❓ Frequently Asked Questions - Mini PCIe Serial Card

Q: Does this card require external power?

A: No, the card is powered directly through the Mini PCIe slot. No external power supply is needed.

Q: Is this compatible with my motherboard?

A: This card requires a standard Mini PCIe slot (PCIe 2.0 Gen 1 or newer). Please verify your motherboard has an available Mini PCIe slot before purchasing. It's compatible with most embedded boards, mini-ITX motherboards, and server platforms.

Q: Can I use all 4 ports simultaneously?

A: Yes, all 4 RS-232 ports can operate simultaneously at full speed (up to 921.6Kbps per port) without performance degradation.

Q: What cable type do I need for RS-232 connections?

A: We recommend using twisted-pair cable or shielded cable for optimal signal integrity. Standard DB9 serial cables are compatible with the RS-232 ports.

Q: Do I need to install drivers?

A: Yes, drivers are required for proper operation. Download the latest driver package from the link above. The driver supports Windows (XP through 10, Server editions) and Linux (kernel 2.6.27 and newer).

Q: What is the maximum cable length for RS-232?

A: RS-232 standard supports cable lengths up to 15 meters (50 feet) at maximum baud rate. For longer distances, consider using RS-422 or RS-485 converters.

Q: Does this card support hot-swapping?

A: No, Mini PCIe devices are not designed for hot-swapping. Please power down your system before installing or removing the card.

Q: What warranty is included?

A: This product comes with a standard manufacturer warranty. Please contact us for specific warranty terms and support.

💡 Pro Tip: Ensure your system has an available Mini PCIe slot before installation. Check compatibility with your operating system version for optimal performance.
