HDA-395N-3SRP-R 3 BNC 1 2 x 3 2
HDA-395N-3SRP-D 3 DIN 1 2 x 5
.
All cards and rear panels can be installed with the frame power on. The card has connectors which plug into a mid-
frame mother board for distribution of power and for connection to the controller card, and a second connector which
plugs directly into the rear connector panel for input and output.
The rear connector panel must be installed with the card out of the frame.
To install the connector panel:
1. If a card is installed in the slot whose rear panel is being changed, remove it by tilting up the swivel handle on
the front of the card to lever the connectors apart, then using the handle to pull the card straight out of the slot.
2. Remove the existing panel (either blank or belonging to an existing card that is being changed) by releasing the
captive screw(s) at the bottom.
3. Position the new panel and secure it in place with the captive screw(s) at the bottom.
2.2 Installing the HDA Card
Once a matching rear connector panel has been installed, install the HDA card as follows:

GUIDE TO INSTALLATION AND OPERATION
HDA-1941/51 & HDA-3941/51 | 5
1. Open the front door of the frame.
2. Slide the HDA card into the slot and push gently on the swivel handle to seat the connectors.
If the card is used with a double-width rear panel, it should be inserted into the right-hand slot. Inserting the card
into the wrong slot will not damage the card, and will be flagged by the on-card status LED flashing red to
indicate that there is no connection to the rear panel.
3. Close the front door of the frame.

3G-HD-SD IN – serial digital video inputs
Connect a serial digital video signal, conforming to the SMPTE 424M for 3 Gbps input signals, the SMPTE 292M
standard for HD input signals or SMPTE 259M standard for SD input signals, to the BNC labeled 3G-HD-SD IN. DVB-
ASI is also supported. The HDA will automatically switch to the detected video line format.
3G-HDSD OUT – serial digital video outputs
The HDA provides multiple 3G/HD/SD SDI video outputs, labeled 3G-HD-SD OUT 1,2, etc. The SDI video signal
conforms to the SMPTE 424M, SMPTE 292M or SMPTE 259M-C standard. All outputs are DVB-ASI compatible.
2.4 Bypass Relay
Rear panels with an integrated bypass relay or relays are identified by a –R designation. The relays activate
automatically if the card loses power, or is removed from the frame.
When activated, the relays connect the 3G-HD-SD SDI input directly to 3G-HD-SD SDI output 1, ensuring that the
signal is available downstream.
When the card is re-activated, the relay disengages.

3 Operation
3.1 Control Options
All of the cards installed in a Densité frame are connected to the frame’s controller card, which handles all interaction
between the cards and the outside world. There are no operating controls located on the cards themselves. The
controller supports remote operation via its Ethernet ports, and local operation using its integrated control panel.
The HDA 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 HDA, and is visible through the front access door of
the DENSITÉ 3 frame. This multi-color LED indicates the status of the HDA by color, and by flashing/steady
illumination.
The chart shows how the various error conditions that can be flagged on the HDA affect the LED status.
•If a cell 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 3.4.4 for details.
•The factory default status is shown by a 
The LED will always show the most severe detected error status that it is configured to display, and in the chart error
severity increases from left to right, with green representing no error/disabled, and flashing red the most severe error.

3.3 Local control using the Densité frame control panel
Push the SELECT button on the HDA card edge (see Section 1.4) to assign the local control panel to operate the
HDA. Use the control panel buttons to navigate through the menu, as described below.
•The complete menu structure is shown in Annex 1 to this document, beginning on page 20.
Two versions of the local control panel exist:
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.
Assign the panel to operate the HDA by pushing the SELECT button on the front edge of the HDA card.
•The STATUS LED on the HDA flashes yellow.
The local control panel displays a menu that can be navigated using the four pushbuttons located beside the display.
The functionality of the pushbuttons is as follows:
[+] [–] Used for menu navigation and value modification
[SELECT] 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 [SELECT] button for the card being controlled.
Notes:
1. If you do not touch any buttons on the local control panel, the controller will revert to its normal
