Quatech, the performance leader
in device connectivity, makes it
easy to get started

Serial connectivity is the backbone of
many commercial and industrial
applications such as POS networks,
ATMs, bank teller stations and CNC­based production lines. PCI is the
standard for board level expansion
slots in PC-based systems.

Quatech has specialized in quality
data communication products for
over 20 years. We have a proven
failure rate of only .002% after burn­in. And, Quatech’s meticulously
designed boards strictly adhere to
the PCI specification, so you can rest
assured that our products will
consistently function properly in your
systems.

Quatech PCI boards offer extensive
choices for adding serial functionality
to a system using minimal system
resources. They also provide a
peace of mind.

Quatech RS-232 PCI boards utilize a
single PCI slot to provide two, four, or
eight independent asynchronous
serial ports that share a
singleinterrupt. All PCI registers are
properly implemented, so you can be
assured that Quatech boards will be
good citizens on the PCI bus. Serial

port connections are made via DB-9
male connectors, DB-25 male
connectors, or RJ-45 modular
connectors (8 port only).

In addition, industrial surge
suppression may be added as an
option.

The QSC-200/300 (4 port RS­422/485) and ESC-100 (8 port RS-

232) boards implement 16750
UARTs containing 64-byte FIFOs,
while the DSC-100 (2 port RS-232),
DSC-200/300 (2 port RS-422/485)
and QSC-100 (4 port RS-232)
achieve 16550 UARTs. They use a
clock multiplying feature allowing the
boards to achieve data rates as high
as 921.6 kbps.

To maintain maximum signal
integrity, Quatech uses a four-layer
board design. For better protection in
industrial environments, we offer a
surge suppression package option
that applies a surge suppressor to
each line that is capable of sustaining
up to 40A peak, 8 x 20μs transient
surges, a clamping voltage of 30V
and a peak energy dissipation of 0.1
Joules. (Note that implementing the
IND option restricts the board's
speed to 115.2 kbps.)

With Quatech’s five year warranty
and our customer support team
providing expert pre-sales, technical
and customization support -- you
truly have the industry’s most reliable
serial PCI board.
