphones/
cameras are set. The setting must then be changed manually. The selection is usually
also possible in the streaming programs.
Sound and images are not streamed synchronously / appear “jerky” on PC
- The hardware equipment (CPU, memory, sound and image hardware) cannot provide
enough performance. Use a current PC with sufficient hardware graphics accelerator
and current audio driver.
Sound and images are not reproduced synchronously on the Grabstar PRO
- This may be due to the internal conversion time required from high-resolution videos
to the screen size of the display. Therefore, avoid playing HD videos and use the HDMI
output.
8. Care and Maintenance
- Only clean the device with a soft, dry linen cloth. If the device is very dirty, the cloth can
be slightly damp. Do not clean the device with cleaning agents containing solvents. The
device must then be carefully dried with a cloth. Make sure that no moisture gets inside
the device.
- Do not interrupt the power supply or the connection to the data storage device during
the update.
- After a successful update, the device automatically restarts
