Compatible with most RS232 peripherals, the MANHATTAN Serial/Parallel Combo PCI Card with two external serial DB9 ports is an ideal solution for attaching two serial devices — modems, barcode scanners, printers and more — and a parallel DB25 port through a single PCI card and two open rear expansion slots. Its two high-speed 16C550 UART serial DB9 Com ports fully support PCI IRQ sharing even if accessed simultaneously to help save valuable resources for other expansion cards. The DB25 port with Enhanced Parallel Port (EPP), Standard Parallel Port (SPP) and Enhanced Capability Port (ECP) help support the faster transfer of large amounts of data.
