Troubleshooting
Status LEDs
The Locked and Speed Cal status LEDs on the
SYNC peripheral 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 pe-
ripheral is receiving valid Video Ref signal. If
this indicator is not lit, check your video con-
nections and termination status of the Video Ref
connectors on the SYNC peripheral.
Incoming Time Field
The Incoming Time field in the Session Setup
window indicates whether or not the SYNC pe-
ripheral is receiving positional reference. If this
field appears to be inactive when inputting
timecode to the SYNC peripheral, check your
hardware device settings, serial connection to
your computer, and your software settings.
Lost Communication
If Pro Tools loses communications with the
SYNC peripheral, a dialog appear asking you
whether you want to switch to MTC (if available)
or continue trying to locate the SYNC periph-
eral. If you see a “lost communication” dialog,
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 pe-
ripheral stops:
Use MTC
Click this button if the SYNC periph-
eral is unavailable, to switch to any currently
connected MIDI interface for MTC synchroniza-
tion. This option requires a compatible device
that supports MTC conversion, and that is al-
ready connected to your CPU and enabled.
Keep SYNC
Click this to leave the session con-
figured for the SYNC peripheral, or to continue
searching for the SYNC peripheral to re-estab-
lish lost communication.
Ref Present indicator (Session Setup window)
In Pro Tools HD software, these indicators
are also displayed in the Transport and Edit
windows. For more information, see “Sync
Status Indicators in the Edit Window” on
