6 NLB 60E Operation Manual
Thank you for choosing the Lab.gruppen NLB 60E
NomadLink Bridge and Network Controller. We are
confident that it will provide reliable service and
exceptional operating flexibility as the keystone
component in your NomadLink amplifier control
network.
Lab.gruppen’s proprietary NomadLink network allows
easy setup and control of Lab.gruppen C Series and
FP+ power amplifiers. The patented network topol-
ogy of NomadLink allows automatic detection and
addressing of multiple amplifiers, with extensive
monitoring and control enabled on a connected PC
running Lab.gruppen’s proprietary DeviceControl
software program.
The NLB 60E serves a dual role. As a network bridge,
it provides the communication link between a host
PC running DeviceControl and the Lab.gruppen ampli-
fiers (as many as 60) connected to the NLB 60E
(referred to as a NomadlLink Subnet). Communication
between the PC and the NLB 60E is over Ethernet
using standard TCP/IP protocols; communication
between the NLB 60E and connected amplifiers is
via the robust NomadLink network.
The NLB 60E also serves as a stand-alone interface
for direct monitoring and control of many key func-
tions, including system muting and soloing, as well as
power ON/OFF utilizing the built in power sequencer.
These functions are accessible using the front-panel
displays and keypad user interface; no external PC
is required.
The NomadLink network offers a number of advan-
tages. First, phantom powering through the network
cables allows the software to detect devices that are
not currently turned on or connected to the mains.
This ensures very high reliability and redundancy,
while at the same time allowing connected amplifiers
to remain on standby with no power consumption.
Additionally, cable connections can be daisy-chained
for easier system setup. This approach reduces total
component costs, simplifies installation, and makes
daily operation more convenient. There is no need to
create a star topology using many switches as with,
for example, an Ethernet-based system. Individual
amplifier addresses do not need to be manually
entered. A daisy chain network-loop, in combination
with the automatic addressing of devices, enables
Lab.gruppen’s proprietary DeviceControl editor
software to automatically create a precise picture
of all connected devices and their relative position
in the chain.
NomadLink and DeviceControl work together to
provide a quick overview of the system layout,
allowing simple operation of a large group of
amplifiers. Installation time is kept to a minimum, and
operators have fast access to information needed
to solve problems during operation. At a glance, the
operator can simultaneously monitor all metering
data, as well as fault and warning indications, for all
amplifier channels on the subnet.
We suggest you read this manual in its entirety to
become fully acquainted with the features and func-
tions of the NLB 60E.

4.1 Unpacking
Carefully open the shipping carton and check for
any noticeable damage. Every Lab.gruppen product
is tested and inspected before leaving the factory
and should arrive in perfect condition. If found to be
damaged, notify the shipping company immediately.
Only the consignee may institute a claim with the
carrier for damage incurred during shipping. Be sure
to save the carton and packing materials for the
carrier’s inspection. Should you ever need to ship the
NLB 60E, always use the original packaging.
4.2 Mounting
The NLB 60E is one rack unit high (1U) and will fit
into a standard EIA 19” rack. The depth is 208mm
(8.2”).
The weight is approximately 2.25 kg (5 lbs.)
The NLB 60E may be mounted directly on top of other
products; there is no need for spacing in between
units, though this might enable more convenient
cabling on the rear panel.
4.3 Operating voltage
The NLB 60E contains an auto -sensing PSU accepting
line voltage between 100V and 240V AC, 50/60Hz.
Please make sure that the mains supply connection
is grounded and mounted according to local regula-
tions.
Power consumption is 35W maximum. Actual
consumption will depend upon the number of devices
supplied with 48V phantom power through the
NomadLink network.

