PCI-1601 and PCI-1602 are 2 port RS-422/485 PCI communication cards that are compatible with the PCI 2.1 bus specification. Both cards provide two optional isolated and EFTsurge protected RS-422/485 ports, and comes with features such as: high transmission speed of 921.6 kbps, optional EFT Surge & isolation protection, windows utility softwareand more. The cards also come with high-performance 16PCI952 UART with a 128-byte FIFO to reduce CPU load. This makes the PCI-1601 and PCI-1602 especially suitable formultitasking environments.PCI-1602 is available with 3,000 VDC optical isolation to protect your PC and equipment against damages from ground loops in harsh environments. To further increase reliability,both boards has EFT surge protection technology, protecting your system from abrupt high voltages up to 2,500 VDC (PCI-1601B and PCI-1602B). Besides, Advantech also providesa convenient utility program called ICOM Tools, to help test the PCI card performance by analyzing the port status. Controlled by easy-to-use menu commands and toolbar buttons,ICOM Tools acts as a PC-based data scope that lets you set a trigger condition, capture the communications data and monitors the signal status. In addition, ICOM Tools is applicableto all series of Advantech ICOM cards.
