Product Description:
We
designed the intelligent PCI-1625/PCL-844+ 8-port RS-232 or RS-422
interface card 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-1625/PCL-844+ cards for a total of 32 ports in any AT/lSA bus-based
PC.
The PCI/1625/PCL-844+ card has an on-board RISC processor that takes
over the communications load from the host PC. When you are processing
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-1625/PCL-844+ 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.
