Crystal Vision Introduction
18/02/03 Page 3
1 Introduction
The ADC104 series of 10-bit analogue to digital converters are designed to convert
RGBS/YUVS signals to SDI serial digital video.
The range consists of the ADC104F which fully meets ITU 601 specifications for
component video filtering, the ADC104N which nearly meets the ITU 601 specification
and the ADC104FK, designed for use with graphics keys and which accepts only a Y and
sync input. The ADC104F and ADC104FK also provide eight test patterns.
The ADC104 10-bit analogue to digital converters
The common features are as follows:
•Timing from external analogue reference or syncs on Y or Green
•Horizontal position adjustment
•Enable or disable vertical blanking
•Enable or disable 525 line setup on Y
•Select normal N10 or ‘Betacam’ chrominance levels
•High quality digital clamp
•Manual or automatic 525/625 line standard selection (jumper selection.)
•GPI, Active Remote Panel, Statesman and board edge control
•Fine horizontal picture position (+/- 100 ns) adjustment available in either local or
remote mode.

Using chroma levels
The ADC104F supports ‘normal’ EBU/SMPTE N10 levels, which have been selected as
the analogue equivalent of SDI levels, and ‘Betacam’ levels, which may be met with early
recordings and/or equipment.
The N10 levels are based on 100% bars as its maximum signal, whilst Betacam levels
were based on 75% bars.
The following table describes expected input levels for 100% bars for the available
settings:
Input SMPTE/EBU N10 ‘Betacam’
RGB 625: 3x700mV video, 300mV sync Not applicable
Y U V 625/525: 700mV Lum, 2x350mV UV,
300mV sync
625/525: 700mV Lum, 2x350mV UV,
300mV sync
Y U V +

714.3mV (max) 53.55mV (min) Luma, 2
x 350mV UV, 285.7mV sync
714.3mV (max) 53.55mV (min) Lum, 2
x 467mV UV, 285.7mV sync.
Note: The Betacam chroma levels control has no effect on RGB inputs.
The facility to apply setup compensation in 525 is provided to cater for situations where
NTSC has been decoded with from a source that has had +7.5% setup applied to the
luminance.
Rear connector options
The ADC104 is a single height module and will fit into all Crystal Vision rack frames.
Three rear connectors are available, the RM01 providing two outputs, the RM02
providing three outputs plus a sync loop-through output and the RM18 which provides
four outputs and a sync loop-through output.
For frame packing density with the available rear connectors, refer to the Specification
chapter.

2 Using Statesman
The Crystal Vision Statesman PC control software is designed to control a range of
Crystal Vision modules via serial control from a PC.
Statesman provides a user friendly means of configuring and operating Crystal Vision
modules with the benefit of see-at-a-glance status monitoring.
The main Statesman application communicates with each module in a frame through an
active control panel. An active panel must be fitted to allow for Statesman control.
2.1 Installation
Minimum pre-requisites:
•Windows 98, NT4 with SP 5 or higher, Windows 2000, or Windows XP
•A parallel port dongle supplied with the Statesman software package
•An RS422 serial connection from the host PC to the Remote 2 connector of an
FR2AV Crystal Vision frame and at least one Statesman compatible module
•An active control panel MUST be fitted to the frame with version 1.5 or above
firmware
•An optional RS422 to RS232 converter if the PC has no RS422 ports
Installing Statesman
•To view all application windows, set graphics resolution to at least 1024 x 768
•Remove any previous version of the Statesman software using the Add/Remove
Programs application in the Windows Control Panel
•Ensure that the Statesman dongle is fitted to the parallel port of the host PC
•Insert the Statesman CD and the installation should start immediately – if it does not,
run the setup.exe file on the CD
•Obey any installation program prompts and restart the PC when prompted
Running Statesman for the first time
Statesman may be run from the Crystal Vision programs folder via the Start menu or by
double-clicking on the Statesman.exe file in the installed program directory (default is
C:\Program Files\CrystalVision).
When the program runs it should automatically detect any Statesman compatible modules
in the connected frame or frames and display them in the main application left hand
explorer-style window.

ADC104OperationalManualV3_2 Crystal Vision
Page 619/09/05
2.2 Statesman operation
The initial view will show an explorer style view of the connected frames and modules.
Open any frame by clicking on the ‘+’ sign or by double clicking on a frame. Installed
modules should be shown with module icons. Frame and module icons can be named as
desired by right-clicking or using the edit menu.
Double-clicking on a module will enable the display of the main application menu.
The Statesman ADC104F main application window
The menu display is repeated for convenience to allow dual-module display, dual-control
display of modules with duplicate signal paths or to allow two functions to be viewed at
the same time.
Note: Features and controls that are inappropriate in certain modes or mutually exclusive with
other controls will be automatically ‘greyed out’ to indicate that they are currently
unavailable.
Warning: Ensure that DIL lever 10 is set for in the DOWN position for Statesman control. A
message will appear to indicate that Statesman controls may be overridden by the card
edge if the ADC104 is set to local mode (DIL lever 10 UP)

4 Card edge operation
Although, the ADC104 may be operated through a remote interface such as the Active
Control Panel or Statesman, all functions can be accessed using card edge controls.
4.1 Card edge controls
The front edge of the card provides LED status and power rail monitoring, menu
selection, rotary set-up control and a ten-way DIL menu selector.
Card-edge menu selection is only available when DIL lever 10 is in the UP position.
The ten-way DIL switch selects available menus, whilst the Adjust/Select control is used
to select the required value or parameter.
Hpos fine
This is a multiturn potentiometer which allows fine adjustment of horizontal picture
position relative to in incoming syncs.. The adjustment range of this potentiometer is
approximately +/- 100 ns.
Shaft Encoder
The shaft Encoder is a rotary control labelled Adj/Sel and is used in combination with the
10 way DIL switch to adjust various parameters when setting up the board. It is only used
in local mode. It should be noted that the same parameters can also be adjusted from
Statesman or by the shaft encoder on an active remote control panel while in remote
mode.
In all cases the values set are retained through power down, and restored when the unit is
powered up.
Note: Selections made with levers 1 to 9 only apply when lever 10 (Rmt) is in the up position.
When lever 10 is down, the sections for levers 1 to 9 are determined by Statesman or the
settings from the active control panel.
