Parameters and Values When configuring a
SYNC peripheral with the Set, Run/Stop and
other parameter controls, the LED display shows
parameter names, values, and other data.
Positional Reference Switch
This switch selects the positional reference
source, as indicated by the Positional Reference
LEDs. Choices include LTC, VITC, Auto Switch
Bi-phase, and Generate.
In Auto Switch LTC/VITC mode, both the LTC
and VITC LEDs light while the SYNC peripheral
determines which source it will use. Either the
LTC or the VITC LED will remain lit to indicate
the chosen positional reference.
Frame Rate Switch
This switch selects the time code frame rate and
format (drop-frame or non drop-frame). The ac-
tive choice is displayed by the Frame Rate and
DF (drop frame) LEDs.
Frame Rate LEDs and DF Indicator
These display the current SYNC peripheral
frame rate: 30, 29.97, 25, or 24 fps are indicated
by four green LEDs. The DF LED indicates drop-
frame (lit) or non drop-frame (unlit). The 24 fps
LED flashes to indicate 23.976 fps.
Status LEDs
These LEDs show the current state of the SYNC
peripheral in relation to clock references. Indica-
tors include:
Locked This LED lights solid green when the
SYNC peripheral is locked to the selected clock
reference.
• SYNC HD: The Locked LED flashes yellow
if the selected clock reference source is
missing or out of lockable frequency range.
• SYNC I/O: The Locked LED flashes green if
the selected clock reference source is miss-
ing or out of lockable frequency range.
Speed Cal (Speed Calibration) This LED lights to
indicate the status of the clock reference:
• Yellow Solid: SYNC peripheral is locked and
that the clock reference is within 0.025% of
the expected rate
• Yellow Flashing Fast: SYNC peripheral is
locked, but the clock reference is between
0.025% and 4% faster than the expected
rate
• Yellow Flashing Slow: SYNC peripheral is
locked, but the clock reference is between
0.025% and 4% slower than the expected
rate
• Red Flashing Fast: SYNC peripheral is
locked, but the clock reference is more than
4% faster than the expected rate
• Red Flashing Slow: SYNC peripheral is
locked, but the clock reference is more than
4% slower than the expected rate
• Unlit: SYNC peripheral is not locked to the
chosen clock reference
Remote Mode This green LED lights when the
SYNC peripheral is set to Remote-Only/Front
Panel Lockout mode. While this LED is lit, the
front panel switches will have no effect.
