The MD-3 is a multiple control interface device for translating RS-422, RS-232 and MIDI control signals through LightViper fiber optic transport systems. The MD-3 has (3) three connectors on its front panel: RS-422, MIDI, and RS-232. The rear panel contains (3) three RJ45 connectors and a single switch. The switch is used to determine whether MIDI is sending or receiving on each device. The MD-3 derives power from the LightViper system via the connection between the RJ-45 “control” connector on the LightViper unit and the RJ-45 connector on the MD-3.

The MD-3 is used in pairs; one MD-3 is required at each end of the system. This control data travels with the audio data on the same fiber pair.
