eight channels in the same direction).
Notes
Features
The NXL-IP55 IP Live Production Unit is an IP
transmission device that allows upstream and
downstream transmission of HD video signals, audio
signals, and various control signals with low latency of
less than one field (excluding network delays). Using the
unit allows you to configure a live production system over
a network.
Network synchronization
Devices can be synchronized via a network. Low-latency
video transmission is made possible during live
production by eliminating the need for synchronization
via a frame synchronizer.
Various transmission signals
Up to four video channels are available for transmission
with up to three in the same direction. Ten audio channels
(five pairs) are available for transmission with eight in the
same direction. Eight GPIO channels, six tally channels,
and one channel for a synchronization signal are also
available.
Note
The content of this document applies to firmware version
V1.10.
NXL-IP55 units with different firmware version cannot
be connected together. You can check the firmware
version in [Device Information] on the [Status] page in
the Web menu.
If using an NXL-IP55 unit with a different firmware
version, contact your store or point of purchase.
• HD-SDI embedded audio can be transmitted on Ch1 to
Ch2 or Ch1 to Ch4. The audio will not be transmitted
on Ch5 and above.
Metadata attached to HD-SDI signals cannot be
transmitted.
• When transferring Dual Link SDI, audio signals can be
embedded in Link-A only.
Tally signals
Three channels each are available for R tally signals and
G tally signals.
However, the transmission direction for all channels is the
same.
GPIO
Eight channels are available.
The transmission direction can be switched by using four
channels as one group.
Supported Networks
Use this unit in a network that meets the following
specifications. Check whether the network you want to
use fulfills these requirements by performing a network
test in the web menu before use.

3. Network settings
The network settings are configured on the [Network]
page.
Settings must be configured for the MAIN connector
network, which transmits the main line signal, and the
CONTROL connector network, which connects to the
computer used to setup this unit.
MAIN connector settings
These are configured under [Main Port Configuration] on
the [Network] page.
Although it is one connector, it has two IP addresses –
Main 1 and Main 2. When you configure the IP address
for Main 1, a sequential IP address is configured for Main
2 automatically. Make sure that the IP addresses do not
overlap with other devices.
• [Host IP Address (1/2)]: Enter the IP address for Main
1.
• [Host IP Address (2/2)]: This is configured
automatically when you enter an address for [Host IP
Address (1/2)]. This cannot be modified.
• [Subnet Mask]: This setting is the same for Main 1 and
Main 2.
• [Destination IP Address (1/2)]: Enter the Main 1 IP
address of the other connected NXL-IP55 unit (i.e., the
connection destination).
• [Destination IP Address (2/2)]: This is configured
automatically when you enter an address for
[Destination IP Address (1/2)]. This cannot be
modified.
• [Speed]: Displays the connection speed.
• [Stream Mode]: Set to “Multicast” if using the PC
application software (optional), or set to “Unicast”
otherwise.
Note
When configuring settings, be sure to click the [Apply]
button after configuring settings in each web menu page.
If you switch to a different page or close the web browser
without clicking the [Apply] button, the settings will not
be applied.
The factory settings for this unit’s CONTROL connector
are as follows.
IP address: 192.168.0.3
Note
In Multicast mode, multicast packets are sent from the
switch to all ports, which may affect communication on
other ports. In order to avoid this, use the IGMP
snooping function and IGMP query function of the
switch to monitor traffic, or take other measures such as
segmenting the network connected to the MAIN
connector and the network with the CONTROL
connector using VLANs.
Settings
11
• [Multicast Address]: If “Multicast” is configured in
[Stream Mode], set the IP addresses. Six addresses are
required. Setting one address automatically sets the
remaining five addresses in sequence. Set
corresponding addresses on the connected devices. If
“Unicast” is configured in [Stream Mode], no entry is
required.
• [Register IP Address]: If a computer running the PC
application software (optional) is connected, enter the
IP address of the computer. Set [Stream Mode] to
“Multicast” to configure this parameter. The required
address is the IP address of the computer connected to
the same network segment as the MAIN connector of
the unit. IP addresses for up to eight computers can be
configured.
CONTROL connector settings
These are configured under [Control Port Configuration]
on the [Network] page.
• [DHCP]: Select whether to use DHCP. When using
DHCP, the IP address allocated to the unit can be
monitored using character information superimposed
on the monitor output.
• [IP Address], [Subnet Mask], [Default Gateway]:
Configure these if [DHCP] is disabled.
[2Transmit 2Receive] is specified, specify [2Transmit
2Receive] again for the partner device.
If “1080/59.94P (Dual Link)” or “1080/50P (Dual
Link)” is selected in [Video Format], [Structure] is
fixed to “2Transmit 2Receive” and Dual Link 1
operates in bidirectional transfer mode. Connect the
Link-A input to HD SDI IN connector 1, and the LinkB input to HD SDI IN connector 2. The HD SDI IN 3
connector is disabled. Connectors HD SDI OUT 1 and
2 are grouped, as are connectors HD SDI OUT 3 and 4.
Link-A is output from connectors HD SDI OUT 1 and
3, and Link-B is output from connectors HD SDI OUT
2 and 4.
6. Synchronization settings
Configure synchronization between transmission
devices.
Selection of whether a device is the Leader or Follower in
regards to the synchronization signal is performed under
[Network GenLock] on the [Structure] page.
Select [Leader] for the transmitting device, and
[Follower] for the subordinate device. Transmission is
not possible between two Leader devices or two Follower
devices.
Note
When specifying IP addresses for the MAIN connector
and the CONTROL connector, do not use multicast
addresses, broadcast addresses, or other special reserved
addresses.
4. Format settings
Select the image format for transfers under [Video
Format] in the [Structure] page.
5. Video transmission settings
The direction of the video’s main line signal and the
number of transceiver channels are configured under
[Transmission Settings] on the [Structure] page.
• [Main Video Direction]: Select [Transmitter] for the
camera transmitting main line signals, and [Receiver]
for the video router receiving the signals.
On the Receiver side, the phases of the input SDI
signals and the SDI signals sent from the Transmitter
will match. On the Transmitter side, the phases of the
input SDI signals and the SDI signals sent from the
Receiver will not match (when [Frame Synchronizer] is
[OFF]).
Selecting the [Transmitter] and [Receiver] establishes a
pair. Communication will not be possible if both sides
are set identically.
• [Structure]: Configure the number of transmitter/
receiver channels. The number of channels for the
Transmitter and the Receiver should be inverted.
For example, in a 3-camera system with one return
channel, specify [3Transmit 1Receive] for the cameras
and [1Transmit 3Receive] for the video router.
Alternatively, if [3Transmit 1Receive] is specified,
specify [1Transmit 3Receive] for the partner device. If
Next, select the synchronization signal to be input under
[Reference in] on the [I/O] page.
• [Source]: Select either the input signal from the REF IN
connector or from HD SDI IN connector 1 to be the
synchronization signal.
• [Format]: When [Reference in] is selected for [Source],
select [HD] (HD 3-value sync) or [SD] (SD sync).
• [V Phase]: Enter this unit’s vertical phase for the input
synchronization signal.
The input signal must be in phase with this unit.
However, an unsynchronized signal can be input if there
is only one channel. In such cases, use the frame
synchronizer. For details, see “Settings when using a
frame synchronizer” on page 18.
The synchronization signal to be output from the REF
OUT connector is configured under [Reference out] on
the [I/O] page.
• [Format]: Select [HD] (HD 3-value sync), [SD (BB)],
or [SD (SYNC)] (SD sync) as the synchronization
signal to be output.
• [V Phase]: Enter this unit’s vertical phase for the output
synchronization signal.
