Introduction

The PCI-7200/cPCI-7200 is PCI/CompactPCI form factor high-speed digital I/O card, it consists of 32 digital input channels, and 32 digital output channels. High performance designs and the state -of-the-art technology make this card suitable for high-speed digital input and output applications.

The PCI-7200 performs high-speed data transfers using bus -mastering DMA via 32-bit PCI bus architecture. The maximum data transfer rates can be up to 12MB per second. It is very suitable for interfacing high-speed peripherals and your computer system.

Several different digital I/O operation modes are supported:

1.Direct Program Control: the digital inputs and outputs can be accessed and controlled by its corresponding I/O ports directly.

2.Timer Pacer Mode: the digital input and output operations are handled by internal timer pacer clock and transferred by bus mastering DMA.

3.External Clock Mode: the digital input operations are handled by external input strobe signal (I_REQ) and transferred by bus mastering DMA.

4.Handshaking: through REQ signal and ACK signal, the digital I/O data can have simple handshaking data transfer.
