RocketPort Serial Hub Si is the ideal solution for any multiport application requiring low-cost, network-expandable peripheral connectivity, including data collection and process control. The RocketPort Serial Hub Si provides Ethernet-based port connections for a virtually unlimited number of serial peripherals. What's more, the RocketPort Serial Hub Si supports RS-232, RS-422, and RS-485 interface standards that are software selectable on each DB9 port! It is ideally suited for retail and industrial automation applications where multiple interface standards are present.With the RocketPort Serial Hub Si, your serial ports can reside outside the server anywhere on your LAN - keeping your server in a secure back-office location while your ports conveniently reside on the work floor! Designed for Intel-based computers, the RocketPort Serial Hub Si provides "native" COM ports that deliver all the performance of an in-server card, with speeds up to 230 Kbps. Based on Comtrol's industry-leading RocketPort AIOPIC processor, Comtrol has taken the concept of in-server serial controllers to its next logical step. A unique software driver technology provides the operating system with the ability to identify and transparently access these ports just as if they were physically installed on an expansion card inside the server. Multi-server port assignment enables ports to be assigned to, and controlled by, different servers-ideal for back-up systems.
