Move RS232 communications beyond the limits of copper with a media converter designed for longer-distance serial transport. Black Box RS232 TO MM/SC 2.5KM STANDALONE INTL PS, MPN ME660A-MST-R2, converts RS232 to multimode fiber with SC connectivity and supports reaches up to 2.5 km. This is the right fit when serial devices must remain connected across buildings, plant floors, or distributed equipment rooms without introducing the noise sensitivity and distance constraints of direct copper cabling. The standalone design makes it practical for targeted deployments where a dedicated conversion point is needed rather than a chassis-based architecture. For infrastructure teams, the value is control: preserve legacy serial connectivity while extending the physical footprint of the system. For procurement, the appeal is clear specification alignment — RS232, multimode fiber, SC interface, and a defined 2.5 km reach. That combination reduces guesswork and supports cleaner deployment planning. Choose this Black Box converter when the application depends on stable serial transport, a compact standalone footprint, and a fiber path that keeps critical equipment connected across distance.
