Multiport Bus Cards PCI Express
Today, many servers and industrial computers are equipped with a PCI-X bus. In such systems, there is often a shortage of "traditional" PCI slots. MOXA PCI Express boards add RS-232/422/485 ports to the computer, leaving PCI slots free for connecting other peripherals. Multiport PCI Express cards are made in the Low Profile format and can be installed in both classic and compact cases .
