7714HDC High Quality Down Converter
OSD/GLCK: When the OSD/GLCK BNC menu setting is set to OSD, this BNC connector is used to
output the downconverted input video with on screen display menus (OSD) superimposed
over the video as serial component video compatible with the SMPTE 259M standard or as
analog composite video depending on the setting of jumper J26. It can also be used as a
genlock input reference (see section 2.2).
2.2.

GENLOCK REFERENCE

For proper synchronization of the output video, the 7714HDC Down Converter must be locked to a
genlock signal of the output video frame rate.
OSD/GLCK: When the OSD/GLCK BNC menu setting is set to Genlock, this BNC is used for connecting
a video or tri-level sync reference and is auto-detected by the module. The output video
can be timed with respect to the genlock video using the H Phase Offset and V Phase
Offset menu items. (See section 6.3.1) When no Genlock is provided, the output video is
timed with respect to the input video. To use this BNC as a genlock input, jumper J26 must
be in the composite position. Jumper 21 selects the desired termination. (75 ohm / Hi-Z)

AES INPUT AND OUTPUT AUDIO CONNECTIONS

Four unbalanced AES input and outputs are provided on a HD DB-15 connector labeled AES I/O. These
inputs and outputs are for unbalanced AES signals conforming to SMPTE 276M. The user can select
whether audio from the four AES input pairs, or from 2 groups of embedded audio is re-embedded on the
output video. The transferred audio is also output as four AES pairs. Figure 2-1 shows the pinout of the
DB-15 connector.

Shell
The 7714HDC is shipped with a breakout cable for the 15 pin D connector (Evertz Part # WPAES8-
BNCM-6F) which can be used to facilitate wiring the audio and GPI connections. The pinout of the cable
is shown in Table 2-2.
