When the USB cable is disconnected, the drive connected via the USB port is removed from the Network bus list.
CONNECT 1 DRIVE VIA USB TO PC
A USB bus has no address-setting capacity and no bus name to configure. If connecting more than 1 drive through USB, the bus
name is auto-incremented in the MCT 10 Set-up Software Network bus list.
Connecting more than 1 drive through a USB cable often causes computers installed with Windows to throw an exception and
crash.
-
Only connect 1 drive via USB to the PC.
