Page 12: Introduction
INTRODUCTION SomatXR DAQ The SomatXR series is a rugged data acquisition system of modular design that is universally applicable for measurements of any kind. The modules in this family can be combined and intelligently interconnected specific to the measurement task. Distributed operation makes it possible to position individual modules close to the measuring points, resulting in short sense leads.
Page 13: Overview Of Modules And Transducers
The SomatXR series includes the following CX modules: CX22B-R data recorder: The CX22B-R comes with the pre-installed catman® Easy software package for test parameterization, visualization, and data analysis in the field. The acquired test data is stored on the integrated solid state drive (SSD). Information For details on the CX22B-R, refer to the separate CX22B-R operating manual.

Page 25 Notice HBK recommends mounting modules individually in environments subject to strong vibration. Individually mounted SomatXR modules are vibration- and shock-resistant in accordance with MIL-STD-202G. Top modules of stacked configurations may exceed vibration and shock specifications in environments subject to strong vibration. Make sure that the mounted modules do not exceed the vibration and shock specifications (see module data sheets).
Page 26 Instructions The casemounts have been pre-assembled. The mounting diagram is not to 1: 1 scale. The dimensions can be used as a guide for tapping the holes. 1. Insert a housing ring (B) into the slots on the side of a module. Install the two (2) case clips on opposite corners of the module, as shown in the mounting diagram.

Kit 1-CASEMOUNT3-2 contains 1-CASELINK-RUG-2 for three (3) modules. 4. First attach the mounts (F or G) to the connecting elements (CASELINK) using the M5 countersunk screws and a #2 Phillips screwdriver.
Page 28 Instructions (typical use case) Assemble the module tower completely before threadlocking the cross-head (Phillips) screws. 1. Apply a serviceable (blue) threadlocker to the four (4) M5 set screws (E) in each caselink (D). Use a 2.5 mm Allen wrench to turn the fastening screws back into the caselinks before attaching the caselinks to a module.

Page 30: Power Supply Considerations
Power supply considerations Notice Defects in the module cannot be excluded if a supply voltage > 30 V is used. If the supply voltage drops below 10 V, the modules switch off. Electromagnetic compatibility The SomatXR series and the individual modules are designed essentially for use in an industrial environment.
Page 31: Connecting A Single Module To The Host Pc
When running on a vehicle battery, we recommend installing an uninterruptible power supply unit (UPS) between the battery and the module to compensate for voltage drops during starting. For this purpose HBK offers the 1-UPX002-2, which is capable of supplying up to three MX modules with uninterrupted power.
Page 32: Connecting Multiple Modules To The Host Pc
Connecting multiple modules to the host PC Multiple connection via Ethernet with PTP or NTP synchronization Modules can be connected to the PC with standard Ethernet switches. For PTP, the Ether net switch must comply with that standard. All modules should be powered separately. Power supply B series RJ45 switch: 1-KAB273-5, EX23-R: 1-KAB2100-x...

Page 34 Multiple connection by FireWire (without CX27C-R or MX471C-R) Data is transferred, modules are synchronized, and voltage is supplied via the FireWire ports. A maximum of 12 modules can be connected in series. Notice Different voltage sources must have the same reference potential, and should be in the same voltage range.
Page 35 To connect up to 24 modules, use a hub. Hubs are devices that interconnect network chains in a star configuration. This connection method is in turn limited to 14 hops. A hop is the transition from one module to another (this means n-1 hops for n modules in a chain).

All modules are automatically synchronized when connected via the FireWire cable.
Page 41: Connecting Transducers
(EMI) and the permissible electromagnetic interference emissions (EME), has become increasingly important over the years. In the HBK Greenline shielding design concept, the measurement chain is completely enclosed in a Faraday cage by suitable routing of the cable shield. The cable shield is extensively connected with the transducer housing, and is routed via the conductive plug connector to the amplifier housing.
Page 42 In order to minimize the effects of electromagnetic interference and differences in potential, the signal ground and chassis ground (or shielding) in HBK devices are designed to be as far apart as possible. The ground connection should be the protective conductor of the mains or a separate ground potential line, as is the case for potential equalization in buildings, for example.
Page 43: Teds
4.7.1 TEDS The acronym TEDS stands for "Transducer Electronic Data Sheet", and refers to the electronic data sheet of a transducer or sensor, which is stored inseparably connected in a small electronic chip or in a relevant module. The TEDS may be located in the trans ducer housing, in the non-separable cable, or in the connector plug.
Page 44: Digitization And Signal Path
Some transducers from HBK have a special TEDS module integrated, which can transmit the TEDS data via the feedback line of a sensor (patented "zero-wire" configuration). Thermocouple and pressure sensing modules with RFID chips on the transducer connection port support TEDS technology.

7.13 CAN bus Transducer MX840B-R MX471B-R MX471C-R CAN bus CAN-FD bus Includes support for CCP/XCP-on-CAN (not in conjunction with CX23-R). To ensure trouble-free operation, the CAN bus must be terminated at both ends with suitable termination resistors. The MX471B-R, MX471C-R and MX840B-R modules have internal completion resistors between CAN H and CAN L, which can be individually activated or deactivated with the software.

8.2.2 CX27C-R via Industrial Ethernet (EtherCAT® or PROFINET) and acquisition via Ethernet Each source of an MX module is split into two signals that can be assigned different sample rates and filter parameters. For example, the first signal of an input channel may have a high sample rate (e.g. an accelerometer at 100 kS/s) and a filter disabled for analysis, while the second signal may have a lower sample rate (e.g.
