2 Installation
2.1 Installation in the Densité frame
The IRD-3811 and its associated rear connector panel must be mounted in a Densité 3-series frame (Densité 3,
Densité 3+FRx, GV Node). It is not necessary to switch off the frame’s power when installing or removing the card.
See the appropriate Densité 3 Frame manual for detailed instructions for installing cards and their associated rear
panels.
2.2 Rear Panel
The IRD-3811 has multiple inputs and outputs, and making space for all the necessary connectors at the rear of the
frame requires a double-width rear panel.
With the double-width rear panel installed, the IRD-3811 must be installed in the right-most of the two slots covered
by the panel in order to mate with the panel’s connectors.
NOTE: attempting to install the card in the wrong slot could result in damage to the edge connector of the
rear panel. BE CAREFUL
Figure 2.1 IRD-3811-3DRP Rear Panel for the IRD-3811
2.3 Connections
The rear panel connections are as follows:
•REF IN – External reference input
For external synchronization, connect a black studio reference signal to the BNC labeled REF IN.
The reference input must conform to SMPTE
170M/SMPTE 318M/ITU 624-4/BUT 470-6 for standard
definition signals and SMPTE 274M / SMPTE 296M for
high definition signals and is used to phase the HD/SD
SDI outputs to the studio.
The table shows the reference signals appropriate for the
supported input formats. In essence, the input and the
reference must have the same frame rate.
A reference mismatch will occur if there is a difference
between the input video format’s frame rate and the
reference format’s frame rate.
When a mismatch occurs, an input error will be
flagged and the card-edge Status LED will turn red to
indicate the mismatch.

3.1 Control options
The IRD-3811 can be controlled in two different ways:
•The local control panel and its push-buttons can be used to move through a menu of parameters and to adjust
parameter values (see section 3.3).
•Grass Valley’s iControl system can be used to access the card’s operating parameters from a remote computer,
using a convenient graphical user interface (GUI). (see section 3.4)
3.2 Card-Edge Status LED
The status monitor LED is located on the front card-edge of the IRD-3811, and is visible through the front access door
of the DENSITÉ frame. The chart shows how the various error conditions that can be flagged on the IRD-3811 affect
the LED status.
•If a cell in the chart is gray, the error condition cannot cause the LED to assume that status
•If more than one LED status is possible for a particular error condition, the status is configurable.
See Section 3.4.18 for details.
•The factory default status is shown by a , and forced status by an X
The LED will always show the most severe detected error status that it is configured to display, and in the chart error

3.3 Local control using the Densité frame control panel
There are two types of local control panel:
Panel type Frame models Appearance
Physical Densité-2, Densité-3, Densité-3+FR1,
Touch screen Densité 3+FR4, GV Node
The local control panel is fastened to the front of the controller card.
•The physical panel is accessed by opening the front door of the frame.
•The touch screen panel is accessed through an aperture in the frame door.
The panel consists of a display capable of displaying two lines of text, each 16 characters in length, and four
pushbuttons. The functionality of the pushbuttons is as follows:
[+] [–] Used for menu navigation and value modification
[SEL] Gives access to the next menu level. When a parameter value is shown, pushing this button once
enables modification of the value using the [+] and [–] buttons; a second push confirms the new value
[ESC] Cancels the effect of parameter value changes that have not been confirmed; pushing [ESC] causes the
parameter to revert to its former value.
Pushing [ESC] moves the user back up to the previous menu level. At the main menu, [ESC] does not
exit the menu system. To exit, re-push the [SEL] button for the card being controlled.
If no controls are operated for 30 seconds, the controller reverts to its normal standby status, and the selected card’s
STATUS reverts to its normal operating mode.
To assign the local control panel to the IRD-3811:
•Physical Panel: Push the SELECT button on the IRD-3802 card edge (see Section 1.4).
•Touch-screen panel: In the home screen, touch the virtual button corresponding to this IRD-3811.
