Product information

Description

The InLine PCI Multi I/O Controller Card with 4 DB9 Serial Ports and MCS9865 Chipset is a reliable wired connectivity solution designed to expand desktop computers and industrial systems with essential legacy ports. Utilizing a standard PCI host interface, this controller card enables seamless integration of multiple serial devices into existing computer hardware. Built with industry-standard components, it ensures stable and efficient data communication for various professional and personal computing setups.

Advantages

This controller card simplifies hardware expansion by automatically selecting IRQ and I/O addresses during installation. It supports PCI IRQ sharing, which helps conserve valuable system resources for additional add-on cards. The inclusion of 16C550-compatible UARTs with a 256-byte FIFO buffer on both transmit and receive paths ensures reliable data handling and reduces processor load during continuous operations. Furthermore, the robust driver and operating system compatibility allow for flexible deployment across older and specialized computing environments.

Suitable for

  • Connecting legacy serial devices such as external modems and industrial controllers
  • Integrating 9-pin serial peripherals into desktop computers
  • Upgrading industrial automation and measurement systems
  • Maintaining compatibility with older software environments requiring direct serial port access

When it may not be suitable

This product is not suitable for modern desktop computers that lack traditional PCI expansion slots, as it requires a physical 32-bit PCI bus. It is also not designed for high-speed modern data transfer requirements that exceed standard serial port limitations.

Key specifications

  • Host interface: PCI
  • Chipset: MCS9865
  • Ports: 4 x DB9 serial (RS232)
  • Data transfer rate: Up to 115.2 kbit/s
  • UART: 16C550 compatible
  • FIFO buffer: 256-byte depth
  • Connectivity technology: Wired
  • Compatible operating systems: DOS 6.22, Windows 2000, XP, Vista, Server editions, and Linux kernel 2.6.14 or above

How to use

To install the InLine PCI Multi I/O Controller Card, power off your desktop computer, unplug it from the mains, and open the system case. Insert the card firmly into an available 32-bit PCI slot and secure the bracket to the computer chassis. Close the case, reconnect the power, and turn on the system. Install the appropriate drivers for your operating system to enable the four DB9 serial ports, then connect your desired serial peripherals using standard cables.

What to consider before purchase

  • Verify that your computer motherboard features an available 32-bit PCI slot
  • Check that your operating system is supported by the available drivers
  • Confirm that your peripherals use standard DB9 RS232 serial connections

Ensure the computer is fully powered off and disconnected from the electrical outlet before installing or removing the PCI controller card. Always download drivers from trusted sources to guarantee system stability and compatibility.

Ports & interfaces

Serial ports quantity: The number of serial ports in a computer or peripheral. A serial port is a serial communication physical interface through which information transfers in or out one bit at a time. The term "serial port" usually identifies hardware more or less compliant to the RS-232 standard, intended to interface with a modem or with a similar communication device. In modern computers and peripherals, serial ports have largely been replaced by USBs and other interfaces.
