Chromatte™ Advanced Chroma Keyer

You may install one Chromatte™ Chroma Keyer to each M/E to add 
internal 4:2:2 chroma keying functions to Keyer 1 and Keyer 2. Each option 
includes a Chroma Key Carrier Module with a mezzanine module. The 
Chroma Keyer for M/E 1 slides into slot A3 and the M/E 2 Chroma Keyer 
slides into slot A16. To configure your Keyer option refer to the menus for 
the Chroma Keyer in Section Three of the Operators Manual. Any serial 
digital input may be used for 4:2:2 chroma keying from the key bus. Analog 
component video may be used for 4:4:4 chroma keying with the Analog 
Component Chroma Keyer Input Modules option. There is a separate front 
panel gain control for each of the input BNC connectors. 

The Borderline® option consists of one mezzanine module for one keyer. 
This option module mounts on the Keyer Carrier where the Borderline is 
desired. Up to four Borderline options may be installed on the Keyer 
Carriers; one for M/E 1 Keyer 1 (Slot A5), M/E 1 Keyer 2 (Slot A6), M/E 2 
Keyer 1 (Slot A13), M/E 2 Keyer 2 (Slot A14).

To install a Borderline Module, 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 

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.
