Troubleshooting
Status LEDs
The status LEDs (LOCKED and SPEED CAL) on
the SYNC HD front panel and in the Session
Setup window may help you isolate potential
problems.
Use the Incoming Time field in Pro Tools
Session Setup Window as a Reference
The Incoming Time field in the Session Setup
Window indicates whether or not the SYNC HD
is receiving positional reference. If this field ap-
pears to be inactive when inputting time code to
the SYNC HD, check your hardware device set-
tings, serial connection to your computer, and
your software settings.
Lost Communication
If Pro Tools loses communication with the
SYNC HD, a dialog will appear asking you
whether you want to switch to MTC (if avail-
able) or continue trying to locate the SYNC HD.
If you see a “lost communication” dialog, first
check power, DigiSerial, and other connections.
Lost Communication Dialog
The Lost Communication dialog provides the
following options for re-establishing synchroni-
zation when communication with the
SYNC HD stops:
Use MTC Click this button if the SYNC HD is
unavailable, to switch to any currently con-
nected MIDI interface for MTC synchronization.
This option requires a compatible device that
supports MTC conversion, and that is already
connected to your CPU and enabled.
Keep SYNC Click this to leave the session config-
ured for the SYNC HD, or to continue searching
for the SYNC HD to re-establish lost communi-
cation.
Synchronization Accuracy
If you are noticing drift or lack of accurate syn-
chronization between your devices, check the
following:
‹
If your system locks up in the wrong place,
make sure you have set the correct frame rate
and format (NTSC or PAL) on all your devices.
‹
If your system locks up in the correct location,
but drifts, check your clock signals and settings.
