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.
