- PCI 32‑bit 33 MHz bus (universal key)
- Supported OS: Windows 7/8/10/11, Linux kernel modules
- Software environments: Visual C++, Visual Basic, LabVIEW, gcc

Output Modes:
- Simple Analog Output: Single or multi‑channel output initiated by software command.
- High‑Functional Output: Continuous or triggered output synchronized with sampling clock; supports FIFO or ring buffer memory modes.
- External Trigger Control: Start/stop sampling via opto‑isolated external signals.
