RS-422/485 Serial CompactPCI Card:
QSCP-200/300 Four Port

Quatech RS-232 CompactPCI boards are dedicated serial boards designed specifically for CompactPCI systems. Though electrically similar to standard PCI boards, CompactPCI boards are made to be used in specialized enclosures designed to provide both superior protection against environmental hazards and easy access for rewiring, replacing, or exchanging boards.

They cannot be installed directly into a PC unless specialized adapters are used.

Quatech RS-232 CompactPCI boards provide 2500 Vrms optical isolation making them ideal for high-noise industrial environments.

The serial ports are accessed via onboard RJ-45 modular or standard DB-9 male connectors on the card edge.

Serial ports are implemented with 16750 UARTs containing 64-byte FIFOs. They also use a clock-multiplying feature allowing them to achieve data rates as high as 460.8 kbps. The high clock speeds and deep FIFOs greatly reduce CPU overhead, making the boards ideal choices for heavy multitasking environments.
