产品描述
The OMG-ULTRA-SIO provides the PC with two isolated RS422/485 Asynchronous s to data collection and other devices. Isolation is important in installations where the equipment connected to the PC is either located far from the host system, or on a different power transformer circuit. The optical isolation feature of the OMG-ULTRA-SIO-I eliminates the risk of ground loop current, a commonly neglected and misunderstood phenomenon which leads to data errors and destruction of communications equipment. Individually selectable addresses and extended “AT” interrupts allow for seamless integration into Windows and OS/2 systems. The OMG-ULTRA-SIO appears to the host system as a standard COM: port requiring no special drivers or additional software.

Software
WIN XP/Vista/7 drivers are included as well as support for Linux. The drivers provide IRQ sharing, advanced UART support and serial diagnostic utilities.
