Introduction
SUNIX ComHub UTS series transform your Universal Serial Bus (USB) port into asynchronous RS-232 serial ports for communication with serial devices. The UTS4009PF adapter is compatible with both USB 2.0 and 1.1 specifications and provides serial ports with transfer speed up to 115.2Kbps. It provides a quick, simple and cost-effective way to bring the advantages of data accessibility and mobile solution for kinds of commercial and industrial automation applications.
The UTS4000PF supports USB selective suspend. This feature allows the UTS4000PF to go into power saving mode after it remains in an idle state for a few seconds. The auto saving mode is terminated after UTS4000PF receiving an open port command from system, then UTS4000PF turns back to working mode.
