USB Connection

Top  Previous  Next

Power:

 

DV3100, DV3109, DV3200, DV3209, DV3409, DV509, DV518:

Plug DigiView directly into a USB port on your PC or into a POWERED HUB. If using an external hub, you should use one with its own power supply. Most bus-powered hubs can not provide enough power to operate DigiView.

 

DV3400, DV3500:

Powered by an external power supply, so USB power is of no concern.

 

 

Speed:

 

DV3100, DV3109, DV3200, DV3209, DV3400, DV3409, DV3500:

You will experience better performance on a 2.0 port (High Speed @ 480 Mbps), but a 1.1 port is sufficient.

 

DV509, DV518:

You will experience the best streaming performance on a 3.0 port (SuperSpeed @ 5 Gbps). However, these units are compatible with 2.0 ports (High Speed @ 480 Mbps). You can still stream at most sample rates using a 2.0 port unless the data rates are too high. If the streaming terminates early the guaranteed minimum is still captured in the large Hardware buffer.

 

 

Connection Quality:

 

Preferably, use a high-speed USB port located directly on the motherboard at the rear of the computer or a port anywhere on the computer case that utilizes a high quality cable internally. If you use a different USB cable than the one provided with the unit, it should match the full rated speed of the USB connection to prevent communication errors or loss of data.
