Trouble Shooting
Q: There is no output from my card when in desktop mode.
A: Go to the Apple menu and choose System Preferences. Click on the
Blackmagic DeckLink icon. Ensure that “Video Desktop” option is set to
“Enabled” and then restart the Mac. You should now see your extended desktop
on your broadcast monitor. If it still does not appear, go to the /Applications/
Utilities folder and launch Disk Utility.
Select your startup hard disk and then click on “Repair Disk Permissions.”
A progress bar will draw across your screen and then disappear. This will
usually take 5 or 10 minutes and then you can restart your Mac. Now see
if the desktop displays on your broadcast monitor. If not, please contact
macsupport@blackmagic-design.com.
Q: I can’t get machine control of my tape deck.
A: Make sure that the deck you are using supports and is connected via the
Sony RS-422 serial protocol. DeckLink does not directly support older RS-232
serial devices.
Some low-cost decks, such as the Sony UVW1400a still use RS-232. Final Cut
Pro can provide deck control via RS-232 with the addition of a Keyspan “High
Speed” USB Serial Adapter http://www.keyspan.com/products/usb/USA19W.
You will need to congure the RS-232 protocol by going to the Audio/Video
Settings, in Final Cut Pro, and then click on Device Control Presets. Edit each
preset for which you want to use RS-232. This solution works ne if you have to
use RS-232.
If using a Panasonic deck, you may need to use the deck’s USER Menu to
change the “ID SEL” to “other”, to make it compatible with the Sony RS-422
deck control protocol. “ID SEL” is usually USER Menu item number 202.
Q: Can I monitor audio from my Mac’s internal speaker?
A: Yes you probably can, however we do not recommend it. This is because
the Mac system clock and the DeckLink’s clock are different. If you monitor
audio through your Mac’s internal speaker, the audio is likely to be out of sync
with video. Furthermore, audio might stop working for no apparent reason. We
strongly recommend using the SPDIF output connectors from the DeckLink
card, or the audio output from your deck, to monitor your audio.
