What can you measure with Ethernet DAQ systems
A Dewesoft Ethernet data acquisition system can be configured for a wide range of signal types and sensors. Typical measurements include voltage, current, IEPE sensors, accelerometers, strain gauges, thermocouples, RTDs, digital signals, encoder inputs, CAN bus data, and more. Ethernet-based setups are especially useful when measurements must be distributed across multiple locations or when high channel counts require flexible system expansion.
Typical applications
Ethernet data acquisition systems are widely used in automotive testing, structural testing, power analysis, machine monitoring, industrial measurements, durability testing, aerospace testing, and research. They are especially valuable in applications that require synchronized data acquisition across longer distances, multiple devices, or larger test setups.
Included for free: DewesoftX award-winning DAQ software
Dewesoft EtherCAT DAQ systems are powered by our award-winning DewesoftX software, which enables real time data visualization, recording, post processing, and reporting in a single environment. Users can configure channels quickly, view live data, combine multiple data sources, and export results for further analysis.
DewesoftX is included with every Dewesoft DAQ system and updates are free for life. Because the same software runs the entire range, adding slices to an EtherCAT chain or moving to a larger system means no new licence and no retraining — the setup you build today still works when the channel count grows.
DewesoftX also includes a module for ENI file export, so Dewesoft EtherCAT systems can easily be integrated into 3rd-party EtherCAT masters such as NI LabVIEW, MTS FlexTest, Beckhoff, and others.
Ethernet data recorders and loggers
Not every test needs a PC in the loop. When a measurement has to run unattended — on a remote structure, inside a vehicle, on a machine that runs for weeks — what you need is an Ethernet data recorder: an instrument that acquires, processes and stores data on its own, and that you reach over the network when you want the results.
OBSIDIAN is built for exactly that. It is a data logger and an embedded DAQ system in one fanless, ARM-based Linux unit, connected over Gigabit Ethernet (RJ45) and available with WLAN. Data is written to 4 GB of internal eMMC storage and expanded with an SD card up to 2 TB or USB-C external storage, so a recording session is limited by the card you fit rather than by the link to a host PC. Dual redundant 9–48 V DC power and typical consumption of 5.8 to 7.3 W make it practical to run from a vehicle supply or a battery installation, and rugged variants extend the operating range to -40 °C with IP67 ingress protection.
Because it is a networked instrument rather than a closed logger, the data does not have to be collected by hand. OBSIDIAN streams over OPC UA and XCP over Ethernet, is openDAQ compliant, and synchronises with the rest of your system over PTP IEEE 1588v2, IRIG-B or GPS PPS — so a recorder left in the field stays time-aligned with a lab system at the other end of the network. Embedded processing runs on board as well: math, filtering, FFT, statistics, fatigue analysis, power calculations and alarms. What you retrieve is results, not raw gigabytes.
For continuous remote monitoring rather than test campaigns, NEMOSENSE is a low-noise vibration data logger with an Ethernet RJ45 interface, passive PoE or 802.3af power, and an optional 4G/LTE link. At the high-rate end, SIRIUS XR records locally through the XR-SBOX, which carries a non-removable 1 TB NVMe drive behind a 10G SFP uplink.

How Dewesoft Ethernet DAQ systems connect, power and synchronise
One cable for data, power and synchronisation
On SIRIUS X and IOLITE X, a single RJ45 cable carries all three. Each unit takes PoE++ power at 48–57 V DC with up to 90 W available down the chain, so a measurement point needs no local power supply — useful when the sensor sits at the top of a tower or inside a sealed enclosure. Devices daisy-chain directly to one another with up to 100 m of cable between them, so a distributed test setup is built from the instruments themselves rather than from a rack of separate power and sync wiring.
Synchronisation to 100 nanoseconds
Every Dewesoft Ethernet instrument synchronises over PTP — IEEE 1588v2 — and SIRIUS X and IOLITE X hold 100 ns accuracy across the chain. That is what makes Ethernet usable for measurement rather than just data transfer: channels recorded at one end of a building stay phase-correct against channels recorded at the other. Where a test spans more than one system, SIRIUS XR adds IRIG-B-DC inputs and a 10 MHz clock reference, and OBSIDIAN supports IRIG-B and GPS PPS alongside PTP over UDP and PTP IEEE 802.3 (Layer 2).
