Introduction
The intelligent PCI-1625U 8-port RS-232 or RS-422 interface card was designed for lab and industrial applications where a PC needs to communicate with terminals, modems, or
other instruments. RS-422 applications use the optional Opt-8F/8Z 8-port RS-232 to RS-422 converter, shown on the following page. You can install up to four PCI-1625U cards for
a total of 32 ports in any PCI bus-based PC.
The PCI-1625U card has an onboard RISC processor that takes over the processing load from the host PC. When you are transferring large amounts of data from multiple ports,
servicing the interrupts alone consumes a large percentage of the capacity of your computer's CPU. The PCI-1625U serves as a high speed, dedicated interrupt processor. Its CPU
directly controls the board's CD180 RISC-based UART, guaranteeing 921.6 kbps performance of over eight high speed data ports.
The PCI-1625U is virtually a self contained computer. It contains 512 KB of dual-port RAM which you can use to store and run programs. The dual-port RAM maps into the host
system's address space to give you the fastest possible data transfers between the PCI-1625U and PC memory.
When the PCI-1625U initializes, it downloads the driver software (which functions like a PC's BIOS) into its on-board SRAM. This improves performance and makes version upgrading
easy. No hardware redundancy!
