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 topol­ogy 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 Devi ceC ontro l and the L ab.gruppen ampl i­fiers (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 func­tions, 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.
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 func­tions of the NLB 60E.
Lab.gruppen Innovative Power Solutions
IMPORTANT NOTE: This manual addresses operation of the NLB 60E as installed with Firmware Version 2.0 or greater and DeviceControl Software Version
2.0 or greater. Please visit www.labgruppen.com for upgrades if you are using previous versions.
The NomadLink network offers a number of advan­tages. 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 e asier system s etup. This a pproa ch red uces 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

6.1 Introduction

Conne cting the NLB 6 0E to La b.gru ppe n amplifiers i n 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 func­tions 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 por t on the NLB 60E to the IN p ort 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 am pli fiers, connecti ng the OUT por t to th e IN por t 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 De­viceControl 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 recom­mended 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 NomadLin k ports on t he NLB 6 0 E, as well as por ts on many NomadLink-equipped Lab.gruppen ampli­fiers, 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 full y wi re d to th e RJ 4 5 co nnector. ( No­madLink uses conductor pairs that are not required for a standard 100baseT Ethernet connection.)
6.5 NomadLink network cable lengths
6.6 GPI Connections
The NLB 60E is equipped with three General Purpose In put (GPI) con necto rs on the rea l 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 connec­tors.
More information on programming of the GPI functions can be found in the Operation section at
9.3.5.4.
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.

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 commu­nication standards are the familiar TCP/IP network communication protocols.
The host computer must be equipped with a standard Ethernet (L AN) network interface. The NLB 60E supports 100baseT and full duplex only.
7.1.2 Cable connections
The NLB 60E provides two parallel Ethernet connec­tions: 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 con­venient temporary connection for maintenance and service.
Although two computers may be connected to the NLB 60E simultan eousl y, only one is allowed access to the subnet at a time.

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 con­nection 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.

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-to­peer connection using a standard “straight” Ethernet cable. Refer to your computer’s documentation to determine if this is this feature is enabled.

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 Sy stem you are running. However, the I P parameter s 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.

5. Click on OK. To verify that your settings are correct, select and review the Support page.
The PC is n ow rea dy to c onnect to the NLB 60E when the DeviceControl application is started.

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 con­figuration. 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 con­nected to an NLB 60E, the front-panel keypad commands on the NLB 60E’s will
be locked out. However GPI trigger com­mands 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 use r interface. When the Dev ice Control applic a ­tion is closed the local control by the NLB 60E user interface is restored.

8.1 Secure Connection
NLB 60E bridge(s) in the NomadLink network­can 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.
Press the Select key on the NLB 60E and repeat 1. pressing until the Configuration menu appears. Press OK. Press Select and repeat pressing until Security 2. 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 and 1. choose Settings. Click on the Security tab.2. Check the “Enable Secure Connection” (Figure 3.
8.1).

8.1.1 Enabling secure connections

Secure connection is available in DeviceControl ver­sion 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 two­step process. First, the secure connection option must be enabled manually on each
NBL 60E usi ng the front panel keypa d. T hen 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.

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 con­nected to the IN or OUT ports of the NLB 60E. A flashing LED indicates communication activity on the NomadLink network.
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.
The orange ON-LINE LED indicates that a valid Ethernet network has been detected AND that a connected PC is running the DeviceControl applica­tion for access and control of the NLB 60E.

9.3 Display navigation and features in detail

9.3.1 Introduction

The NLB 60E’s features are accessed, monitored, and adjusted using the 2x16 character display and associated keypad.
The display views are organized as a tree. The top level comprises the following “headlines.” Pressing the SELECT UP/DOWN keys moves through the headlines. Pressing the ENTER/OK button in any headline display will access a sub-display.
Please read these sections thoroughly to become familiar with the various views.

9.3.2 Homepage and Overview

On power-up, the NLB 60E will automatically inter­rogate the NomadLink network and display Subnet numbers and the total number of devices found on the Subnet.
This view is the default “Homepage” that will appear after a period of system inactivity. It is also the view that is displayed when the NLB 60E’s front UI is locked and unavailable for local operation.
The Su bnet n umber is set on the NLB 6 0 E’s Configuration page. Each subnet must be assigned a unique number.

