Installation
The parameters for various Chroma Keying functions must be defined in the main
menu panel. These menus appear under the Chr Key button. Refer to the Model
4000 User’s Guide (TP0790) and Operation Reference (TP0764) Manuals for
detailed information.
BORDERLINE Key Edge Generator Option
The BORDERLINE option consists of one mezzanine module (064909) for each
keyer. This option module mounts on the Keyer Carrier where the Borderline is
desired. Up to eight BORDERLINE options may be installed on the Keyer Carriers;
one for M/E 1 Keyer 1 (Slot C6), M/E 1 Keyer 2 (Slot C7), M/E 2 Keyer 1 (Slot C11),
M/E 2 Keyer 2 (Slot C12), M/E 3 (4000-3 only) Keyer 1 (Slot B7), M/E 3 (4000-3
only) Keyer 2 (Slot B8), DSK Keyer 1 (Slot C14) and DSK Keyer 2 (Slot C15).
To install a Borderline mezzanine, remove the designated Keyer Carrier carefully,
and place it on a static free surface. The Borderline Mezzanine installs in the top
location of the module above the Keyer Mezzanines as illustrated in
Figure 2-29 .
1. Line up the four 50-pin connectors on the Borderline mezzanine with the
matching connectors on the Keyer Carrier. Be sure the pins are lined up
properly before seating the mezzanine (look between the mezzanine and the
Carrier). Push down firmly to seat the mezzanine to the Carrier. Check that no
pins are bent or outside of the connectors.
2. From the solder side of the Carrier, attach the mezzanine to the module; install
the four screws into the metal spacers on the mezzanine, and carefully reinstall
the Keyer Carrier into the frame in its proper slot location.
NOTE: For best mechanical fit, Mezzanine modules should always be removed by
unscrewing from the solder side of the Carrier, not from the component side of the
Mezzanine.
