Electrostatic Discharge (ESD) Protection
Electrostatic discharge occurs when electronic components are improperly handled and can result in
intermittent failure or complete damage adversely affecting an electrical circuit. When you remove and
replace any card from a frame always follow ESD-prevention procedures:
•Ensure that the frame is electrically connected to earth ground through the power cord or any other means if
available.
•Wear an ESD wrist strap ensuring that it makes good skin contact. Connect the grounding clip to an unpainted
surface of the chassis frame to safely ground unwanted ESD voltages. If no wrist strap is available, ground
yourself by touching the unpainted metal part of the chassis.
•For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and
10 megohms.
•When temporarily storing a card make sure it is placed in an ESD bag.
•Cards in an earth grounded metal frame or casing do not require any special ESD protection.

1 IPG-3901 High Density SDI/IP Gateway for Densité 3 Platform
1.1 Introduction
The Densité IP Gateway (IPG-3901) plug-and-play modules seamlessly bridge hybrid SDI/IP production
environments. As broadcasters migrate to IP-based transport, these space-saving, low-power cards are easily added
to existing Densité signal processing platforms, converting real-time, uncompressed, baseband video using SMPTE
2022-6 protocol for distribution over 10 GigE networks, and vice versa.
The gateways support any mix of 3G/HD/SD-SDI production workflows over IP networks. With bidirectional I/O in
combinations of 5 in/6 out or 6 in/5 out, the cards offer full redundancy in either unicast or multicast workflows to
ensure uninterrupted service.
Based on the proven Densité modular framework of over 100 functional cards, the flexible, space-efficient IPG-3901
cards accommodate a gradual adoption of IP production elements into broadcasting workflows, while protecting
operational methods and investment in installed equipment. With flexibility to configure up to 6 IPG-3901 modules per
Densité 3 frame and with each IPG-3901 module carrying 11 HD or 6 3G gateways, the Densité 3 platform scales to a
density of 66 HD or 36 3G gateways in a 3 RU frame. In the new Densité 3+ FR4 frame, up to12 IPG-3901 modules
can be installed giving a density of 132 HD or 72 3G gateways in a 4 RU frame. This means space- and cost-efficient
scaling – today and tomorrow.
The Densité IP Gateway can be controlled by the advanced GV Convergent SDN platform, offering unified control
across COTS IP switches and SDI routing/processing infrastructures, as well as by the proven iControl systems.

2 Installation
2.1 Installation of Rear Connector Panels
Grass Valley Densité-series cards are each associated with a rear connector panel, which must be installed in the
Densité frame before the card can be inserted.
The IPG-3901 card is designed to fit into Grass Valley’s Densité-3 and Densité 3+ frames. Two different rear
connector panels are available:
•IPG-3901-3TRP Triple-slot-width panel for Densité-3
•IPG-3901-3+DRP Double-slot-width panel for Densité-3+FR1 and FR4
See section 2.3 for details of the signal connections available on these panels.
All cards and rear panels can be installed with the frame power on. The card has connectors that plug into a mid-
frame mother board for distribution of power and for connection to the controller card, and a second connector that
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 remove an existing card from the slot, tilt the swivel handle on the front of the card to lever the
connectors apart, then use the handle to pull the card straight out of the slot.
To install the connector panel:
1. If a card is installed in the slot whose rear panel is being changed, remove it as described above.
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 (Densité 3 or Densité 3+ FR4) or side (Densité 3+ FR1) of the panel.
3. Position the new panel and secure it in place with the captive screw(s) at the bottom or side.
2.2 IPG-3901 Card Installation
Once a matching rear connector panel is in place, install the IPG-3901 card as follows:
1. Open the front panel of the frame.
2. Slide the IPG-3901 card into the slot and push gently on the handle to seat the connectors.
•When using a triple-slot-width rear panel in a Densité-3 frame, the card should be inserted into the right-
most of the three slots.
•When using a double-slot-width rear panel in a Densité-3+ FR1 frame, the card should be inserted into the
lower of the two slots.
•When using a double-slot-width rear panel in a Densité-3+ FR4 frame, the card should be inserted into the
right-most of the two slots.
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.

