Moxa CP-118U 8-Port Universal PCI Serial Board
The Moxa CP-118U is an 8-port Universal PCI serial communication board designed to add multiple RS-232, RS-422 and RS-485 interfaces to compatible computers and industrial systems. It is suitable for applications that require several independent serial connections from a single PC, including industrial automation, POS systems, ATM equipment, data acquisition and system integration.
The CP-118U uses a 32-bit Universal PCI interface and supports both 3.3V and 5V PCI buses, providing broad compatibility with suitable PCI and PCI-X host systems. Each of its eight serial ports supports communication speeds from 50 bps to 921.6 kbps, while the 128-byte FIFO and hardware/software flow-control capabilities help maintain reliable multi-port serial communication.

Multi-Port Serial Communication
The CP-118U is designed for environments where a computer must communicate with multiple serial devices simultaneously. Its eight ports can be configured for RS-232, RS-422 or RS-485 communication, allowing one host computer to interface with a variety of serial equipment.
Typical applications include industrial automation, data acquisition, machine control, POS systems, ATM equipment, monitoring systems and industrial system integration. The combination of multiple serial interfaces and high baud-rate support makes the board suitable for installations where several legacy or industrial serial devices must remain connected to a central computer.
Software and Operating System Support
Moxa provides driver support for a broad range of operating systems. Supported platforms include various Windows versions as well as Linux and UNIX operating environments. Current Moxa driver documentation also lists support for newer Windows platforms, including Windows 10, Windows 11 and supported Windows Server releases, subject to the applicable driver version and hardware environment.
Compatibility Considerations
The CP-118U uses a Universal PCI interface rather than PCI Express. It is compatible with suitable 3.3V or 5V PCI/PCI-X systems, but the host computer must have an appropriate PCI-compatible expansion slot. The standard CP-118U uses a DB62 female connector and requires the appropriate Moxa breakout cable or connector accessory to connect individual serial devices.
The CP-118U should not be confused with the CP-118U-I, which adds 2 kV optical isolation, or the CP-118U-T variants designed for wider operating-temperature environments. Select the exact model according to the host interface, environmental requirements and electrical isolation needs.
