This is essential in industrial environments where equipment may be connected across different electrical grounds or subject to electrical noise from motors, power supplies, and RF equipment.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eCan this RS-232\/422\/485 card work with legacy industrial equipment?\u003c\/h3\u003e\n\u003cp\u003eYes. The Black Box 2-port PCI card supports all three serial protocols (RS-232, RS-422, and RS-485), making it compatible with virtually all legacy industrial devices, PLCs, sensors, and data acquisition systems.
