Interface card EXSYS EX-44044-2

The EXSYS EX-44044-2 is a PCI-Express interface card that provides four RS-232 serial ports using FIFO 16C550 UARTs and a MosChip chipset. Designed for installation in a PCIe slot on a PC, the card supports reliable serial data transfer for legacy devices, industrial equipment, and point-of-sale systems. It is supplied with an Octopus cable for easy connection to multiple serial devices and includes Windows drivers with WHQL certification for broad compatibility.

Advantages

The card offers four isolated RS-232 channels (managed by FIFO 16C550 UARTs) to ensure stable and buffered serial communication. The MosChip chipset and WHQL-certified Windows drivers improve compatibility with common operating systems. Including the Octopus cable simplifies setup and reduces the need for additional cabling. Its PCIe host interface provides a direct connection to the system bus for consistent data throughput.

Suitable for

• Connecting legacy serial devices to modern PCs
• Industrial control and automation equipment
• Point-of-sale (POS) systems and peripherals
• Data logging and serial communication tasks

How to use

Install the EXSYS EX-44044-2 into an available PCIe slot on the host PC while the system is powered off. Secure the card in the chassis, connect the Octopus cable to the card’s external connector, and attach the serial devices to the cable’s connectors. Boot the PC and install or verify the Windows driver with WHQL certification; the operating system should recognize the four COM ports. Configure port settings (baud rate, parity, data bits, stop bits, and flow control) in your application or device manager according to the connected devices’ requirements.

Recommendations

For stable operation, use shielded serial cables and ensure proper grounding in industrial environments. Verify driver compatibility with your specific Windows version before deployment and test each port with target devices to confirm communication settings.
