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 to be ideal 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 interface between 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.
