### 2. Key Features

- Multifunction Analog/Digital I/O:
8 isolated analog input channels (16‑bit, 100 kS/s), 2 isolated analog output channels (16‑bit, 100 kS/s), 4 isolated digital inputs, 4 isolated digital outputs, and one 32‑bit counter channel.

- Bus Isolation:
Digital isolators provide complete electrical isolation between the PC bus and external I/O circuits, enhancing noise tolerance and protecting the host system from ground loops and surges.

- High‑Precision Conversion:
16‑bit resolution for both A/D and D/A conversion ensures fine granularity and low non‑linearity error (±16 LSB for input, ±5 LSB for output).

- Flexible Triggering and Synchronization:
Supports software, external trigger, and external clock modes for both input and output. Rising/falling edge selection and 1 µs digital filters are configurable via software.

- Buffer Memory:
Independent 1 k‑word FIFO buffers for analog input and output allow background data acquisition and generation independent of host CPU load.

- Software Calibration:
Full software‑based calibration for analog input/output; user‑defined calibration data can be stored in addition to factory settings.

- Low Profile and Standard PCI Compatibility:
Supplied with interchangeable brackets for both Low Profile and standard PCI slots.

- Comprehensive Software Support:
Compatible with Windows and Linux drivers, MATLAB (ML‑DAQ), LabVIEW (VI‑DAQ), and CONTEC’s C‑LOGGER data logging software. Includes API‑PAC(W32) library for custom application development in Visual Basic, Visual C++, and other Win32 environments.

- Noise‑Resistant Design:
Bus isolation, shielded connector options, and digital filtering minimize interference in industrial environments.

- Data Logging and Visualization:
C‑LOGGER software enables real‑time graphing, data storage, and export to Microsoft Excel without programming.
