Page 5: Ref-1801 Hd/Sd Frame Reference Module
1 REF-1801 HD/SD Frame Reference Module 1.1 Introduction The REF-1801 provides distribution of a universal reference signal (URS) to all the cards within the same Densité frame, while generating a selectable reference signal for external use. The unique URS concept provides significant advantages as it digitally generates reference signals and simplifies inter-format processing by using a unique reference signal for all video and audio frame rates. -
Page 6: Card Front Edge Layout
Application 1: Referencing converters and frame sync modules In this application, the REF-1801 accepts a reference input and generates a URS4D signal that is distributed to all Densité slots within the same frame. This is the most basic application for our reference card. - Page 7 Feeding 3 party equipment that requires REF (e.g.: tri-level sync) In this application, the REF-1801 card is used to generate a reference signal to feed 3rd party equipment. This might be very useful, especially when the 3 party equipment needs a tri-level sync reference signal.

2.2 Installation in the Densité frame The REF-1801 must be mounted in a DENSITÉ-2 frame. The installation includes both the REF-1801 module, and the rear panel module. It is not necessary to switch off the frame’s power when installing or removing the card. -

3.2 Local control using the Densité frame control panel Push the SELECT button on the REF-1801 card edge (see Section 1.4) to assign the local control panel to operate the REF-1801. Use the control panel buttons to navigate through the menu, as described below. -
Page 10: Status Led
3.2.1 Status LED The status monitor LED is located on the front card-edge of the REF-1801, and is visible through the front access door of the DENSITÉ frame. This multi-color LED indicates module status by color, and by flashing/steady illumination, according to the chart. The chart also indicates fault reporting for this card on the DENSITÉ... -
Page 11: Menu For Local Control
The REF-1801 has operating parameters which may be adjusted locally at the controller card interface. After pressing the SELECT button on the REF-1801 module, use the keys on the local control panel (described above) to step through the displayed menu and adjust the parameters. The menu is shown below. -

The basic window structure for the REF-1801 is shown in figure 3.1. The window identification line at the top gives the card type (REF-1801), and the slot number in which the card is installed in the Densité frame. On the left is a Status icon for the card. - Page 13 3. The contents of the selected tab, with operating controls and status monitors as required. 4. The Load Factory button. Clicking this button will reset all REF-1801 parameters to factory-default values, overriding settings made in the control panels. REF-1801 | 9...

Normal – In normal mode, the URS signal generated contains only the synchronization signals that match the reference format used by the REF-1801. That is, if input is NTSC, only 29.97Hz synchronization signals are sent. Free Run – If the freerun mode is selected, all URS synchronization signals are generated, even the frame-rate- mismatched ones. - Page 16 • • Word Clock 48 kHz Vertical (lines) – the slider selects the vertical offset between the reference input to the REF-1801 and the output being configured. • The nominal range is +/- one frame, and is indicated (in lines) at the ends of the slider •...

Overall Alarm associated with this card. The Overall Alarm is shown in the upper left corner of the iControl panel, and also appears at the bottom of the Status/Name column. Figure 3.6 Alarms tab REF-1801 | 13... - Page 18 The alarm exists but has no effect (used for text and composite alarms) Shortcut: if you click in one of the columns beside REF-1801 in the Status/Name column (where there is no pulldown shown), you will open an “invisible” pulldown that lets you assign a level to all alarms in that column simultaneously.
