## Summary description

The EXSYS EX-45368 is a low-profile internal serial interface card designed for PCIe slots. It features a FIFO buffer of 256 B and supports data bits of 5, 6, 7, and 8, with stop bits of 1, 1.5, or 2. This card is ideal for PC applications, certified with CE, and offers reliable performance in serial communication. Its compact dimensions of 115.3 mm width and 64.2 mm depth make it suitable for various setups, weighing only 1.1 kg.

## Long description

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
PCIe bus interface compatible with Plug-and-Play
Eight independent serial ports supporting RS-232, RS-422, and RS-485
16C1050-type UART compatible with a 256-byte FIFO buffer
Configurable data bits (5, 6, 7, 8) and stop bits (1, 1.5, 2)
RS-485 Auto Transceiver turn around via ATTA hardware
Power over System capability supplying +5V and +12V via pin 9
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.
