# Ethernet/PCIe DAQ Board

This reference manual describes [hardware and software architectures and interfaces](/axsun-knowledge-base/ref-manual/gigabit-ethernet-daq-board/architecture-and-interfaces.md), [basic operation](/axsun-knowledge-base/ref-manual/gigabit-ethernet-daq-board/basic-operation.md), [advanced features](/axsun-knowledge-base/ref-manual/gigabit-ethernet-daq-board/advanced-operation.md), and [troubleshooting](/axsun-knowledge-base/ref-manual/gigabit-ethernet-daq-board/edaq-troubleshooting.md) for the **Axsun Ethernet/PCIe Data Acquisition (DAQ) Board**.

Performance specifications and other quantitative characteristics of the Ethernet/PCIe DAQ Board hardware can be found online in its [datasheet](https://downloads.axsun.com/public/datasheets/Axsun_OCT_DAQ_datasheet.pdf).

The Axsun Ethernet/PCIe DAQ Board is an integral component of the [**Axsun Integrated Engine**](/axsun-knowledge-base/guides/integrated-engine.md), which also includes a SS-OCT Laser, K-clock, Balanced Photoreceivers, and other optional components. Detailed information for these other components in the Axsun Integrated Engine are found in related documentation accessible from the Table of Contents in the left sidebar.