NLB 60E Operation Manual 9
6.1 Introduction
Connecting the NLB 6 0E to Lab.gruppen amplifiers in
a NomadLink network is a simple and straightforward
procedure. All connections are made with standard
(“straight”) Ethernet-type cables equipped with RJ45
connectors. Cable grade should be Cat5 or better.
Once connected, the NomadLink network allows
direct access and monitoring of up to 60 remotely
located Lab.gruppen amplifiers per NLB 60E. Many
system parameters can be accessed via the front
panel user interface. Optionally, the NLB 60E func-
tions as a network bridge between the NomadLink
network and a PC running DeviceControl editor
software.
6.2 Connecting the NLB 60E to
the amplifiers
The NLB 60E connects to the amplifiers through the
two rear panel ports labeled NOMADLINK IN and
OUT. Using a standard (“straight”) Ethernet cable,
connect the OUT port on the NLB 60E to the IN port
on the first amplifier in the network. Next, connect
the OUT port of the first amplifier to the IN port of
the second amplifier. Continue to “daisy chain” the
amplifiers, connecting the OUT port to the IN port of
the next amplifier, until all amplifiers are connected.
Complete the network loop by connecting the OUT
port of the last amplifier to the IN port on the NLB
60E.
The OUT port of the NLB 60E must be connected
to the IN port of the first amplifier to allow the De-
viceControl software to correctly identify devices
on the network.
IMPORTANT NOTE: Within restricted cable
distances, the NomadLink network will
function as a single-ended daisy-chain
without closing the loop. (The loop is closed
by connecting the last amplifier’s OUT port back to
the NLB 60E IN port). However, it is strongly recom-
mended that the loop be completed: doing so provides
a redundant signal path and improves communication
speed on the network.

6.4 NomadLink Wiring Notes
All NomadLink ports on the NLB 60E, as well as por ts
on many NomadLink-equipped Lab.gruppen ampli-
fiers, are equipped with Neutrik EtherCon “XLR”
type connector housings. Connections may be made
with standard RJ45 connectors, or with the more
robust EtherCon connectors. The EtherCon housings
offer greater mechanical security and protection from
accidental damage.
For installations in the USA, all cables must carry the
VW-1 flame retardant rating (US National Differences
cl. 16.3).
When preparing custom Cat5 (Ethernet) cables for
the NomadLink application, all conductors in the
cable must be fully wired to the RJ45 connector. (No-
madLink uses conductor pairs that are not required
for a standard 100baseT Ethernet connection.)
6.5 NomadLink network cable
lengths
In installations where the NLB 60E is positioned at
some distance from the amplifier racks, or where
groups of amplifiers within a single subnet (up to 60
units) are located at some distance from each other,
the following general rules should be considered:
On the right side are typical examples of how
NomadLink network setups can be configured, with
maximum recommended distances shown:
• Rule 1:
The maximum cable length in between any two
devices may not exceed 300 meters / 980 feet.
• Rule 2:
In a non-closed-loop daisy-chained subnet the
total maximum cable length is 400 meters /
1300 feet.
• Rule 3:
In a closed-loop subnet the total maximum
cable length is 700 meters / 2300 feet.
6.6 GPI Connections
The NLB 60E is equipped with three General Purpose
Input (GPI) connectors on the real panel. Using these
connectors, the NLB 60 can relay commands from
external sources such as power sequencers or alarms
systems, initiating amplifier functions such as power
on/off or mute/unmute.
Two of the GPI connectors are of the contact closure
type. The third GPI connector is the voltage sensing
type (24V). All three use two-pole Phoenix connec-
tors.
More information on programming of the GPI
functions can be found in the Operation section at
9.3.5.4.

