Interface Card EXSYS EX-45368

The Interface Card EXSYS EX-45368 is a low-profile internal serial interface card designed for PCIe slots, providing instant COM port expansion for PC systems, thin clients, and servers. This PCI I/O-adapter delivers eight high-performance 16C1050-type UART compatible serial ports supporting RS-232, RS-422, and RS-485 communication standards. Each port allows independent interface type selection, offering great flexibility for various industrial and commercial setups. Fully compatible with PCIe Plug-and-Play, the card eliminates traditional IRQ and I/O address configuration issues for seamless integration.

Advantages

This serial interface card features a robust design equipped with a 256-byte FIFO buffer to ensure reliable data transmission without bottlenecks. It supports data bits of 5, 6, 7, and 8, alongside stop bits of 1, 1.5, or 2, accommodating diverse communication protocols. The inclusion of the unique ATTA hardware feature enables automatic RS-485 transceiver turn-around, optimizing data flow. Additionally, the card can supply +5V or +12V power via pin 9 of the male connector to support POS systems, and it includes a low-profile bracket for installation in compact computer cases.

Suitable for

• Adding multiple serial ports to desktop PCs, thin clients, or servers
• Connecting POS systems requiring Power over System capabilities
• Industrial automation and control setups utilizing RS-232, RS-422, or RS-485 devices
• Expanding serial communication in space-constrained computer cases using low-profile brackets

When it may not be suitable

This expansion card is not compatible with computer systems that lack available PCIe slots or systems that require older PCI bus architectures. It is also unsuitable for environments requiring purely wireless communication or non-serial interfaces such as HDMI or dedicated display outputs.

Key specifications

• Dimensions: 115.3 mm width and 64.2 mm depth (low-profile form factor)

How to use

To install the interface card, power down your computer, unplug it from the electrical outlet, and open the computer case. Insert the card firmly into an available PCIe slot, securing it with a screw to the chassis using either the standard or the included low-profile bracket depending on your case size. Close the case, reconnect the power, and boot up the system. The operating system should automatically detect the device through Plug-and-Play technology. Connect your serial cables to the desired ports and configure the interface types and communication parameters in your operating system or device management software.

What to consider before purchase

• Verify that your computer motherboard has an available PCIe slot
• Check your computer case dimensions to determine if the standard or low-profile bracket is needed
• Ensure your connected devices match the RS-232, RS-422, or RS-485 interface standards supported by the card
• Confirm whether your setup requires power delivery over pin 9 for peripherals such as POS systems

Usage recommendations: Handle the interface card by its edges to avoid electrostatic discharge, ensure all drivers are up to date for optimal stability, and securely fasten external serial connections to prevent signal interruption during operation.
