Troubleshooting
Status LEDs
The Locked and Speed Cal status LEDs on the
SYNC HD front panel and in the Session Setup
window may help you isolate potential problems.
Ref Present Indicator
The Ref Present indicator in the Session Setup
window indicates whether or not the SYNC HD is
receiving valid Video Ref signal. If this indicator is
not lit, check your video connections and termina-
tion status of the Video Ref connectors on the
SYNC HD.
Incoming Time Field
The
Incoming Time
field in the Session Setup win-
dow indicates whether or not the SYNC HD is re-
ceiving positional reference. If this field appears to
be inactive when inputting timecode to the
SYNC HD, check your hardware device settings,
serial connection to your computer, and your soft-
ware settings.
Lost Communication
If Pro Tools loses communications with the
SYNC HD, a dialog appears. If you see a “lost
communication” dialog, check power, serial, and
other connections.
Lost Communication Dialog
The Lost Communication dialog provides the fol-
lowing options for re-establishing communication
with the SYNC HD:
Use MTC
Click this button if the SYNC HD is un-
available, to switch to any currently connected
MIDI interface for MTC synchronization. This op-
tion 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 communica-
tion.
Synchronization Accuracy
If you are noticing drift or lack of accurate syn-
chronization between your devices, check the fol-
lowing:

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.
