FiberPlex’s new MD-3, a multi-control interface translator for its LightViper™ fiber-optic audio systems. translates RS-422, RS-232 and MIDI control signals. The MD-3 has three connectors on its front panel: RS-422, MIDI and RS-232; the rear panel contains 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.
An MD-3 pair is capable of sending a specific type of control signal (e.g. RS-422) through a LightViper system and outputting that same control signal on the opposite end. An MD-3 pair is also capable of outputting a completely different control signal (e.g., MIDI) at the opposite end (translated control output).
The MD-3 is packaged in a compact, rugged steel enclosure. The MD-3 has four rubber feet and a Velcro strip to attach it to an equipment rack. The price for one pair of MD-3 devices is $428.
