Two Serial and One Parallel Port

This Syba SI-PEX50054 card adds two serial ports and one parallel port through a PCI Express x1 lane interface. It targets users who need to connect legacy industrial equipment, older printers or specialised instruments to a modern motherboard. The board complies with the PCI-e Base Specification Revision 1.0a and supports D1, D2, D3hot and D3cold power states.

Brackets for Standard and Low Profile Slots

The package includes a full size bracket for the two serial ports, a full size bracket for the parallel port, plus low profile brackets for one COM port and one parallel port. Installers choose the bracket that matches their chassis and secure the card in any available PCIe x1 slot. A driver mini CD and user manual are supplied for operating system setup.

Sustained Legacy I/O Throughput

Under continuous use the controller maintains stable communication with attached serial and parallel devices without relying on burst performance. The 100 MHz differential PCI-e common reference clock keeps timing consistent during long data transfers. The card is not suited for builders who need high speed storage or modern peripheral interfaces.
