1 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-mas-
tering 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 with 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 opera-
tions are handled by internal timer pacer clock and trans-
ferred 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, digi-
tal I/O data can utilize simple handshaking data transfer.
