DV In/DV Out Cards
Avid Xpress DV supports the Open Host Controller Interface
(OHCI)-compliant IEEE
®
-1394 chip (based on Texas Instruments
™
technology). For the most up-to-date list, go to www.avid.com.
OHCI Chip - TI 1394 Integrated Circuit Device
The TI (Texas Instruments) OHCI chip is the only OHCI chip that Avid
has qualified to use with the Avid Xpress DV system. Avid will only
support, and highly recommends, the use of the TI 1394 Link and PHY
chip.
Installation and the OHCI Drivers
Avid Xpress DV does not use the default WIN2K OHCI driver, but uses
a custom OHCI driver. Whenever you connect a new camera or deck
(DV device) to the system via OHCI 1394, you have to link the device
with Avid’s custom OHCI driver rather than the default driver. There
are two scenarios under which you should follow this process:
• You have not previously connected a DV device.
• You have previously connected a DV device and used the
Microsoft
®
OHCI 1394 driver.
You can also link a DV device to a particular driver if you want to use
a driver other than the custom OHCI driver.
Linking the Driver to a New DV Device
To link with the correct driver if you have not previously connected
a DV device:
1. Start the Avid Xpress DV application before connecting the camera
or deck via the OHCI 1394 driver and turning it on.
2. Connect the DV device, and then turn it on.
