PCI-1434E

PCI-1434E is a general-purpose communication card, intended for PCI Express bus. The card provides four isolated ports (two RS-232 and two RS-422/485).

PCI-1434E card is based on MCS9904CV controller (manufacturer ASIX Electronics Corp.) that provides PCI Express bus interface, four efficient UARTs (similar to the 16C950 standard) with DMA FIFO 2x 128B in one circuit.

The first two ports at the PCI-1434E card lead to the D-Sub 9 connectors located on the card mounting bracket, the other two ports are accessible via the expansion card PCI-1023E, fitted with the interface circuits located in the next slot. The RS-232 ports provide full modem control signals and standard pin layout.

Ports provide the optical isolation. Optional surge arresters (ESD-X4) can be added to protect isolation barrier against breakdown caused by induced overvoltage.
For more information see safety guidelines for preventing overvoltage damage.

Useful feature are LED indicators on the card mounting bracket (a pair for every port) providing a comfortable check of the line activity.
