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 module from Grass Valley, a Belden Brand, is a 3 RU module for
the Densité 3 frame that offers bidirectional IP/SDI conversion. The Gateway operates with 10 GigE SMPTE 2022-6
video-over-IP, supporting 4K UHD/3G/HD/SD-SDI formats.
With the addition of intoPIX TICO mezzanine encoding and decoding option on the gateway, customers have a
convenient way to add 4K to their workflow and move 4K across the production facility. TICO mezzanine compression
is visually lossless 4:1 compression, which is lightweight and fast, perfectly suitable for live production. The IPG-3901
with purchasable TICO option provides either two (2) encodes OR two (2) decodes OR one (1) encode and one (1)
decode per card.
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.
In addition, you also have the choice to use the second ethernet port for aggregation instead of redundancy, providing
20 GigE of bidirectional bandwidth over two 10 GigE ports, increasing the capability to transport 6 in/5 out or 5 in/6 out
3G signals per IPG card. It also lets you transport more HD/SD signals in one direction taking advantage of the
bidirectional configuration of 7 BNC I/O, providing up to 9 in/2 out or 2 in/9 out. 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 Densité-3+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
rightmost 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
rightmost 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
error severity increases from left to right,
with green representing no error/disabled,
and flashing red the most severe error.
If the LED is Flashing Yellow, it means
that the card is selected for local control
using the Densité frame’s control panel.

4 Local control using the Densité frame control panel
There are two types of local control panel:
Panel type Frame models Appearance
Physical 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
[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 reverts to its normal operating mode.
To assign the local control panel to the IPG-3901:
•Physical Panel: Push the SELECT button on the IPG-3901 card edge (see Section 1.4)
•Touch-screen panel: In the home screen, touch the virtual button corresponding to this IPG-3901
The STATUS LED on the IPG-3901 flashes yellow, and the touch-screen status shows yellow for the IPG-3901.

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.
SDI Output on Error: Specify the SDI output behavior when the related gateway is on error.

5.2.2 Gateway Config panel – Gateways tab
This tab shows the current configuration of all gateways on the card, and provides controls to modify their
configuration. The contents of the tab are affected by two settings made in other panels.
TICO Status (see Section 5.5 - TICO Panel)
TICO option not
activated. This Gateways tab shows the 11 gateways associated with the 11 SDI I/O available on the rear panel. No TICO information is displayed.
TICO option
activated. Two additional TICO gateways are shown at the bottom of the table. They will be configured as ENC or DEC depending on the TICO model in use.
TICO enabled. Depending on the TICO model in use, and whether an ENC or DEC is enabled ON, as many as
8 of the 11 original gateways are reserved for TICO Link I/O, and cannot be configured in this
tab. See TICO link assignment table for detailed information.
ETH2 Operation Mode (see Section 5.3.1 - Network Config Panel - Settings tab)
OFF All gateways use ETH1 port.
Aggregation ETH port for each gateway is selectable – ETH1 or ETH2.
Redundancy Each gateway uses both ETH1 and ETH2 with identical stream addresses.
See Figure 5-3 for a view of the complete tab, showing a typical configuration with TICO active and enabled.
Actions available on the tab:
•Enable/Disable a gateway by clicking the selection checkbox in the leftmost column (“En”) of the table.
•Edit the configuration of a gateway by selecting and typing directly into the table. See description below.

SDI I/O: Each Gateway (except the TICO gateways) is
linked to a physical SDI I/O via a connector on the rear
panel. In the SDI I/O column, we have the physical SDI
I/O name on the 1st line and the gateway name on the
2nd line. The gateway name can be edited – select the
text and type a new name.
Dir.: The arrow shows the direction of signal flow
between SDI and IP through the gateway.
•There are two fixed Gateways that convert SDI to
IP Stream – SDI IN 1 and SDI IN 2.
•There are two fixed Gateways that convert IP
Stream to SDI – SDI OUT 1 and SDI OUT 2.
•The remaining seven Gateways are linked to bi-
directional SDI IOs – SDI IN/OUT 1 to 7. Each of
them can be set as either SDI-to-IP or IP-to-SDI.
Click on the arrowhead and set the direction from
the dropdown.
•TICO ENC gateways are SDI to IP.
•TICO DEC gateways are IP to SDI.
Stream Address:
•When ETH2 Operation mode is set to OFF or
Aggregation, we only have one IP stream
associated with the Gateway.
•When ETH2 Operation mode is set to
Redundancy, we have two IP streams associated
with the Gateway – Primary Stream and
Redundancy stream. The gateway will be linked to
the primary stream when it is valid. If the main
stream is in error, the gateway will fall back to the redundancy stream. The fallback may generate an error on
the SDI output.
Stream Port: Shows the port associated with the stream. Edit the port by selecting the text and typing a new value.
IGMPv3 Source: On IP-to-SDI we have an additional setting: IGMPv3 source. This is used when receiving multicast
streams. In this protocol, the card deals with a switch to subscribe to one or many streams that are coming from
different IP addresses.
•When receiving multicast streams, the “stream address” is used to talk to a “group” while the “IGMPv3 source”
indicates the exact source from which we want to receive the stream.
•When receiving unicast streams, or when not using IGMPv3, set this field to 0.0.0.0.
ETH port.: This column shows the ETH port on which we are receiving or transmitting an IP stream.
•When the ETH2 port is not used (ETH2 Operation mode = OFF) this column is hardcoded to ETH1.
•When the ETH2 port is used to send or receive more IP Streams (ETH2 Operation mode = Aggregation),
ETH port has to be set to either ETH1 or ETH2.
•When the ETH2 port is used for redundancy (ETH2 Operation mode = Redundancy), the primary stream is
always received from or sent to ETH1 and the redundant stream is always received from or sent to ETH2
Format: This column specifies the SDI format permitted on this gateway – SD, HD or 3G. To change the format, click
on the current format value, and select a new value from the drop-down (SD, HD, 3G).
•Note that TICO gateways, and gateways assigned for TICO monitoring, are forced to 3G.
