Resetting 

Pushing the button on the front panel for about 10 seconds resets the USB hub to factory settings. The hub 
then restarts. The ports and multiplexers will be switched accordingly. This must be followed by the 
corresponding command. If the button lock is active, this function is not possible. The factory settings 
include: 

 

Normal mode after power on 

 

No exceptions for ready mode 

 

After ready mode, restore the state from before ready mode 

 

All USB ports are standard ports (SDP) 

 

Current limitation of all ports is 2.5A 

 

Connection detection for USB devices is enabled 

 

The button is unlocked. 

 

All USB ports are off after the USB hub is turned on 

 

All relay multiplexers are on after the USB hub is turned on 

 

The recognition number is not changed 

 
All USB ports are turned off by a reset. Disconnect all connected storage media from the operating 
system beforehand. 
The relay multiplexers will all be turned on. Disconnect any connections for which this is not desired.
