Crystal Vision Introduction
1 Introduction
The REFGEN is an analogue and digital black generator that will output both
an analogue and serial digital reference. The REFGEN may be operated in a
stand-alone free-running mode or when given an analogue input, an output
that is locked to the input but with up to a two field delay. A choice of a blue or
black output may also be selected.
REFGEN block diagram
The serial digital output has virtually no output jitter both when used with a
stable analogue reference and when used without a reference. The minimum
delay between the input reference and output is only 2µs.
The main features are as follows:
• Free running or timed to analogue input
• Selectable black or blue output
• Up to four simultaneous Serial Digital and four Composite outputs
• Output timing up to two field’s adjustment from analogue reference input.
• 50 ppm free running accuracy
• Flexible control
REFGEN is a 100mm x 266mm module that will fit in all the standard frames
and can be integrated with any boards from the company’s full product range.
Free running and synchroniser/delay modes
The REFGEN has two modes of operation, free running and synchroniser/delay.
REFGEN User Manual R2.0 3 11 January 2019

Crystal Vision Introduction
In synchroniser mode the unit takes its timing from the analogue external
reference and will automatically lock its output to this. It is then possible to
add a delay of between 0 and 2 fields in lines and pixels to the output
reference with respect to the external reference.
In free running mode the output reference is timed to an accurate on-board
clock generator.
Switching between free running and synchroniser mode is automatic when the
external reference is added or removed.

Crystal Vision Hardware installation
2 Hardware installation
The REFGEN analogue and digital black generator will fit into all Crystal
Vision rack frames. All modules can be plugged in and removed while the
frame is powered without damage.
Note: Connection information differs from the original REFGEN.
Rear modules and signal I/O
The 4U Indigo 4 frame takes up to 24 single height Crystal Vision modules, 12
single height modules fit in the 2U frame, six single height modules fit in the
1U frame and two single height modules fit in the 1U desk-top box.
Rear module connections with the RM01
The RM01 single height rear module allows maximum packing density but has
limited connections.
RM01 fits in all current frames Description

Rear module connections with the RM23
The RM23 single height rear module is useful in situations where only a digital
reference is required. A benefit of the RM23 is that it has an external
reference loop-through output that is not reliant on the REFGEN PCB so it
will still be present should the REFGEN be removed.

This operational guide assumes that the panel has been setup according to the
panel set-up procedure described in the Crystal Vision Control Panel manual.
Note: It is ESSENTIAL that the panel set-up procedure is followed and any old or
unknown passwords cleared prior to using the panel for the first time.
At power up, the two lines, 20-character screen will display ‘Crystal Vision’
followed by the firmware version number for the control panel. All eight
control panel keys LEDs will illuminate.

'Control Panel' then briefly replaces the version number display.
If the control panel firmware has been updated for Statesman control
(version 1.5.0 or higher), Statesman Mode will be entered and the message,
‘Press CAL to Exit’ will be displayed and the CAL LED will light.
Statesman mode is entered by default
To continue with control panel operation or configuration, press the CAL key
once. A second press of the CAL key will return to Statesman control.

Crystal Vision Using the active front panel
The control panel will display the name of the card that first responds to the
polling request together with its location number.
The location number consists of the frame number plus the card position in the frame.
Navigating the display
The functions assigned to control panel keys are:
• DEVICE – enters Device menu to select a card or show cards available / enters panel
set-up when held down during power up / shows frame status when pressed from
Statesman mode
• CAL – enters or leaves Statesman mode / enters panel diagnostics mode when held
down during power up / updates the display
• Asterisk – enters board rename menu from the Device menu
• F1 to F4 – soft keys, function assigned within each menu
• HOME – moves the display to the home menu
• ENTER – accept current selection
• Upward arrow – used to move up the menu structure / enter lock panel menu from
the Device menu
• Rotary control – shaft encoder used to select options or variable data
Note: Please refer to the Crystal Vision Control Panel manual for details of the
Panel Setup, Lock Panel and Diagnostic menus.
Selecting REFGEN
To select a particular card in a frame, press the DEVICE key to go to the
Device menu. The top line of the display will show ‘Available Cards X’, where
X is the number of cards that have responded so far to the polling request.
The available cards menu
Rotate the shaft encoder and the bottom row will display the successfully
polled cards by name and location or slot number.
In the example above, the card displayed is located in the first frame in slot
number 3.

4.1 Updating the display
The values displayed on an active front panel are only updated when an
adjustment is made and when changing menu level. If changes occur through
the use of card edge controls or other remote control, the text displayed on the
active front panel will not be updated immediately. If necessary, use the
upward arrow to leave and then re-enter a menu to update the display.
4.2 The REFGEN active panel menu structure
At any time the main top-level menu (Home) is obtained by pressing the
HOME key. From the home menu further selections can be made. Active
function keys are indicated by illuminated, integrated LEDs.
The main top-level menus for the REFGEN module are obtained by pressing
the F1- F4 keys from the HOME menu. Menu keys are illuminated when
active and when further menus are available. The top-level menus are:
• Ctrl (Output colour and line standard) – press F1
• Delay (Lines and samples delay) – press F2
• Rset (Board reset) – press F3
• Stat (Status) – press F4
When a sub menu has been selected, further options may be obtained by using
the shaft control to scroll through them. Once the desired option has been
located, a selection or value change can be made by either toggling the
appropriate function key or by selecting and using the shaft control to alter a
numerical value. A configuration change or value will be activated as the
shaft control is rotated or function button is toggled. The variable being
adjusted will appear in brackets. Pressing Enter will fix the new value.
The following chart shows the available REFGEN menus. The actual menus
available may vary slightly as software is updated.
Example: to adjust the samples delay setting.
From the Home menu select the Delay (Dlay) sub-menu by pressing F2. Rotate
the shaft control to display the Samples Delay sub-menu. Press F2 and note
that the second’s value now appears in square brackets. Rotating the shaft
control will now increment the sample value. Once the required value has

been reached it can be fixed by pressing the Enter button. Pressing Cal at any
time will return the value to the default of two samples.
Note: If the value change is not fixed by pressing the Enter button the value will
revert to its previous fixed value on exiting from the menu.

Crystal Vision Statesman
5 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.
Running Statesman for the first time
The Statesman PC Control System may be run from the Crystal Vision
programs folder via the Start menu or by double clicking on the Crystal
Vision.exe file in the installed program directory.
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.
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.
5.1 Statesman operation
The initial window will show an Explorer style view of the connected frames
and modules. Double clicking on a module will enable the display of the
main application menus.
