CHAPTER 2: CAPTURING ■

Free DV and Xpress Pro can poll the deck or camera to determine its model and

make automatically. There are times, however, when the Avid does not properly iden-

tify the deck or camera. Keep in mind that there are now many decks and cameras on

the market, and although the protocols are common, the controls are not.

The best thing to do is to go to your deck configuration settings and do it your-

self. To do that, first go to the Project window and click the Settings tab. Locate the

Deck Configuration Settings and double-click.

It might take a moment or two for the deck templates to load. The deck tem-

plates contain information about how to control the most commonly used decks. If

your deck is not among the templates, you can still use a generic template and config-

ure it for your deck.

If this is your first time using Deck Configuration (see Figure 2.32), click the

Add Channel button; the Channel Options appear. You can choose between Direct

(RS-422) and OHCI (IEEE 1394 or FireWire), which we mentioned before.

Figure 2.32 Deck Configurations box

On Windows machines, usually an RS-422–to–RS-232C adapter, such as

Addenda’s Rosetta Stone, is used for controlling the deck. The deck is therefore con-

nected to one of the two RS-232C serial ports built into your system. On Windows

systems, you must choose between the Com 1 and Com 2 RS-232C ports on the com-

puter.

On Mac systems, RS-422 control can be established, but it requires either a

third-party card (such as Gee Three’s Stealth card) or an adapter from USB to serial

(such as those made by Keyspan). A Mac serial–to–9-pin cable will also be required.

The Stealth card and many others like it will allow direct connection between the

RS-422 connector on the deck and the card on your Mac. The Keyspan adapter, which

is a less-expensive option, connects to any USB port and will control the deck directly
