Interface Card Exsys EX-45364 Internal Serial

The Exsys EX-45364 is an internal serial interface card designed for PC, thin client, and server use. This PCI I/O-adapter provides four high-performance 16C1050-type UART compatible serial ports, supporting RS-232, RS-422, and RS-485 communication standards. It allows for flexible data configurations and instant COM port expansion via the PCIe Bus with full Plug-and-Play compatibility.

Advantages

The interface card offers significant flexibility by allowing users to select an independent interface type for each of the four ports. It features RS-485 Auto Transceiver turn around supported by the unique ATTATM hardware feature, preventing configuration issues related to IRQs and I/O addresses. Additionally, it can supply power via pin 9 to support POS systems, and includes a Low Profile bracket to accommodate smaller computer cases.

Suitable for

• Expanding COM ports on PCs, thin clients, and servers
• Connecting POS systems requiring Power over System functionality
• Industrial and commercial serial communication setups using RS-232, RS-422, or RS-485 protocols

When it may not be suitable

This internal expansion card is not suitable for computers lacking an available PCIe slot. It is also not designed for consumer devices that do not support standard serial communication protocols or internal hardware installation.

Key specifications

• Host interface: PCIe
• Serial communication standards: RS-232, RS-422, RS-485
• UART type: 16C1050-compatible
• Number of serial ports: 4
• Dimensions: 68 mm width, 110 mm depth
• Weight: 800 g
• Power delivery: +5V and +12V via pin 9 on male connector

How to use

To use the interface card, power off your computer, open the case, and insert the card into an available PCIe slot. Secure the card using the standard or included Low Profile bracket depending on your computer case size. Once the computer is powered back on, the operating system will recognize the hardware via Plug-and-Play, and you may install any required drivers to configure the individual serial ports for RS-232, RS-422, or RS-485 operation as needed.

What to consider before purchase

• Verify that your computer, thin client, or server has an available PCIe slot
• Confirm compatibility with your operating system and specific serial device requirements
• Check whether your setup requires standard installation or the included Low Profile bracket

Usage recommendations: Ensure the computer is completely disconnected from power before installing or removing the internal interface card. Configure each port's interface type carefully according to your connected peripheral specifications to ensure stable communication.
