VIDEO SYNC CONNECTIONS

Connect a video sync source, such as blackburst, to
the VIDEO REF IN jack (Figure 4-10). 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 38.
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 4-10) 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.

TIMECODE CONNECTIONS

Connect any timecode source, such as the
timecode output from a camera or VTR, to the LTC
IN jack (Figure 4-10). If you wish to transmit
timecode from the HDX-SDI to another device,
connect the HDX-SDI LTC OUT to the timecode
input on the other device. See "Setup tab" on
page 37 and "Playback tab" on page 40 for
information about managing the HDX-SDI's
timecode 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 Premiere Pro's
machine control features, connect its RS-422 port
to the HDX-SDI's RS-422 port (Figure 4-11). Also
see "Device control" on page 52.
