OS650 PCI/PCI-X 64 bit 3.3/5V Eight Port Intelligent Serial Adapter Board/Card

QS65O PCI/PCI-X 64 bit 3.3/5V Four  Port Intelligent Serial Adapter Board/Card

More than 8 Ports

These intelligent serial I/O adapters use less than 1% system load so servers won't slow down as you run more applications, attach more devices or service more users. They do not use an interrupt (IRQ).

Designed for ultimate flexibility, multiport universal serial adapters are available from 4 to 128 ports. These intelligent leading-edge universal adapters support a 3.3V (PCI-X 64 bit) or a 5V PCI bus which offload virtually all serial traffic from your system CPU so servers won't slow down as I/O demand increases. Engineered for reliability, SuperSerial adapters include 15,000 volt surge suppression on every pin of every port eliminating blown ports from transient electrical spikes. With unmatched speed, surge suppression and superior performance, these intelligent adapters provide cost-effective, reliable connections to serial devices under most popular operating systems. Serial adapters used in conjunction with Port Modules and Connector Panels offer flexible distance options. Multiport Serial Adapters offer a variety of choices for Retail/POS, Multiport and Expandable connectivity.
