Apresentação

Quatech USB 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.

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 device requires a separate port on the PC, with Quatech adapters a single USB port can be used to implement 8 serial devices. In addition, Quatech USB 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 up to 460.8kbps (see specifications for details).
