MXB modules

The SomatXR MXB modules are front end data sourcing modules that can be used as expansion modules with the SomatXR/eDAQXR data processor. They are configurable to interface to a diverse range of transducers and sensors. Generic features for most MX modules include precision measurement capabilities using 24 bit ADCs, TEDS sensor support and multiple digital filtering options. All MXB modules have a similar back panel with a power connector, two FireWire connectors and one Ethernet connector.

MXB modules can be connected to an EXRCPU layer directly or through one or more EX23-R Ethernet switches. For more information on setting up a system with MXB modules, see Connecting MXB modules to an EXRCPU.

The data processor is designed to use Ethernet based PTPv2 protocol (IEEE1588) for time and data synchronization with MX modules and other peripherals. FireWire connections between MX modules are available and useful to simplify power distribution. When FireWire connections are used, timing and data synchronization between MX modules may or may not be based on the FireWire protocol.

CAUTION
All MXB modules in the system must have an Ethernet connection (either directly to the data processor or indirectly through an EX23-R). Connecting an MXB module to any other MXB module using FireWire without both having an Ethernet connection to the data processor can result in acquired data not being synchronized to the data processor on one or more MXB modules.

Decimal sample rates and Linear Phase FIR and Butterworth FIR digital filters that match the sample rates and digital filters in the eDAQ are available. However, the MXB modules do not phase align the Linear Phase FIR filters as the eDAQ does (i.e., the phase delay of the MXB Linear Phase FIR filters is dependent on the sample rate and digital filter characteristics). In addition, a comprehensive set of Butterworth IIR and Bessel IIR digital filters are available for use with the Decimal sample rates. The data processor also supports the traditional (Classic) HBM sample rates and IIR digital filters.

All SomatXR MXB modules can also be combined with MXB modules of the QuantumX (MXB...) and QuantumX-P (MX...-P) series and can be connected to the CX22 W data recorder and the CX27 Ethernet and EtherCAT gateway. For more information on using MXB modules in a standalone system with the catmanAP and MX Assistant software applications, refer to the MX Modules User Manual.
