Overview
The HD-8020 is a high quality 12-bit digital to analog converter that accepts HD SMPTE-292
and SD SMPTE 259M-C input signals and converts them to same rate and format analog video.
For HD signals the 8020 the user can select YPbPr or RGB outputs with embedded tri-level sync
or H and V sync on a five BNC interface.
For SD signals the 8020 can be configured to output Component, Composite and Y/C signals. In
component mode the user can select RGB or YPbPr in BetaCam(tm), MII(tm) or SMPTE/N10
levels.

How to Configure an 8020
Switch Bank 1 –Analog Output
The third switch bank controls the analog encoder’s configuration. Both the HD and SD analog outputs are
configured by these switches. Additional analog configuration is available using the interior switches as
described in the Internal Switch Setting section.
The SD analog output type is selected by the first three switches of S1.
Switch Bank 1 - Analog Output Configuration –SD Setup
S1-1 S1-2 S1-3 Function - SD Analog Configuration
ON ON ON SD Composite and Y/C
OFF ON ON SD YPbPr BetaCam(tm) levels
OFF ON OFF SD YPbPr MII (tm) levels
OFF OFF ON SD YPbPr SMPTE levels
OFF OFF OFF SD RGB levels
Switch Bank 1 - Analog Output Configuration - SD Setup Continued
S1-4 Function Color / Monochrome Mode
ON SD color ON
OFF SD color OFF –useful for driving B&W monitors
Switch Bank 1 - Analog Output Configuration - SD Setup Continued
S1-5 Function Setup Control for NTSC
ON SD Setup ON (NTSC signals only)
OFF SD Setup OFF
Switch Bank 1 - Analog Output Configuration - SD Color Bars
S1-6 Function Color Bars
ON SD Analog Color Bars ON
OFF SD Analog Color Bars OFF
Note: The 8020 will not output color bars unless an SDI input is present.

The last two analog output switches set up the HD color type (YPbPr or RGB) and sync type.

OFF HD Component RGB
Switch Bank 1 - Analog Output Configuration - HD Setup
S1-8 Function HD Sync selection
ON Embedded Tri-level
OFF H & V external
Sync can be either embedded on the HD video as tri-level or bi-level or as external H&V. To select bi-
level you must use the internal rotary switches and change the embedded sync type to bi-level. The default
embedded sync is tri-level and is on all three output HD channels (YPbPr or RGB).
If H&V external sync is selected, the embedded sync is removed for RGB signals and H&V are sent to the
H&V connections on the HD-15 connector.

Switch Bank 2 –Reticule Overlay
The second bank of switches control the reticule overlays. This overlay engine is very flexible and can be
user programmed with other aspect ratios via the internal rotary switches and saved in non-volatile
memory. This allows the creation of film aspect ratios or video aspect ratios specific to the project at hand.
Switch Bank 2 –Reticule Overlay - Output Enable
S2-1 Function
ON Enable overlays on analog outputs
OFF Disable overlays on analog outputs
The next switches define what type of overlay is to be used. Each type can be enabled or disabled
individually. The user can use the factory default settings or program their own and save those settings.
Use the internal rotary switches, defined in the next section to program the user settings. Place S2-6 to user
presets (ON). This feature gives a total of eight different overlays of which four can be used at one time.
Switch Bank 2 –Reticule Overlay - Overlay Type Selection
S2-2 S2-3 S2-4 S2-5 S2-6 Function
ON Center Cross Enable or User Preset
OFF Center Cross Disable or User Preset
ON 4 x 3 Safe Area Enable or User Preset
OFF 4 x 3 Safe Area Disable or User Preset
ON 4 x 3 Full Aperture Enable or User Preset
OFF 4 x 3 Full Aperture Disable or User Preset
ON 16 x 9 Safe Area Enable or User Preset
OFF 16 x 9 Safe Area Disable or User Preset
ON User Presets Enabled (internal switches to configure)
OFF Factory Defaults Enabled
The next switch setting selects white, blue, Green or black reticules. The overlay can be User programmed,
via internal switches, to be any color and saved as user default. This user color would be present when the
User Preset Enable switch (S2-6) is ON.
Switch Bank 2 –Reticule Overlay - Color Selection
S2-7 S2-8 Function
ON ON Reticule color is White or User Preset
OFF ON Reticule color is Blue or User Preset
ON OFF Reticule color is Green or User Preset
OFF OFF Reticule color is Black or User Preset

Internal Switch Settings
The 8020 has additional configuration controls via internal register rotary selection and input (up/down)
switches. To access these controls, disconnect power while removing the bottom cover and locate two
rotary switches (S5, S6) and two push button (S7-UP, S8-Down) switches and reapply power.
Default convention: Use S7 (UP) to increment or turn function on. Use S8 (Down) to decrement or turn
function off. On most functions, pressing both S7 & S8 (Up & Down) restores the default mode.
To save user settings, select 99 and press either the Up or Down switch.
