A network bridge and dedicated user interface
The NLB 60E NomadLink® Bridge & Network Controller serves
as the keystone component in all networked applications for
Lab.gruppen ‘s NomadLink-ready power ampliers. As a stand
alone unit, the NLB 60E provides facilities for monitoring amplier
parameters, detecting fault conditions, and controlling key functions
(power on/off sequencing and mute) over a proprietary NomadLink®
network comprising up to 60 ampliers.
Connecting a PC running DeviceControl software to the NLB 60E
greatly enhances the control and monitoring functions available
through NomadLink®. In this conguration, the NLB 60E operates
as a network bridge, relaying amplier status and operation
information to the host PC over a standard TCP/IP Ethernet link.
This Ethernet connection also transmits control conguration data
generated by the DeviceControl application to the NLB 60E for
dissemination to ampliers on the NomadLink® network. A secure
connection feature, with multiple levels of password protection, is
also available within DeviceControl to prevent unauthorized access
to the amplier network.
Conguring a NomadLink® network is quick and straightforward.
A large rack of ampliers can be networked in minutes simply by
clicking in Cat-5 cables and forming a daisy-chain loop beginning
and ending with the NLB 60E. Cables can be terminated with either
standard RJ45 connectors or impact-resistant Neutrik Ethercon
versions as appropriate (amplier model dependent). Phantom
power for the amplier network modules is supplied by the NLB
60E, allowing all ampliers to remain online in standby mode with
zero power consumption. To accommodate remote amplier
locations, NomadLink® allows up to 300 meters between any two
devices, and a total closed-loop subnet length of up to 700 meters.
The NLB 60E also incorporates three GPIs (General Purpose Inputs):
one voltage sensing and two contact closure. The GPIs can be
congured to respond to remote equipment such as alarm systems
and external power-up sequencers. As an alternative, internal
power-up sequencing is included in the NLB 60E.
The front-panel interface provides convenient access to amplier
status information and critical control functions. Dedicated power
on and off switches control all ampliers on the network. Other
functions and comprehensive status information are accessible by
intuitive navigation of a menu tree, with all information clearly visible
on the ultra-bright 16x2 character LED display.
