5.07.1 Using USB 2.0 HUB
I’s allowed to use USB 2.0 HUBs in cascaded connection to visualize more axises with same PC. Tipical connection
available between PC and NTT 240/460 drive, using USB HUBs, is shown below:

NOTES:
•
Not insulated connection: USB comunication ground and 0L drive ground are equipotential. Maximum
permitted voltage against Power Earth (PE) is 50V.
•
It’s strongly recommended to use USB shielded cables, whose lenght is less than 3m for single drive or
less than 1m for each drive connected to an USB HUB.
•
Keep USB comunication cables far from power and feedback cables.
•
It’s recommended to use shielded HUB with active supply if long distances are required.
•
Maximum number of installable USB devices is 128, but real displayable number is related to PC
hardware and used operating system.
•
It’s possible to connect all other H.D.T. drive families, that support USB, to the same HUB.
