Introduction

The PCI-7200, cPCI-7200, and LPCI-7200S are PCI/CompactPCI/Low profile PCI form factor high-speed digital I/O cards, consisting of 32 digital input channels, and 32 digital output channels. High performance design and 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 the 32-bit PCI bus architecture. The maximum data transfer rates can be up to 12MB per second—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 an external input strobe signal (I_REQ) and transferred by bus mastering DMA.

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