The PCI-1800 series is a family of high performance data acquisition board for PC with PCI bus. It features a continuous, 330KHz for low gain (44KHz for high gain), gap-free data acquisition under DOS and Windows. The PCI-1800 family has the same architecture and has, two 12-bit D/A output channel, 16 digital input channels,16 digital output channels. The PCI-1802H, PCI-1802L provide 32 single-ended or 16 differential inputs. The -H means high gain model and the -L means low gain model.

The scan function of PCI-1800 is called "Magic Scan". The variable channel scan function is found in some famous data acquisition board. Compared to Variable channel scan, the Magic Scan improves many functions to meet the demand of the high end user. The Magic Scan  mechanism not only scans the different input channels at vastly different rates, but also at different gains. Even in multi-channel scan, the sampling rates can maintain at 330KS/s.

The board is equipped with 8K samples hardware FIFO which reduces data overflow issues.

Includes one CA-4002 D-Sub connector.
