The Emerson / Avocent SST Series Multiport Serial Adapters support both a 3.3V or 5V PCI bus with unmatched speed, reliability and superior performance. Designed for ultimate flexibility, Avocent SST multiport serial adapters can support 4 to 64 ports. These intelligent leading-edge adapters support a 3.3V or a 5V PCI bus and offload virtually all serial traffic from your system CPU so servers won't slow down as I/O demand increases. Engineered for reliability, SST 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 for most popular operating systems.
