Perle's SPEED LE PCI Parallel Card family enables users to add parallel ports supporting the full IEEE 1284 parallel port standard to their PCs or servers. These universal PCI cards meet the PCI and PCI Express standards that have been adopted by PC server manufacturers and are available in standard and low profile form factors. Serial-parallel PCI combo cards are also available for those applications that require both serial RS232 and parallel ports on a single PCI or PCI Express card interface.

SPEED LE PCI cards are certified with 32 and 64 bit versions of Windows, Vista and Linux operating systems.
