Quatech RS-422/485 asynchronous serial PCMCIA cards are an ideal solution
for adding additional ports to full and half duplex multi-drop systems.
Because they share electronic fundamentals with native bus architectures
such as PCI and ISA, they function exactly like standard COM ports and
can be addressed as such by most application software. In addition, their
small size and the fact that the card itself can be left inside the computer
at all times, make them practical choices for the most ported portable
systems.
Quatech RS-422/485 serial PCMCIA cards provide many unique features that
make them particularly robust and easy to use. Each of the ports is configurable
as RS-422 or RS-485, and on multiport cards any combination of RS-422
and RS-485 ports can be used. For high performance is heavy multi-tasking
environments, the cards are implemented with 16750 UARTs containing 64-byte
FIFOs. This along with Quatech's special clock-multiplying feature enables
data transfer rates as high as 921.6 kbps.
They also provide a unique Auto-Toggle mode by which the hardware itself
can regulate data flow in Half-Duplex mode by only driving lines while
actively transmitting--providing increased speed and convenience over
the older software controlled method. In addition, the cards also conserve
system resources with their low power requirements that maximize battery
life. They also have selectable and shareable interrupts, further extending
a portable or handheld system's limited resources. And their multi-platform
operating support makes them the single practical choice for a diverse
fleet of portable systems.
