Description
Quatech RS-422/485 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.
The cannot be installed directly into a PC unless specialized adapters
are used.
Quatech RS-422/485 CompactPCI boards
provide 2500 Vrms optical isolation making them ideal for high-noise
industrial environments. The independent ports on the boards are
jumper configurable as either RS-422 or RS-485 in any combination. The
serial ports are accessed via onboard RJ-45 modular connectors,
onboard DB-9 female connectors (2 port boards), or a DB-37 female
connector that can be used with an optional cable providing four DB-25
male ports (4 port boards). 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 921.6 kbps. The
high clock speeds and deep FIFOs greatly reduce CPU overhead, making
the boards ideal choices for heavy multitasking environments.
