REAR PANEL OVERVIEW
Figure 2-1 shows the rear panel of the HD9626DSK high definition keyer unit. Sections 2.1.1 to 2.1.5
describe the specific video and control signals that should be connected to the Downstream Keyer unit.
2.1.1. HD SDI Digital Video Connections
A and B:
These BNC connectors are the program HD SDI inputs to the keyer unit.
FILL and KEY:
These BNC connectors are the key and fill HD SDI inputs to the keyer unit.
PREVIEW OUT: This output BNC connector is the serial component SMPTE 292M preview video
output from the keyer unit. This preview output connector is normally connected to
an HD SDI preview monitor. This output is not bypass protected.
PROGRAM OUT: This output BNC connector is the serial component SMPTE 292M program video
output from the keyer unit. Connect this output to the next video device in your
output path. When the optional bypass relay is fitted (+ HBP option) this output is
protected by a bypass relay to the adjacent A input BNC. When the bypass relay is
activated on power loss to the keyer, the HD SDI PROGRAM OUT BNC will be a
direct relay connection to the A BNC.
2.1.2. Reference Video Connections
REF IN:
This is a 75 ohm terminated input for connecting an analog video or tri-level sync
(high definition units only) reference. Connect the REF IN connector to the reference
input sync. The REFERENCE menu is used to select the correct type of video
reference being used.
2.1.3. Serial I/O Connections
UPGRADE RS232 (A): This 9 pin female 'D' connector provides an RS-232 serial interface for
connection to a computer and is used for firmware upgrades to the HD9626DSK.
The pin definitions are shown in Table 2-1. See section 5.2 for more information on
upgrading firmware.
