2 Port RS422/RS485 Serial Card PCI2S422DB9 StarTech.com

This is a PCI expansion card designed to add two high-speed serial ports to a computer, supporting both RS-422 and RS-485 communication standards. It is ideal for industrial automation, data acquisition, and other applications that require reliable long-distance serial communication. The card is built to minimize conflicts with existing hardware and software, ensuring a smooth installation process. Its plug-and-play compatibility with Windows operating systems makes it easy to set up without needing additional drivers or configuration tools.

The card provides flexibility by allowing each port to be configured as either RS-422 or RS-485, depending on the specific needs of the connected devices. This makes it suitable for a wide range of applications, including connecting to programmable logic controllers (PLCs), sensors, and other industrial equipment. The high-performance design ensures stable and fast data transfer, which is essential in environments where real-time communication is critical.

The card uses a standard PCI interface, making it compatible with desktop computers that have available PCI slots. It is designed for low maintenance, reducing the need for frequent troubleshooting or replacement. The compact form factor allows it to fit into most standard PC cases without requiring additional space or modifications.

Installation typically involves inserting the card into an available PCI slot and connecting the required serial devices using DB9 connectors. No additional power supply is needed, as it draws power directly from the motherboard. Users should ensure that their system has a free PCI slot and that the operating system is compatible with plug-and-play devices.
