Black Box MD940A Async RS232 Extender over Fiber

Black Box MD940A Fiber Driver

This Black Box MD940A Fiber Driver converts standard RS-232 signals into fiber optic signals, which can then be transmitted over several kilometers depending on cable type and power setting. This device supports asynchronous, bi-directional RS-232 data transmission. It is switch selectable for either DTE or DCE applications, eliminating the need for special cables and preventing confusion during installation.
