PCI-1612 is a 4-port RS-232/422/485 PCI communication card that is compatible with the PCI 2.1/2.2 bus specification and offer transmission rates up to 921.6 kbps. PCI-1612 comes with high-performance 16PCI954 UARTs with a 128-byte FIFO to reduce CPU load. These components make system more stable and reliable. Thus, the PCI-1612 is especially suitable for multitasking environments. PCI-1612B, PCI-1612U and PCI-1612CU provide four optional surge protected RS232/422/485 ports and also offer four independent RS-232/422/485 ports. PCI-1612U and PCI-1612CU have universal PCI connectors that are compatible with both newer 3.3 V signaling systems and the traditional 5 V signaling system. This gives highly-compatibility and allows usage in diverse systems. To further increase reliability, PCI-1612B, PCI-1612U and PCI-1612CU offers surge protection for high voltages up to 2,500 VDC. Meanwhile, PCI-1612CU provides 2,500 VDC isolation to protect your PC and equipment against damages from ground loops in harsh environments. Advantech also provides a convenient utility program called ICOM Tools to help test the PCI card 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, capture the communications data and monitor the signal status. ICOM Tools is applicable to all series of Advantech ICOM cards.
