VIDEO SYNC CONNECTIONS

Connect a video sync source, such as blackburst, to
the VIDEO REF IN jack (Figure 3-8). This input
accepts either a Bi-level (SD) sync source or a
Tri-level (HD) sync source. The HDX-SDI can
resolve to a VIDEO REF IN signal only when it is in
Playback mode, or when it is capturing SDI. When
capturing other sources, it genlocks to the current
video source, or its own Master (Internal) clock.
For further information, see "Capture Clock
Source" on page 35.
Video ref termination and "thru"
The HDX-SDI lets you daisy-chain the VIDEO
REF signal to another video device using the
THRU jack below the VIDEO REF jack. If you
connect a device to the THRU jack, set the
termination switch (Figure 3-8) to the THRU
position.
If the HDX-SDI is the only device (or the last
device in a daisy-chain), set the termination switch
to the 75Ω TERM position. This is crucial for
successful genlock.

TIME CODE CONNECTIONS

Connect any time code source, such as the time
code output from a camera or VTR, to the LTC IN
jack (Figure 3-8). If you wish to transmit time code
from the HDX-SDI to another device, connect the
HDX-SDI LTC OUT to the time code input on the
other device. See "Setup tab" on page 35 and
"Playback tab" on page 38 for information about
managing the HDX-SDI's time code features.

RS-422 MACHINE CONTROL

If you have a VTR or other device equipped with
Sony 9-pin compatible machine control, and you
would like to control it using Final Cut Pro's
machine control features, connect its RS-422 port
to the HDX-SDI's RS-422 port (Figure 3-9). Also
see "Device control" on page 49.