9.3.3 Mute Subnet?

Select the “Mute Subnet?” display and press OK to gl oba lly mu te all chann els of all amplifiers c onnected to the NomadLink network.
When amplifiers are muted, the display will change to:
Press OK to Unmute all connected amplifiers.

9.3.4 NLB 60E info

The NLB 60E Info pages are all “Read only” and are provided for monitoring settings and performance.
To modify any settings, select the Configuration section.
Page 21
NLB 60E Operation Manual 21
The Subnet Number info page displays the individual identification number assigned to this particular NLB 60E as shown in the DeviceControl application.
oPeRAtIon AnD conFIGURAtIon 9
The Serial Number, MAC address and Firmware version displays are provided for convenient review, and to aid in technical support and troubleshooting. The Serial Number is also displayed by a sticker on the rear-panel of the NLB 60E.
The MAC address is the unique network identifier that is used for Ethernet communication. There is no end-user configuration of this address.
Firmware version identifies the version currently loaded in the NLB 60E. Verification of this number is recommended both before and after you perform a firmware update to ensure the process has been completed. See Appendix for more information on firmware updating.
The IP Address, Subnet Mask and Gateway pages show the TCP/IP Ethernet connection settings for the NLB 60E.
The default IP Address is 192.168.1.166. Default Subnet Mask is 255.255.255.0.
If DHCP is displayed in the top row, the IP address, Subnet Mask, and Gateway are automatically as­signed from a DHCP server connected to the Local Area Network (LAN).
The Gateway defaults to 0.0.0.0. As the NLB 60E does not support communication across routers and external network bridges in its current implementa­tion, the Gateway setting is presently redundant.
The Device number display shows devices detected on the NomadLink network. Devices are shown for th e IN por t, t he OUT p ort, an d the comb ined number of devices. The above example shows two single­ended daisy-chains connected separately to the IN and OUT ports. However, in most cases a Closed Loop is recommended.
If a Closed Loop is detected, this will be indicated in the displays as example below:
Page 22

GPI1, Low HIgh Power ON
GPI1, HIgh Low Power OFF
GPI2, Open Close Unmute
GPI2, Close open Mute
GPI3, Open Close Unmute
GPI3, Close open Mute
9 oPeRAtIon AnD conFIGURAtIon
Closed Loop detection also will be displayed in a sepa­rate window following the device info displays:
If the configuration is set to detect a loop network on the NomadLink side, and a loop is not present, this will be reported as a fault. The Fault LED on the front-panel of the NLB 60E will illuminate.
The Subnet Current display refers to the phantom power on the NomadLink network. It can show as ei ther “OK” or “Too H igh”. The NLB 6 0E supp lies t he phantom power to the subnet. If too many devices are connected, or total cable lengths are excessive (o r a combin ation of both), this may ca use excessive current draw on the phantom power supply. This condition will be reported as a fault on the front-panel LED.
The GPI displays refer to the General Purpose Input (GPI) connectors on the NLB 60E’s rear-panel.
The GPI 1 i s a Volta ge sensing input, detec ting states above and below +12V DC. GPI 2 and GPI 3 are identical contact closure inputs that detect an open or closed state.
The GPI State displays indicate the current state of the particular GPI port. GPI 1 can be either Low or High; GPI 2 and GPI 3 can be either open or closed.
The other displays provide information on the func­tion the particular GPI port is set to perform when it changes state, e.g. from Low ➞ High or from Close ➞ Open.
All GPIs can be set to perform Power On, Power Off, Mute, or Unmute; or they can be disabled.
External equipment such as fire alarm systems or power-sequencers can be connected and configured using the GPIs.
For all GPIs, note that they will perform changes only when their state is modified (e.g. going from Low to High). As long as a GPI remains in a static condition, the NLB
60E will not make any changes in amplifier status.
9.3.5 Configuration
The Configuration pages enable modification and setup of all NLB 60E features.

