Interface Card Exsys EX-44088

The Interface Card Exsys EX-44088 is an internal serial interface card equipped with a PCIe host interface and a serial output interface, designed to provide instant COM port expansion via the PCI Express Bus. Featuring 8 high-performance 16C1050-type UART compatible RS-232 serial ports, this PCI-Express I/O adapter ensures reliable and efficient serial communication. It includes a FIFO buffer of 256 B for enhanced data handling and supports flexible power delivery by providing +5V and +12V to the 9-pin male serial connector for POS systems.

Advantages

This internal serial interface card offers seamless integration with personal computers, thin clients, and servers thanks to its fully Plug-and-Play compatible design. It effectively eliminates traditional configuration issues related to IRQs and I/O addresses. The inclusion of eight high-performance UART compatible ports allows multiple devices to be connected simultaneously, while the built-in 256-byte FIFO buffer ensures smooth data flow without bottlenecks. Additionally, the integrated Power over System capability supplies necessary voltage directly through the serial connectors, simplifying setups for point-of-sale applications.

Suitable for

• Expanding COM ports on desktop PCs, thin clients, and servers
• Connecting RS-232 serial peripherals in professional environments
• POS (Point of Sale) systems requiring power over the serial interface
• Industrial or office setups needing reliable multi-port serial communication

When it may not be suitable

This interface card is not compatible with systems that lack an available PCI Express (PCIe) expansion slot. It is also unsuitable for devices that require legacy PCI connections rather than PCIe, or for setups that do not utilize RS-232 serial communication protocols.

How to use

To install the interface card, power down your computer or server, disconnect the power cord, and open the system chassis. Insert the card firmly into an available PCI Express slot and secure the bracket to the computer case. Once the hardware is installed, close the chassis, reconnect the power, and boot up the system. The operating system should automatically detect the device as a Plug-and-Play component. Connect your RS-232 serial cables to the 9-pin ports on the card and install any required drivers specific to your operating system version.

What to consider before purchase

• Verify that your computer, thin client, or server has an available PCIe slot
• Check compatibility with your specific Windows operating system version
• Ensure your peripheral devices use the RS-232 serial interface
• Determine if your setup requires power over the serial connector for POS applications

Usage recommendations

Always ensure the computer is fully powered off and disconnected from the mains before installing or removing the interface card. Handle the card by its edges to avoid electrostatic discharge damage to sensitive electronic components.
