Description

Black Box MED102A Async RS232/422/485 Extender Over Fiber - Terminal Block TO Singlemode SC

Overview

The Black Box MED102A provides robust, long-distance serial data extension for industrial and security applications. This fiber optic extender converts asynchronous serial signals (RS232, RS422, or RS485) into a fiber optic transmission, enabling communication up to 2 kilometers over singlemode fiber. It's designed to overcome the distance limitations and electromagnetic interference inherent in copper serial cabling, making it suitable for connecting remote devices like PLCs, industrial sensors, or camera pan-tilt-zoom (PTZ) controllers in harsh environments.

Compatibility

This extender is designed for point-to-point fiber optic extension of standard asynchronous serial protocols. It interfaces with devices that utilize terminal block connections for RS232, RS422, or RS485 signaling. The fiber side uses an SC connector for singlemode fiber, compatible with standard singlemode fiber optic transceivers and patch panels. It is not specific to any particular camera or VMS brand but extends the serial interface of any device supporting these protocols.

Installation Notes

Installation requires a pair of MED102A extenders (one at each end of the fiber run). Ensure the correct serial interface (RS232, RS422, or RS485) is selected via jumpers on both units. Use appropriate terminal block connectors for your serial wiring and an SC-to-SC patch cord for the singlemode fiber connection. Verify fiber optic polarity and signal integrity before commissioning. The operating temperature range is -10°C to 55°C (14°F to 131°F), suitable for controlled indoor or protected outdoor installations.
