Anyone can review and analyze stored data files using the included DewesoftX software, which is an award-winning tool for data acquisition and signal processing.
Use OBSIDIAN® with DewesoftX data acquisition software
Rather than exclusively running embedded DewesoftRT software, the OBSIDIAN® devices can be used like any other Dewesoft DAQ device connected to a PC running DewesoftX data acquisition and signal processing software. There are two possible ways to do this:
- EtherCAT®: In this so-called external master mode, OBSIDIAN® devices are connected to the PC via Ethercat port and operate as EtherCAT® slave devices. Multiple OBSIDIAN® systems can be used in the EtherCAT® chain and interconnected with other Dewesoft EtherCAT®-based data acquisition systems, such as KRYPTON® or IOLITE®.
- Ethernet: The OBSIDIAN® devices can also be connected via the Ethernet network through the available GLAN ports. Multiple OBSIDIAN® devices or other LAN-enabled Dewesoft DAQ devices can be interconnected using standard Ethernet cables and/or our DS-LAN network switches and synchronized via PTP v2.
The versatility of OBSIDIAN® devices is truly remarkable. They can be used in the same way as any other Dewesoft data acquisition system, offering full-speed buffered data acquisition to a computer running our award-winning DewesoftX software. This flexibility transforms any OBSIDIAN® device into an advanced data acquisition system, ready for any online or offline signal processing task.
