xRSUNI & xRSUNI-LP series Cost-effective solution to add 2, 4 or 8 high performance serial ports, universal bus, standard & low profile for PCI & PCI-X computers - 8580 xRSUNI range

The new range of universal PCI serial multi-port boards from ACKSYS combines high performance, ease of use, robustness at very competitive prices. This multipurpose range includes 2, 4 and 8 channel boards for RS232, RS422 or RS485. PERFORMANCE ... Featuring state-of-the-art communication controllers (UARTS), the xRSUNI range reduces host CPU loading by up to 75% compared with existing PCI boards. This level of performance is made possible by the full-scale PCI interface integrated in the UARTS, unlike traditional architectures. The 128 byte per channel FIFO buffer memory means the boards can manage multiple communication lines at much higher rates than traditional boards, and ensures the reliability of received data. A high resolution baud rate generator can handle custom transmission rates besides the standard rates (up to 1.8 Mbps). UNIVERSALITY ... The xRSUNI range offers ease of use in all PCI based computers (PCI & PCI-X) regardless of the bus power supply (+3.3VDC / +5VDC) and whether the form factor is standard profile or low profile MD1). SECURITY ... In RS485 mode, line turn-around is usually software-controlled, a fact which often leads conflicts. The xRSUNI board performs automatic line turn-around to guarantee optimal performance in RS485 mode, independently of the baud rate or operating system. LIFETIME WARRANTY
