## Long description

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.

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.
