Comtrol RocketPort Plus uPCI Quad/Octa 422 interface cards/adapter

Comtrol 99400-8 RocketPort Plus uPCI Quad/Octa 422, RS-422 communications support, RS-422 communications support The Comtrol RocketPort Plus uPCI 422 Quad/Octa Bulk package contains fifty (50) serial port expansion cards that are compatible with all current 3.3 and 5.0 Volt PCI bus architectures. Depending on the serial cables, purchased separately, each card provides four or eight "native" serial ports utilizing a single PCI card slot. The serial ports support RS-422 serial communications at speeds up to 921 Kbps. Every RocketPort serial card features the high-performance RocketPort ASIC chip, consisting of a dedicated 44MHz processor that minimizes host CPU utilization and larger transmit-and-receive buffers than those of 16550 UART chips used in standard PC serial ports and low-end serial cards. RocketPort ASIC technology enables these cards to outperform other serial expansion cards by handling the transmission of large amounts of data more reliably and efficiently. Additionally, RocketPort products do not require the assignment of interrupts, simplifying installation and eliminating conflicts with other server cards. The product complies with the European RoHS Directive 2002/95/EC.
