InLine PCI Multi I/O Controller Card 2 DB9 Serial Ports

The InLine PCI Multi I/O Controller Card InLine 66636I provides two 9‑pin (DB9) serial ports on a PCI interface, designed for reliable wired serial communication with legacy devices and industrial equipment. It is based on the MCS9865 chipset and supports data transfer rates up to 115.2 kbit/s, making it suitable for standard RS‑232 serial connections on systems with a PCI host interface.

Advantages

This controller card offers a compact PCI form factor with two DB9 serial connectors, broad operating system compatibility including DOS 6.22, Windows 2000, XP, Server 2003, Vista and Server 2008, and stable serial performance using the MCS9865 chipset. The card supports standard serial speeds up to 115.2 kbit/s and is suitable for extending legacy serial ports on modern motherboards with PCI slots.

Suitable for

• Connecting legacy RS‑232 devices (modems, POS terminals, barcode scanners)
• Industrial equipment requiring serial communication
• Systems that need additional serial ports via PCI

How to use

Install the card into an available PCI slot on a powered‑off computer, secure it in place, and connect DB9 serial cables to the target devices. Power on the system and install appropriate drivers for the operating system in use; drivers are available for DOS 6.22, Windows 2000, XP, Server 2003, Vista and Server 2008. After driver installation, verify port settings (baud rate, parity, data bits, stop bits, and flow control) in the operating system or application to match the connected device.

Recommendations

Use shielded serial cables and proper grounding in industrial environments to reduce interference. Confirm driver compatibility with your specific OS version before installation and configure port parameters to match the connected equipment for reliable communication.
