Embedded High Speed USB 2.0
Serial Adapters for custom enclosures
If you’re looking to seamlessly connect
multiple serial peripherals via a single USB
port in a custom enclosure, try Quatech’s
Embedded High Speed USB 2.0 Serial
Adapters.  These reliable units use the same
technology as our external products but
enable manufacturers and integrators to
easily incorporate multiple serial interface
devices such as keypads, displays, card
readers and printers, into custom enclosures
that lack native serial support.  
As a special convenience, Quatech USB
Serial Adapters provide standard serial ports
without requiring the replacement of
peripheral hardware or application software.  
Available with one, four or eight independent
ports, the small footprint boards have built-in
surge suppression at each serial port,
necessary for maximum reliability and
robustness.  Mounting holes allow easy
installation into cabinets and kiosks.  For
maximum flexibility, each port on the 400
models can be configured as RS-232, RS-
422 or RS-485 in any combination, meaning
a single adapter can be used to implement
multiple full-duplex and half-duplex multi-drop
networks.  
Connect serial peripherals with USB
2.0 Serial Adapters
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 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 embedded USB Serial Adapter gives
you 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. USB Embedded
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.  
Building on the success of the previous
versions, the new generation of Quatech USB
Serial Adapters hit speeds of up to 921.6
kbps, 1024-byte FIFO and hardware and
software flow control.  
Quatech Embedded 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 standard, you can
safeguard the USB Serial Adapter when
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 (MEI or
Multi-Electrical Interface). 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.