12 NLB 60E Operation Manual
7.1 Introduction and network
requirements
More detailed information on connecting
to a PC is available in the DeviceControl
Users Manual. This manual is available for
download at www.labgruppen.com under
“Support” and “Product Documentation.”
7.1.1 Introduction and network requirements
The connection between the NLB 60E and the
host PC running DeviceControl editing software is
accomplished via standard Ethernet. The commu-
nication standards are the familiar TCP/IP network
communication protocols.
The host computer must be equipped with a standard
Ethernet (LAN) network interface. The NLB 60E
supports 100baseT and full duplex only.
7.1.2 Cable connections
The NLB 60E provides two parallel Ethernet connec-
tions: one on the front panel equipped with a standard
connector, and one on the rear panel equipped with
an EtherCon connector. The rear panel connector
is ideal for permanent connection to a Local Area
Network (LAN); the front panel RJ45 allows con-
venient temporary connection for maintenance and
service.
Although two computers may be connected to the
NLB 60E simultaneously, only one is allowed access
to the subnet at a time.
7.1.3 Direct connection to PC (peer-to-peer)
A direct connection between the PC and the NLB 60E
forms a “peer-to-peer” network. In most cases, this
connection will require use of the crossed Ethernet
cable. A crossed connection is necessary because the
NLB 60E is not an auto MDI/MDX sensing unit. Note
that many newer PCs now incorporate auto MDI/
MDX sensing, a feature which may allow peer-to-
peer connection using a standard “straight” Ethernet
cable. Refer to your computer’s documentation to
determine if this is this feature is enabled.
7.1.4 Connection through Local Area Network
(LAN)
If the PC is connected to the NLB 60E through a Local
Area Network (LAN), then a standard (“straight”)
Ethernet cable should be used. A typical LAN con-
nection incorporates a hub or switch.
7.2 TCP/IP network setup
instructions
7.2.1 TCP/IP address of the NLB 60E
The NLB 60 has following factory preset default
TCP/IP values:
IP: 192.168.1.166•
Subnet mask: 255.255.255.0•
Gateway: 0.0.0.0•
DHCP usage set to OFF•
Your host PC must be manually set to the same
subnet range (192.168.1.xxx). Alternately, you may
modify the NLB 60E IP address to allow connection
to the network. See Section 9.3.5.3 for detailed
instructions.
If you have more than one NLB 60E in your TCP/IP
network, then each NLB 60E must be assigned a
unique IP address. Therefore, the last three digits (the
.166 in the default configuration) must be changed
to a unique number between 1 and 255.

NLB 60E Operation Manual 13
7.2.2 TCP/IP address of the PC
The following instructions on establishing a PC
connection to the NLB 60E may apply differently
depending on the version of the Windows Operating
System you are running. However, the IP parameters
stated will apply regardless of the Windows version
(no Mac OS X version available).
Except when using a DHCP server to automatically
obtain an IP address, you must manually set the
appropriate IP and Subnet Mask number. Using
Windows XP as an example, the following procedure
will establish the proper IP settings:
1. Go to START in lower left corner. Select: “Connect
to” and “Show all connections”
2. Select “Local Area Connection”. Select Properties
in the File menu, or by right-clicking. Highlight the
following selection: “Internet Protocol TCP/IP.” Click
on the “Properties” button.
You should see a window similar to the following:
3. Select “Use the following IP address.”
Enter a desired compatible address, such as:
19 2.16 8 .1.10 0
4. Click in “Subnet mask.” The following should
enter automatically: 255.255.255.0.
Leave “Default gateway” blank as this parameter
is not used.

7.3 DeviceControl Software
After the PC is connected to one or more NLB 60E
units in a valid Ethernet (TCP/IP) configuration,
you may launch the DeviceControl application.
DeviceControl can then either upload an amplifier
configuration from the NLB 60E subnet(s), open a
saved amplifier configuration, or create a new con-
figuration. Key features such as power ON/OFF and
amplifier channel muting will be controlled directly
from the DeviceControl windows. Please read the
DeviceControl Operation Manual for more details on
features and functionality of this software.
When DeviceControl is running and con-
nected to an NLB 60E, the front-panel
keypad commands on the NLB 60E’s will
be locked out. However GPI trigger com-
mands will not be locked out. All other control is
assumed by the DeviceControl software program.
The DeviceControl link must be removed by closing
the application to restore local control by the NLB
60E user interface. When the DeviceControl applica-
tion is closed the local control by the NLB 60E user
interface is restored.
7 connectIon to Pc FoR DevIcecontRoL
5. Click on OK. To verify that your settings are correct,
select and review the Support page.
The PC is now ready to connect to the NLB 60E when
the DeviceControl application is started.

