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.

Perguntas sobre este artigo

How do I confirm the SI-PEX50054 is operating correctly after installation?

The card uses a PCI-e x1 lane interface compliant with revision 1.0a and supports D1, D2, D3hot and D3cold power states; verify in Device Manager that both serial ports and the parallel port appear without errors.

What brackets and accessories are included with the SI-PEX50054 and what must be sourced separately?

The box contains the PCI-e Multi I/O card, full-size brackets for two serial ports and one parallel port, low-profile brackets for one COM port and one parallel port, a user manual and a driver mini CD; cables for the external ports are not included.

Which version of the SI-PEX50054 should I choose for my system?

The SI-PEX50054 is a single model providing two serial ports and one parallel port over a PCI-e x1 lane; select it when you need both legacy interfaces on a PCI Express slot.
