PCI Cards

With over 24 years of plug-in DAQ card design and manufacturing experience, Advantech has become a

global leader, providing a full range of industrial data acquisition and control products. The most requested

features are included for industrial and laboratory applications such as monitoring, control, data acquisition and

automated testing.

One Source for All High-precision PC-based Applications

Applications

Complete PCI Card Range to Meet any

Machine and Test Equipment Need

BoardID Switch

BoardID DIP switch helps defines each card’s unique

identity when multiple identical PCI cards have been

installed in the same computer. The BoardID switch is

very useful when you build your system with multiple

identical PCI cards. With the correct BoardID switch

settings, you can easily identify and access each

card during hardware configuration and software

programming.

High Density

High density means there are many input/output

functions in one PCI card. In the past, customers

were forced to buy more than one card to fulfill their

application, but now just one card can achieve their

goals. The biggest advantage of this feature is that it

saves space, allowing more efficient installation.

Auto Calibration

The built-in auto-calibration circuitry corrects gain and

offset errors in analog input and analog output channels

thereby eliminating the need for external equipment and

user adjustments.

Keeping the Output Values after

System Reset

When the system is hot reset (power is not shut off),

Advantech’s DAQ cards with this function can either

retain the last digital (or analog) output values, or return

to its default configuration, depending on jumper

setting. This practical function eliminates danger caused

by misoperation during unexpected system reset.

DMA - Direct Memory Access

A method of transferring data from or to memory at

a high rate without involving the CPU. DMA is the

hardware/software technique that allows the highest

speed transfer of data, to or from RAM. DMA can

provide the means to read or write data at precise times

without restricting the microprocessor’s tasks.
