Common Questions:

What Does Uni-Directional Mean?

Uni-directional cables communicate data and commands bi-directionally, but necessitate that one device acts as the host (computer) to the connection and the other device as data source (camera). This allows for the most efficient and reliable method to transfer large data files. The devices will be able to fully communicate with each other, as happens with bi-directional cables. There are multiple communication ‘lanes’, so camera control can occur simultaneously as the images transfer. This 31 ft cable is specialized to isolate the data transfer direction for maximum efficiency and reliably.

How does the 1.5A downstream charging work if there is no PD in this cable?

The USB 3.2 standard has two methods for transferring power. All USB protocols have a built-in method for transferring (relatively low) levels of power. Just as the USB standard stipulates transfer speed, it also stipulates power draw as part of the standard. In the case of 3.0 and above, that is 5V 1.5A.

The USB 3.2 standard introduced a secondary (parallel) method for transferring power called Power Delivery (PD). This method allows for a much higher levels of power to be transferred (along with the traditional, relatively lower power mentioned above). PD can allow for up to 240W of power to be provided. This Power Delivery feature is known to cause instability in certain types of connections, including tethered connections. For this reason, the Power Delivery feature has been removed from the 31’ cable in order to provide the most stable connection possible. The built-in low-level (1.5A) power provision of USB 3.0 and above, remains part of the cable.
