PCI-1622CU provides many functions such as four independent RS-422/485 ports with isolation protection, high transmission speed of 921.6 kbps, surge protection and comes with high-performance 16PCI954 UARTs with a 128-byte FIFO to reduce CPU load. These components make your system more stable and reliable. Thus, the PCI-1622CU is especially suitable for multitasking environments. PCI-1622CU has a universal PCI connector that is compatible with both newer 3.3 V signaling systems and the traditional 5 V signaling system. This gives high-compatibility and allows usage in diverse systems. To further increase reliability, the PCI-1622CU offers surge protection from high voltages up to 2,500 V and 2,500 V isolation to protect your PC and equipment against damages DC DC from ground loops in harsh environments. Advantech provides a convenient utility program called ICOM Tools to help test the PCI card’s performance by analyzing the port status. The menu commands and toolbar buttons of ICOM Tools acts as a PC-based data scope that lets you set a trigger condition captures the communication data and monitors the signal status. ICOM Tools is applicable to all series of Advantech ICOM cards.