3 User Interface
3.1 Control options
The IPG-3901 can be controlled in two different ways:
•The local control panel and its push-buttons can be used to move through a menu of status reports (see section
4).
•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 5).
3.2 Card-Edge Status LED
The status monitor LED is located on the front card-edge of the IPG-3901, and is visible through the front access door
of the DENSITÉ 3 frame. This multi-color LED indicates the status of the IPG-3901 by color, and by flashing/steady
illumination.
The chart shows how the various error conditions that can be flagged on the IPG-3901 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 Alarm Config Panel for details.
•The factory default status, if available, 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

4 Local control using the Densité 3 frame control panel
4.1 Overview
Push the SELECT button on the IPG-3901 card edge
(see section 1.4) to assign the local control panel to
operate the IPG-3901. Use the control panel buttons to
navigate through the menu, as described below.
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 local control panel is fastened to the front of the
CPU-ETH2 controller card, and when installed is
located in the front center of the frame, positioned in front of the power supplies. The panel consists of a display unit
capable of displaying two lines of text, each 16 characters in length, and five pushbuttons.
The panel is assigned to operate any card in the frame by pushing the SELECT button on the front edge of that card.
•Pushing the CONTROLLER button on the control panel selects the Controller card itself.
•The STATUS LED on the selected card 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.
If no controls are operated for 30 seconds, the controller reverts to its normal standby status, and the selected card’s
STATUS LED reverts to its normal operating mode.
4.2 Menu for local control
The IPG-3901 has operating parameters that may be adjusted locally at the controller card interface.
•Press the SELECT button on the IPG-3901 front card edge to assign the Densité frame’s local control panel
to the IPG-3901
•Use the keys on the local control panel to step through the displayed menu to configure and adjust the IPG-
3901

System-wide Scan Rate: Use the pulldown to
select the scan rate for the system.
•Any input not matching this rate will be
considered invalid.
Receiver FIFO Level (Packets):
This setting determines the number of packets
retained in the input buffer (FIFO).
Generally, IP data streams passing through a network with multiple switches will suffer from “packet jitter”, which must
be processed out in a buffer before conversion to a continuous SDI video signal. If the necessary packets have not
been received before conversion, dropouts will appear in the video. The larger the buffer, the more likely all the
necessary packets will have been received, but the buffer adds latency to the processing, which is not desirable.
The object is to achieve error-free video with the lowest buffer size.
Use the slider, or type directly into the data box, to set the buffer size.

This page shows the current configuration of all 11
gateways on the card, and provides controls to
modify the configuration.
•Enable/Disable a gateway by clicking the
selection checkbox in the leftmost column (“En”)
of the table.
•Select a gateway by clicking anywhere in its
row in the table.
•Edit the configuration of the selected gateway
using the controls at the bottom.
The table in the panel shows the following:
•En. – checkbox showing enable status
•SDI I/O – 1st line: Name of gateway (fixed)
2nd line: Gateway name
(set in Names tab)
•Dir – the arrow shows the direction of signal
flow between SDI and IP through the
gateway.
•Format: The (non-specific) signal format:
(SD, HD, 3G)
The following two entries show two rows each:
Top row – primary stream information
Bottom row – redundant stream information
•Stream Address – The IP address (source or
destination, depending on the direction of
signal flow) of the stream (unicast or
multicast). In this table, the port is shown
appended to the address (IP:port)
•IGMPv3 Source – Useful only when IGMP is
used. In this protocol, the card deals with a switch to subscribe to one or many streams coming from different IP
addresses. When IGMP is used, the field “stream address” is used to talk to a “group” while the “stream
source” indicates the exact source from which we want to receive the stream.
Note that only one gateway at a time can be fed by a “socket” (stream IP address + port).
