High Speed USB Serial Adapters

Standard serial ports via USB 2.0 without replacing peripheral hardware
or application software

Connect serial peripherals with USB 2.0
Serial Adapters
For over 20 years, Quatech has been
known to help you Connect with
Reliability. As we continue in the race to
become the industry leader, our high
performance device connectivity line
expands with the new high speed USB
2.0 Serial Adapters. The next generation
Quatech USB Serial Adapter hits speeds
of up to 921.6 kbps, 1024-byte FIFO and
hardware and software flow control.

If speed, expansion and support are
what youre looking for in a USB Serial
Adapter, think Quatech.
You can now broaden the range of
external peripherals used on your
computer at higher speed rates than the
USB 1.1 series, with the introduction of
the High Speed USB 2.0 Serial
Adapters. The USB 2.0 has more
bandwidth that allows higher data rates
on the serial ports for more efficiency.
The new High Speed USB Serial
Adapter line gives your laptop or
workstation the ability to communicate
between a USB port and up to eight RS-
232, RS-422, or RS-485 serial
peripherals. It adds the COM port(s) via
its USB connection and is compatible
with new and legacy RS-232 or RS-
232/422/485 devices. The USB Serial
Adapters are the ideal solution for a
variety of industries and applications
including banking, retail and industrial
automation where PCs have a
significantly shorter lifecycle than the
peripherals that use them.

Quatech USB Serial Adapters
enumerate themselves as standard
COM ports that are compatible with all
standard RS-232 or RS-232/422/485
devices and software created for them.
With the industrial surge suppression
“IND” option, you can safeguard the USB
Serial Adapter. The “IND” option is ideal
for implementing USB-to-serial networks
in factories, power plants and other
potentially harsh industrial
environments. USB 2.0 is fully
compatible with USB 1.1 devices. The
older devices work with the new bus,
and vice versa.
The 400 Series models introduce the
software-selectable RS-232/422/485
(Multi-Electrical Interface or MEI). The
MEI capability is available on all ports at
the click of a mouse. LEDs visually tell
you which ports are using which
protocol, so go ahead, mix and match.
