Precautions for connection
Notice
•
When connecting 5 or more HDD extension units (with 2 HDDs mounted on each unit) to the digital recorder, you are
recommended to use USB cable as illustrated below to prevent recognition error of digital recorder due to different
start-up times among HDDs.
Furthermore, before you start operation or when the power restores from a power failure, check that the HDDs are
recognized correctly even when a small number of HDD extension units are connected.

Tips
•
The available number of HDD extension units to be connected varies depending on the recorder connected. Check the
specification of the recorder.
•
You cannot connect 6 or more HDD extension units in series using serial bus.
•
The number of serial bus ports varies depending on the digital recorder connected. For stable recording, it is
recommended to use the ports of the recorder as many as possible to avoid branch connection of the extension units.
