PCI 60806A Driver: Complete Installation Guide, Troubleshooting, and Compatibility

Introduction: What is the PCI 60806A?

The PCI 60806A is a legacy multi-port serial card, typically manufactured by brands like MosChip, MCS9865, or SUNIX. It allows a desktop computer to add up to 4, 6, or 8 additional RS-232 (serial) ports via a single PCI slot. These cards are essential in industrial automation, POS systems, legacy medical equipment, network device configuration, and embedded systems where serial communication is still critical.

The 60806A chip (often labeled as RC-302 or associated with MosChip) is used to add IEEE 1284 parallel ports to desktop computers.
