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

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”).
InstALLAtIon 4
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 6 0E cont ain s an auto -s ens ing P SU ac cepting line voltage between 100V and 240V AC, 50/60Hz.
Please make sure that the mains supply connection is grounded and mounted according to local regula­tions.
Power consumption is 35W maximum. Actual consumption will depend upon the number of devices supplied with 48V phantom power through the NomadLink network.

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.
