having to do with capture, playback, sync and
other aspects of HD Express operation. MOTU
Video Setup is engineered to detect problems and
report them in the Status area. Most common
issues can be resolved by following the instructions
given by the Status display.
FREQUENTLY ASKED QUESTIONS
I see the following error message in Final Cut Pro:
Unable to locate external device. Why?
If you see the error message below when operating
the HD Express with Final Cut Pro, it means that
Final Cut Pro has lost communication with the
HD Express hardware. Check your HD Express
hardware and cable connections, and then restart
your Mac.
Figure A-1: If you see this message check your hardware and cable
connections.
MOTU Video Setup cannot detect the HD Express.
Why not?
Is the HD Express connected to the PCIe card
adapter installed in a desktop computer? If so, did
the HD Express breakout interface get
disconnected or powered off while the computer is
still powered on? In this case, you need to shut
down the computer, plug in the interface, switch it
on and then power up the computer. The breakout
interface must remain connected and powered on
while the computer is running. The HD Express's
Auto On mode lets you leave the power switch on,
and the interface will power up and power down
with your computer. See page 5 for details on Auto
On mode.
Connecting or powering gear during operation
It is not recommended that you connect,
disconnect, or power on/off devices connected to
the HD Express while recording or playing back
audio. Doing so may cause a brief glitch in the
audio.
The HD Express is having trouble genlocking to my
video deck.
Is the deck connected to a video output from the
HD Express? If so, it could be a clock loop
problem, where the deck is trying to resolve to its
video input, while the HD Express is trying to
resolve to video input from the video deck. See
"Master (Internal)" on page 28.
I experience glitching in my video signal when
switching between Capture and Playback.
See "Clock source when switching between
Capture and Playback modes" on page 28.
My reference monitor(s) connected to the
HD Express only displays single frames.
Make sure All Frames is selected in the
View>External Video menu in Final Cut Pro.
My reference monitor(s) connected to the

Make sure the Final Cut Pro MOTU RT Enabler is