If No is selected, no faults will be reported even if a Closed Loop is not detected. Use ADJUST | SET up/down to toggle between Yes and No. No is the default value.
9.3.5.2 DHCP settings
DHCP enables the NLB 60E to automatically obtain an IP address and Subnet Mask from the network.
When set to On, the function is similar to what happens when the PC displays “Obtain IP address automatically”. This requires that the functions of a DHCP server be available on the network. Most standard network routers today offer this functional­it y.
When set to No (default), the NLB 60E will use the manually entered IP address (default 192.168.1.166) and Subnet Mask (default 255.255.255.0).
At times you may find it necessary to change the IP address and Subnet Mask to allow the NLB 60E to function within a Local Area Network configura­tion, or when using more than one NLB 60E in a larger system controlled by the DeviceControl editor software.
Press OK, and use the SELECT UP/DOWN arrows to move the cursor. Use the ADJUST | SET UP/DOWN arrows to change values. Press OK to verify or ESC to abort without saving the changes.
When pressing OK you will see the display read­ing:

NLB 60E has three General Purpose Input (GPI) connections which can be utilized in a variety of configurations.
Configuration of each GPI is achieved via a small set-up “Wizard”. First a primary state is selected, and then the corresponding secondary state. For example, if Mute is selected as the primary state, it will not be possible to select Power on as the secondary state. The only choices available will be Unmute or disabled.
First select the GPI port for which you desire to change settings (GPI 1, 2 or 3). Mute/Unmute will show as a default. Press OK if you wish to modify. A second display allows you to choose the action triggered by the change of state. Use the Adjust up/ down keys to select the desired action. Disabled shows as a dash (-).

A current fault indicates a problem with the NLB 60E’s phantom power supply to NomadLink.
If the Subnet contains cables that are too long or are faulty, or if too many devices are connected, this can cause excessive current draw and place the NLB 60E in protection mode. You can fix the problem by checking cables or removing devices. Note: All amplifiers on the subnet will continue to function in their current state should the NLB 60E enter protection mode.
See Appendix for cable length and number of devices on NomadLink network recom­mendations.
If the NLB 60E is configured as a Closed Loop, a fault will be reported when an open loop is detected. The information is displayed in one window as illustrated in the example above. The first shown is the device where the OUT port has been disconnected: Subnet 1, ampl ifie r 12. The second device (here t he N LB 6 0E) is the device where the IN port has been discon­nected. This feature makes it easy to determine the location of any missing Closed Loop connection.

10.4 FAQ

Following are answers to some of the most common questions asked about Lab.gruppen’s NLB 60E and the NomadLink network.
Q: Th e NL B 60E reports fewer a mplifiers than I have in the system. What’s wrong? A: Let’s say you have 20 amplifiers in a single daisy­chain and the NLB 60E reports only 12 devices. This can be due to one of the following situations:
1. The cable is disconnected (or malfunctioning) between the 12th and the 13th amplifier.
2. You have mistakenly connected the OUT port of the 11th device to the OUT port of the 12th device.
3. The total length of the cables in the network is exceeds the maximum allowed.
Q: I have connected all my amplifiers and the NLB 60E in a loop, and all cables are working. Why am I unable to detect a Closed Loop? A: Make sure that the cables in the loop are con­nected correctly all the way through, from OUT ports to IN ports, starting and ending at the NLB 60E connectors. If, for example two OUT ports are connected to each other, this will cause problems in detecting the right topology on the NomadLink network.

Update NLB 60E firmware
Follow steps 2-11 under Update NLB 60E firm­ware.
Q: Why am I unable to operate the NLB 60E’s front­panel features? A: When a PC running DeviceControl is connected to the NLB 60E, and thus directly controlling the NomadLink subnet, all commands from the front­panel and GPI connections are locked out.
Q: Why can’t I detect the NLB 60E from my PC? A: Check the Ethernet cables for faults, and check
the IP settings at both the PC and the NLB 60E.
Q: I have a “straight through” Ethernet cable that was working fine in my computer network, but it will not function in the NomadLink network. What’s the problem? A: NomadLink uses conductor pairs that are not used in many Ethernet applications. Use a cable tester to determine if the cable has one or more open conduc­tors. Also, use of premium pre-terminated Ethernet cables is recommended to avoid problems. Note that, for this same reason, all custom-terminated RJ45 connectors must be fully wired for use with the NomadLink application.
