How to use

Power down the PC, open the case and insert the card into a free standard PCI slot. Secure the card to the chassis and close the case. Boot the system and install the appropriate drivers for your operating system if they are not detected automatically. Connect serial devices to the DB9 ports using standard serial cables and configure port parameters (baud rate, parity, data bits, stop bits) in the operating system or application to match the connected devices.

Recommendations

Use shielded serial cables and proper grounding for industrial environments to reduce electrical interference. Verify driver compatibility with your specific Windows or Linux distribution and test communication settings with the target device before deploying in production.