Bandwidth, from 1 GbE to 10G fibre
SIRIUS X, SIRIUS XHS, SIRIUS XHS-PWR, IOLITE X and OBSIDIAN connect at 1 GbE. SIRIUS XR uplinks over two 10G SFP ports in copper or fibre — fibre being the practical choice over long runs, or in electrically harsh environments where copper picks up interference. The XR-SBOX adds a 2.5 GbE port of its own. Bandwidth is matched to channel count and sample rate instead of being fixed by the bus.
Why a standard network switch is not enough
An office switch will pass the data but not the timing: ordinary switching introduces variable delay, and that jitter lands directly on your synchronisation. DS-LAN switches are PTPv2-aware (IEEE 1588-2008, peer-to-peer and end-to-end), so timing survives the hop. The DS-18xLAN carries twelve 2.5 GbE front ports with 10 GbE SFP uplinks, supplies Power over Ethernet to up to twelve devices, and mounts in the standard SIRIUS modular form factor. Connector choice is RJ45 or Lemo, depending on whether cost or ruggedness matters more.
Getting the data into your own software
Not every setup ends in DewesoftX. SIRIUS XHS, SIRIUS XHS-PWR and OBSIDIAN publish data over OPC UA and XCP over Ethernet, so a DAQ system drops into an existing SCADA system, test-bench controller or real-time platform without a custom driver. OBSIDIAN is openDAQ compliant as well, giving you an open-source SDK path for reading data straight into your own application.
Frequently asked questions about Ethernet DAQ systems
An Ethernet DAQ (data acquisition) system is a measurement instrument that connects to your network over standard Ethernet rather than to a single PC. Sensor signals — voltage, vibration, strain, temperature, sound, CA — are digitised at the device and streamed over the network, so channels can be spread across a site and still recorded as one synchronised measurement.
Dewesoft Ethernet systems synchronise using PTP (IEEE 1588v2). SIRIUS X and IOLITE X hold 100 ns accuracy across a daisy chain, so channels recorded on different devices stay phase-correct. Where a test spans several systems, SIRIUS XR adds IRIG-B and a 10 MHz clock reference, and OBSIDIAN supports IRIG-B and GPS PPS.
Up to 100 metres of cable between devices, and because SIRIUS X and IOLITE X daisy-chain, each hop adds another 100 m. That covers most buildings, test cells and structures without extra hardware. For longer distances or electrically noisy environments, SIRIUS XR uplinks over fibre using its 10G SFP ports.
Yes. SIRIUS X and IOLITE X accept PoE++ at 48–57 V DC, with up to 90 W available down a chain, so a single RJ45 cable carries data, power and synchronisation. A measurement point at the top of a tower or inside a sealed enclosure needs no local power supply.
For synchronised measurement, yes. An ordinary switch forwards the data but adds variable delay, and that jitter degrades timing. DS-LAN switches are PTPv2-aware (IEEE 1588-2008), so synchronisation survives the hop. The DS-18xLAN also supplies Power over Ethernet to as many as twelve devices, with RJ45 or Lemo connectors.
Choose Ethernet when devices are spread across a site, when you want to use standard network infrastructure, or when the system streams to a PC or server. Choose EtherCAT when you need deterministic, hard real-time behaviour and tight cycle times — typically test-bench and HIL applications where the DAQ system feeds a controller.
Ethernet suits distributed measurement: many units across a site, long cable runs, power over the same cable, and recording that continues without an attached PC. USB suits a single portable instrument sitting beside a laptop, with no network configuration at all. Channel count and distance usually decide it, rather than speed.
Yes. OBSIDIAN is a standalone data logger and embedded DAQ system in one: an ARM-based, fanless unit that records to internal eMMC storage or an SD card of up to 2 TB, runs math, filtering and alarms on board, and is reached over Gigabit Ethernet when you want the results.
Also our SIRIUS X and IOLITE X units can run completely autonomously with the same integrated ARM-based CPU and DewesoftRT software.
Yes. All our openDAQ supported devices (OBSIDIAN, SIRIUS X, SIRIUS XHS and IOLITE X) can sream data to external applictions, programming languages, SCANA and Cloud systems using industry standard data protocols such as OPC UA, MQTT, XCP, and others.
