Description
Quatech USB to RS-422/485 serial
adapters are easily configured to enable the continued use of legacy
devices without making any changes to the applications written for
them. The adapters enumerate themselves as standard COM ports making
the USB interface completely transparent to software. The ports can
be configured as 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.
Implementing RS-422/485 serial
devices via USB provides many advantages. It enables "plug
& play" capability as well as hot-swapping. And, while in
standard systems each serial port requires a separate port on the
PC, with Quatech adapters a single USB port can be used to implement
8 serial ports or up to 80 RS-422 or 256 RS-485 devices. In
addition, Quatech USB to serial adapters contain deep data FIFOs and
use an accelerated UART clock frequency to further boost data rates.
A single port on the adapter can typically achieve 230.4k bps data
rates, and under certain conditions may be capable of up to
460.8kbps
