Frequently Asked Questions
What is a PCIe serial port card used for?
A PCIe serial port card adds RS-232 connectivity to computers lacking native serial ports. It's essential for connecting legacy industrial equipment, barcode scanners, medical devices, and other serial peripherals to modern systems with PCI Express slots.
Can I use this card with legacy parallel printers?
Yes. The single parallel port on this SIIG expansion card supports traditional parallel printers and devices. Combined with the dual serial ports, it provides comprehensive legacy device support in a single card.
Do I need external drivers for the SIIG PCIe card?
Most modern operating systems recognize this card automatically. However, SIIG provides optimized drivers for Windows and Linux to ensure full functionality and performance optimization for your specific system configuration.
How many serial devices can I connect to this card?
This card provides two independent RS-232 serial ports, allowing you to connect two serial devices simultaneously. Each port operates independently with full serial communication capabilities.