NLB 60E Operation Manual 15
8.1 Secure Connection
NLB 60E bridge(s) in the NomadLink network-
can connect to one computer at a time running
DeviceControl software. However, if the preferred
or authorized computer is not currently connected,
any computer with DeviceControl installed may
access the NomadLink network as long as secure
connection functionality is inactive. When activated,
a secure connection restricts network access to a
DeviceControl installation with a password setting
that matches the password in the NLB 60E bridge.
A secure connection may be preferred in two
situations. First, a secure connection will prevent
unauthorized access to the NomadLink network:
only a DeviceControl application with a matching
password will be able to connect to the network.
Also, secure connections can simplify operation
and monitoring of two or more completely separate
NomadLink systems operating over the same LAN.
Several host computers can use the same network,
with each DeviceControl application accessing only
those NLB 60E bridges programmed with respective
matching passwords.
8.1.1 Enabling secure connections
Secure connection is available in DeviceControl ver-
sion 2.0 and above, and with NLB 60E firmware v
2.0 and above. Both are required. Secure connection
is disabled as default.
Enabling of a secure connection is a two-
step process. First, the secure connection
option must be enabled manually on each
NBL 60E using the front panel keypad. Then
a password must be set in DeviceControl for both
the host computer and all NLB 60E bridges with
secure connection enabled.
Once a secure connection is established in
DeviceControl, the secure connection will be retained
automatically with future software upgrades.
Enabling secure connection in the NLB 60E
Repeat the steps below for all NLB 60E bridges in
the system. DeviceControl must be offline to access
front panel functions of the NLB 60E.
Press the Select key on the NLB 60E and repeat1.
pressing until the Configuration menu appears.
Press OK.
Press Select and repeat pressing until Security2.
appears. Press OK. Press OK for Secure Conn.
After secure connection is enabled in the
NLB 60E bridges, it is important to imme-
diately enable secure connection in the
DeviceControl application. The connection
is not secure until both steps are completed.
8.1.2 Set password
From the main window, select File menu and1.
choose Settings.
Click on the Security tab.2.
Check the “Enable Secure Connection” (Figure3.

FAULT indicates that one or more devices (ampli-
fiers) on the NomadLink network have sensed a fault
condition. You may scroll through the Subnet faults to
see which unit is faulty, or connect the DeviceControl
application to access complete information on all
connected devices.
MUTE indicates that the entire subnet of detected
amplifiers is in Mute state. Locate the Mute/Unmute
display using the SELECT and OK buttons to change
the Mute state.
9.2.3 Power OFF/ON
The Power OFF/ON buttons enable the user to switch
the mains power state for ALL connected amplifiers
in the local subnet. A green LED above each button
indicates current status, either off or on. The power
sequence delay time, dictating the time between
power up activation of each consecutive amplifier
in a subnet, can be adjusted.
Please refer to section 9.3.5.5 Power Sequence
delay setting for more information on this
feature.
If an amplifier has been switched off
locally, and this was not the preconfigured
status, the NLB 60E will continue trying to
switch it back on.
9.2.4 Network LEDs and Ethernet
connection
The front-panel Ethernet connection is located at the
far right of the front-panel, adjacent to the network
status indicators.
The front-panel and rear-panel Ethernet connections
run in parallel, allowing connection of two PCs to the
NLB 60E. These two Ethernet connections operate
as a HUB.
Even though it is possible to connect two
PCs to the NLB 60E, only one is allowed
to access the subnet at a time.
The blue NOMADLINK LED illuminates when one
or more NomadLink-equipped amplifiers are con-
nected to the IN or OUT ports of the NLB 60E. A
flashing LED indicates communication activity on
the NomadLink network.
The orange ON-LINE LED indicates that a valid
Ethernet network has been detected AND that a
connected PC is running the DeviceControl applica-
tion for access and control of the NLB 60E.
The yellow ACTIVITY LED indicates active
communication between the DeviceControl applica-
tion and the NLB 60E.
