Interface Card EXSYS EX-44343

The Interface Card EXSYS EX-44343 is a reliable PCIe expansion solution designed to add essential legacy ports to modern computer systems. This PCI-Express I/O adapter provides high-performance 16C550-type UART compatible RS-232 serial ports and one Parallel Centronics EPP/ECP port, making it ideal for connecting a wide range of peripheral devices to a PC, thin client, or server via the PCI Express bus. Featuring a compact form factor and broad operating system compatibility, this card integrates seamlessly into existing desktop and server setups while ensuring stable data communication.

Advantages

This interface card offers a convenient Plug-and-Play installation process that eliminates manual IRQ and I/O address configuration issues. It includes a LowProfile bracket, enabling installation in small computer chassis with a maximum height of 8 cm. Additionally, the card is capable of supplying +5V and +12V power via pin 9 on the male serial connectors, which is particularly useful for powering compatible POS systems directly through the interface.

Suitable for

• Connecting legacy serial devices such as barcode scanners, receipt printers, and industrial equipment
• Expanding server or workstation connectivity with additional COM and LPT ports
• Integrating into small form factor PC chassis using the included LowProfile bracket
• Powering compatible POS systems using the Power over System feature on pin 9

When it may not be suitable

This interface card is not suitable for systems lacking an available PCIe slot. It is also not designed for high-speed modern data networking tasks that require high-bandwidth interfaces beyond standard serial and parallel communication rates.

Key specifications

• Host interface: PCIe (PCI Express 1.0a compliant)
• Ports: 4x 9-Pin D-SUB male serial ports, 1x 25-Pin D-SUB female parallel port, 1x 4-pin internal power connector
• UART compatibility: 16C550 with 16-byte FIFO buffer
• Supported data transfer rates: Up to 0.1 Mbit/s
• Dimensions: 120 mm width, 66 mm depth
• Weight: 550 g
• Certifications: CE, FCC, ROHS, WHQL

How to use

Power down your computer and disconnect it from the power source before opening the chassis. Insert the EXSYS EX-44343 card into an available PCIe slot on your motherboard and secure it firmly. If you are using a compact desktop case, replace the standard bracket with the included LowProfile bracket prior to installation. Close the computer case, power on the system, and install the appropriate drivers for your operating system. The operating system will automatically handle I/O address settings and resource allocation.

What to consider before purchase

• Verify that your computer motherboard has an available PCI Express slot
• Check the physical dimensions and chassis size to ensure the standard or LowProfile bracket is required
• Confirm operating system compatibility with your current desktop or server environment
• Check if your peripheral devices require power over serial pin 9

Usage recommendations: Always ensure the computer is fully powered off and unplugged before installing or removing internal expansion cards. Handle the interface card by its edges to avoid electrostatic discharge damage to sensitive components.
