Using FireWire and USB Devices With The Tempo Trio
16
Known Issues and Advice
FireWire and USB interfaces have many technological advantages over older inter-
faces such as serial and SCSI, not the least of which is hot-plugging capability.
However, there are some limitations you should be aware of, and some advice we
have listed here. Refer to the peripheral manufacturers’ web sites and user’s guides
for more specific information.
•
Many peripherals require additional drivers and application software to
operate or have full functionality
. Software should be included with the
device, or available to download from the manufacturer’s web site. Check the
peripheral’s user manual for information about necessary software.
• Disconnecting USB or FireWire peripherals (including external storage devices,
cameras, memory card readers, printers, etc.) while they are transferring or
receiving data, may result in damage to the file(s) being transferred or cause
your system to hang.
• Always “stop”, “unplug”, or “eject” any drive connected to the USB or FireWire
ports before disconnecting it from its cable or the Tempo Trio card.
• Remember to connect external power supplies to the peripherals that require
them. Although many peripherals may draw power directly from the Tempo
Trio card, other devices require an external power source.
• When a USB 2.0 peripheral is connected to a USB 1.1 peripheral, which is in
turn connected directly to the Tempo Trio, the USB 2.0 peripheral will operate
at USB 1.1 speeds. Connect USB 2.0 and USB 1.1 devices separately to the
Tempo Trio’s two USB ports.
• Should you need to connect USB 2.0 peripherals to a hub, be sure to use a USB
2.0 hub; USB 2.0 peripherals connected to a standard USB hub will operate at
USB 1.1 speed.
• When transferring data from a digital video camera using a FireWire port on the
Tempo Trio, we do not recommend using another FireWire device at the same
time.
• Do not connect FireWire devices in a loop, nor terminate a FireWire chain;
there are no terminators or ID settings required for any FireWire device.
