The industry's FIRST PCI Express 2S1P Multiport adapter to support 1x, 4x, 8x, 16x Lane bus slots DSP1000 Introducing the industry's FIRST and ONLY add-on 2 serial (16950) + 1 parallel (EPP/ECP compatible) adapter for PCI Express. This cutting edge design permits a quick installation of 2 of RS232 serial + 1 of parallel port to any brand of computer system with a single PCI Express expansion slot.

The industry's FIRST 2S1P Multiport adapter to support 33 MHz, 66 MHz, 100 Mhz, 133 Mhz PCI / PCI-X bus speeds without compromise STOP slowing down your PCI-X bus to 33 MHz !
DSP64000 State of the art design operates at host bus speeds 2 (Dual) Serial Port RS232 I/O + 1 Parallel Port Card for 3.3 / 5 volt PCI / PCI-X 32 or 64-Bit expansion slots. Suitable for Low / Standard height mounting.Compatible with all IBM, HP, Compaq, Dell, Intel Servers Server
systems are being manufactured with limited or no serial / parallel ports. In
addition these servers are typically offered with PCI-X expansion slots capable
of supporting 66, 100 or 133 MHz bus speeds. To date, the only method of adding
serial or parallel ports has been to plug-in 33 MHz, 32-Bit I/O cards.
Installing a 32-bit expansion card will automatically slow down the PCI-X bus
speed to 33 MHz PCI mode, which causes a concern for the demanding customer. To
make matters worse, many server motherboards utilize 2 or more PCI-X expansion
slots to a common PCI-X bus.
In this configuration a 66 MHz or faster network adapter or similar
add-on circuit board will be forced to operate at 33 MHz to accommodate the
slower 32-bit expansion card.
