❓ Frequently Asked Questions
Q: Is this card compatible with my system?
A: The IO-mPCE352-2S works with any system that has a Mini PCI-Express slot and supports Windows XP/Vista/7/8/8.1/10, Windows Server 2003/2008/2012, or Linux 2.6.27 and newer. It's commonly used in embedded PCs, industrial computers, thin clients, and compact servers.
Q: Do I need to install drivers?
A: Yes, drivers are required for proper operation.
Q: What cable do I need to connect RS-232 devices?
A: The card features pin headers for RS-232 connections. You'll need either a header-to-DB9 adapter cable or a custom cable that matches your specific device connector. Standard DB9 serial cables can then be used to connect your RS-232 equipment.
Q: Can I use both ports simultaneously?
A: Yes, both RS-232 ports operate independently and can be used at the same time. Each port has its own 256-byte FIFO buffer and supports full-duplex communication at speeds up to 921.6kbps.
Q: What is the maximum cable length for RS-232?
A: RS-232 standard recommends a maximum cable length of 15 meters (50 feet) at 19.2kbps. For higher baud rates like 921.6kbps, shorter cables (3-5 meters) are recommended for reliable communication. Cable quality and environmental interference also affect maximum distance.
Q: Does this card require external power?
A: No, the card is powered entirely through the Mini PCI-Express slot. It draws minimal power and is suitable for low-power embedded systems and industrial applications.
Q: Is the card suitable for industrial environments?
A: Absolutely. The IO-mPCE352-2S is designed for industrial use with 15kV ESD protection and an extended operating temperature range of -40°C to 85°C, making it ideal for harsh environments, factory automation, and outdoor installations.
Q: What COM port numbers will be assigned?
A: COM port numbers are assigned automatically by your operating system during driver installation. You can view and modify port assignments through Device Manager (Windows) or system configuration tools (Linux). The ports typically appear as the next available COM numbers in your system.
Q: Can I use this card with RS-485 or RS-422 devices?
A: This card is designed specifically for RS-232 communication. For RS-485 or RS-422 applications, please check our other serial expansion cards that support those protocols.
Q: What warranty is included?
A: All Lekuo products come with a standard manufacturer warranty. Please contact our support team for specific warranty terms and technical assistance.
