YDLan PCIe Parallel Port Card DB25 16C550C 9805

SKU CH-R899-J3W4R

Adds a DB25 parallel port via PCIe x1 for printers, programmers and scanners with 16C550C UART and broad OS support

  • Adds a DB25 parallel port via PCIe x1
  • Connects legacy printers, scanners and programmers
  • Works with Windows, macOS 10.5 and Linux
  • 16C550C UART with 16-byte FIFO buffer
  • Fits x1, x4, x8 or x16 PCIe slots

PCI Express Parallel Port Card

This PCIe x1 add-on card adds a single DB25 parallel port to a modern system. It is built for users who must connect legacy printers, programmers or scanners that still rely on an LPT interface. The 16C550C compatible UART provides a 16 byte FIFO for reliable data transfer. Installation fits any PCIe x1, x4, x8 or x16 slot.

Replaces Missing Onboard LPT Port

The card restores a parallel connection on motherboards that no longer include a built-in LPT header. It is worth fitting when existing USB-to-parallel adapters cannot satisfy timing-sensitive programmers or industrial equipment. The 9805 controller handles SPP, PS2, EPP and ECP modes under IEEE 1284 without jumpers. BIOS assigns the I/O address and IRQ automatically.

Sustained Operation With Legacy OS Support

The 32-bit bus design complies with PCI Express 1.1 and PCI 2.1 specifications for stable throughput during long print or programming jobs. Supported operating systems range from DOS and Windows 95 through Windows Server 2008 32/64-bit, plus Linux and Mac OS/X 10.5. No hardware switches mean configuration stays consistent across reboots. The low-profile bracket suits compact chassis.
