for PULSE and Test for I-deas From 2 to 1000+ channels in the same system LAN-XI Data Acquisition Hardware is a versatile system of modular hardware that can be used as a stand-alone, singlemodule front-end, as part of a distributed module setup, or collected in 5- or 11-module frames. The hardware works with both PULSE™ and Test for I-deas™. The individual modules have a very rugged industrial design, perfect for use in the field, and, at the same time, are plug and play modules that you can easily reconfigure in different setups. Running on AC, DC, battery or Power over Ethernet (PoE) and with interchangeable front-panel connectors, LAN-XI hardware provides an extremely flexible system: scalable from 2 to more than 1000 channels with a frequency range of 25.6, 51.2, 102.4 or 204.8 kHz and unlimited data transfer capacity. Uses and Features Uses • Real-time, multichannel sound and vibration data acquisition: from 2 to 1000+ measurement channels, all phase- and sampling-synchronous (IEEE 1588v2 Precision Time Protocol): - Stand-alone, single-module front end for small setups: up to 12 input channels or 4 input/2 output channels - Distributed, multichannel system setups with multiple single-module front ends located close to each measurement point - Multichannel systems comprising any number of front-end frames in combination with any number of singlemodule front ends • Laboratory and field measurements using the same AC, DC, battery or PoE powered system • Multipurpose conditioning of transducers: same input channel can condition all sound and vibration transducers Features • GPS sample synchronization of systems containing a Type 3660-C-100 or 3660-D-100 • Frequency range of 25.6, 51.2, 102.4 or 204.8 kHz depending on module • Low-frequency auxiliary channels (Type 3056 only) • High-speed tacho input (Type 3056 only) • CAN Bus input (Type 3058 only) • Dyn-X® technology input channels, 160 dB input range (except Type 3053) • Interchangeable front panels (BNC, LEMO or multi-pin connectors) - use your preferred cabling • Display on each module's front panel: - Simplifies system configuration and reduces the time for setting up a measurement system - Provides module status information on self-test and error conditions • Full overload detection including out-of-band overload and generator overload • Indication of faulty conditioning on each channel connector • LAN interface allows the front end to be close to the test object and reduces the number of signal cables and transducer cable length • Powered by mains, DC, battery or, for stand-alone modules, PoE (IEEE 802.3af) • Rugged and light modules cast in magnesium • Silent operation • Fully compatible with all PULSE applications • Automatic detection of hardware and transducers: - Supports IEEE 1451.4-capable TEDS transducers

System Overview LAN-XI data acquisition hardware covers a range of input/output modules that can be used stand-alone, in a distributed network or in frames holding up to 11-modules. LAN-XI hardware is extremely flexible and can be easily reconfigured, as requirements demand, into 2- to more than 1000-channel systems. Applications include: • Noise source identification using an acoustic array • Operating deflection shape • Modal analysis • Satellite qualification tests • High-frequency beamforming • Other high-channel-count measurements in sound and vibration The modules work equally well as...

4-ch. Input/HS-Tacho + 8-ch. Aux. Module LAN-XI 51.2 kHz Type 3056 This module is aimed at applications where monitoring low-frequency voltage signals along with the sound and vibration signals is required. The module offers a combination of four 51.2 kHz input channels with eight simultaneously sampled, low-frequency auxiliary channels. Unique to Type 3056 is the support of high-speed tacho signals on input channels 1 – 4, which lets you record the signals needed to perform angle domain analysis using PULSE Reflex™ Angle Domain Analysis Type 8740. Type 3056 features four DC outputs that...

1-ch. Input + 1-ch. Output Module LAN-XI 204.8 kHz Type 3161 Specifically aimed at high-frequency applications such as transducer calibration and underwater defence applications, Type 3161 offers a combination of one input channel and one generator output channel. Both input and output channels have a frequency range of DC to 204.8 kHz. The combination of input connectors - Direct/CCLD, 200 V and Charge - on the front panel allows connection to virtually any microphone and accelerometer, including direct connection to Hydrophone Types 8103, 8104, 8105 and 8106.

System Configuration The ability to use any module as stand-alone, in a frame or in a distributed system means that you can place your modules close to the measurement object, and the Precision Time Protocol (PTP) makes it possible to synchronize the clocks in the system components with sub-microsecond accuracy. With PoE, all you need between the modules and the PC are shielded CAT6 LAN cables and a PoE switch. This minimizes the number of cables required and results in lower cost, less downtime, easier maintenance, greater flexibility and greater installation speed. Fig. 1 Using LAN-XI,...

Building a Configuration Configurations of one or more LAN-XI modules and frames are easily managed using a front-end browser via the PULSE Front-end Setup program. You can select modules and frames, access the modules’ home pages, change IP addresses, flash the modules’ LEDs and update firmware. IP Addresses Each module has its own built-in network interface. This can be configured to use dynamic or static IP addressing, via the module’s display or its home page: • If the modules are set up to use dynamic IP addresses (default), the modules automatically receive their IP addresses from a...

GPS Sample Synchronization GPS sample synchronization is available with LAN-XI Front-end Frame Types 3660-C-100 and 3660-D-100. Traditional data acquisition configuration requires a cabled synchronization mechanism to acquire samplesynchronous data on all front ends and modules, a prerequisite of many sound and vibration applications needing cross-spectral analysis between channels. Applications such as automotive pass-by, fly-by or structural tests on large or moving constructions such as buildings, bridges or wind turbines, make it very cumbersome, and often impossible, to deploy a...
