Description
The Black Box MED100A is an asynchronous serial extender that enables long-distance communication of RS232, RS422, and RS485 signals over multimode fiber optic cable. The extender supports distances up to 4 kilometers (2.5 miles) using two ST multimode fibers, making it ideal for industrial applications requiring serial communication across large facilities. The unit features three-way isolation to protect against ground loops and electrical interference, ensuring reliable data transmission in electrically noisy environments. Indicator LEDs provide clear status monitoring of power, signal, and link activity. The MED100A is suitable for point-to-point or ring topology configurations and is ideal for factory automation, security systems, remote monitoring, and any application requiring reliable long-distance serial communication.
