There are a couple of different USB connectors that you could use while working on a SlingStudio production: one USB connector type with the SlingStudio unit itself, and one type with the SlingStudio CameraLink product.
The SlingStudio unit
The SlingStudio unit itself has a port labeled USB-C.
You can use this port to connect USB-C type storage devices directly.
Otherwise, this port should only be used with the SlingStudio USB-C Expander product for USB 3.0 storage units or other USB devices.
Note: Other USB-C extenders may not be optimized for multi-camera video recordings.
Once you connect a SlingStudio USB-C Expander to the SlingStudio unit’s USB-C port, you can then connect up to two USB 3.0 devices using a standard Male USB Type-A connector, which looks like this:
These USB 3.0 are helpful for connecting external storage devices to your SlingStudio unit. Do not connect more than one unpowered USB storage device to the SlingStudio USB Expander, as there might not be sufficient USB voltage available. If you need to connect more than one USB storage device, then use storage devices that are powered externally (usually with an AC wall adapter).
Note that the SlingStudio USB-C Expander also offers an Ethernet port.
The SlingStudio CameraLink device
The SlingStudio CameraLink has a port for a Micro USB Type-B connector, like this:
The CameraLink only uses its USB port so that you can connect it to a USB battery charger. It does not use its USB port for any data transmission purposes.
Be sure to connect your CameraLink to a USB battery charger that outputs at least 10 watts (5 volts with at least 2 amps). USB chargers that output less than 10 watts can cause the CameraLink battery to discharge faster than it is charging when you are streaming video.
