Bi-Phase/Tach/GPI/Pilot
This is an accessory port for Bi-Phase, Tach, and
Pilot signals (specific cables are required for dif-
ferent applications). This connector is also used
for GPI input, output (including Fader Start),
and thru signals. This port handles up to 12 V
Bi-phase.
Refer to Appendix C, "Wiring Diagrams
and Pin Assignments" for wiring informa-
tion and other specifications for this port.
Video Reference In/Out
Video Ref In Receives a signal from an SD
(NTSC/PAL) or HD (tri-level or bi-level) video
source (such as a black burst (house sync) gener-
ator or a standard video signal) for purposes of
clock reference.
This port is configured as an un-terminated
loop-through. When you connect a signal to
this port, you must do one of the following:
• Connect a 75-ohm BNC terminator (included
with the SYNC HD) to the Video Reference
Out on the back panel
– or –
• Make sure another terminated video device is
fed from the Video Reference Out connector.

Video Ref Out A parallel, unbuffered connection
output for any video source connected to the
Video Reference In port. This port allows black
burst or other video reference to be passed to an-
other device, and continues to output whatever
signal is present at the Video Reference In port,
whether the SYNC HD is on or off.
If the SYNC HD is the last device in the
video sync chain, a 75-ohm BNC termina-
tor must be attached to this connector.
Host Serial Port
The Host Serial port is a bidirectional (in/out)
port to connect the SYNC HD to the DigiSerial
Port on a HD Core card. When not being used
with Pro Tools, the SYNC HD Host Serial port
can be connected to a standard serial port on a
supported computer to run the SYNC Setup soft-
ware utility (Windows only).
