PCI-1611U is a 4-port RS-422/485 PCI communication card that is compatible with the PCI 2.2 bus specifiction. The PCI-1611U provides many functions such as four independent RS422/485 ports with isolation protection, high transmission speed of 921.6 kbps, and EFT surge protection. PCI-1611U also comes with high-performance 16PCI954 UARTs with a 128-byte FIFO to reduce CPU loading. These compaonents make your system more stable and reliable. Thus, the PCI-1611U is especially suitable for multitasking environments. To improve the performance of the system, the PCI-1611U allows transmission rates up to 921.6 kbps, and to further increase reliability, the PCI-1611U offers EFT surge protectiontechnology, protecting your system from abrupt high voltages up to 2,500 VDC. Besides, Advantech also provides a convenient utility program, ICOM Tools, to help you test the PCI card's performance by analyzing the port status. The easy-to-use graphical user interface of ICOM Tools works like a PC-based data scope that lets you set trigger conditions to capture communication data and monitor a signal's status. ICOM Tools is applicable to all series of Advantech ICOM cards.
