MD-3
Functional Considerations
The Light Viper MD-3 is very simple device designed to translate RS-232, RS-422 and MIDI data into TTL
control data, thereby allowing it to be transported via fiber through the “control circuit” connectors that
appear on the LightViper VIS-1832, VIS-4832, VIM-1832, VIM-1032, VIM-1808 and VIM-0808. The MD-3
is designed to be used in pairs. A single MD-3 contains (1) RS-232 connector, (1) RS-422 connector, and
(1) MIDI connector located on the front of the MD-3. On the back of the unit there are (3) corresponding
RJ-45 connectors, and a switch to determine MIDI send/receive status.
Standard Components
In its standard configuration, the Light Viper MD-3 data translation and transport system consists of three
primary components:
2 ea. Of the MD-3 - This is the hardware interface. One unit is placed on each end of the data
connection.
RS-422, 232 or MIDI input / output cables – These cables connect the devices transmitting the control
signals into the MD-3 on the “send” side of the data path, as well as connecting the data output from the
MD-3 to the devices on the receiving end of the data path.
CAT-5 jumpers – one CAT-5 jumper cable at each end is required for each of the data protocols being
translated (RS-422, RS-232 or MIDI). These connect the RJ-45 connectors on the MD-3’s to the
LightViper “Control Circuits” connectors on both the send and receive end of the data path.
Getting Started
Setting up and using your Light Viper MD-3’s is quick and simple. Just follow these steps:
1. Mount (1) MD-3 close to the VIM-1832, VIM-1032 or VIM-1808 (“send” or mixer end)
2. Mount (1) MD-3 close to the VIS-1832, VIS-4832 or VIM-0808 (“receive” or stage end).
3. Connect the MD-3’s using standard DB9 (RS-422 or RS-232) control cables, or MIDI control
cables, on both send and receive ends of the data path.
4. Connect the MD-3’s to the LightViper “Control Circuit” RJ-45 connector on both ends of the data
path using CAT-5 jumper cables.
5. If using MIDI control, set the MIDI switch on the data origination end to “send”, and set the MIDI
switch on the data receive end to “receive”.

MD-3 Front Panel
RS-232 connector – This connector is used to input RS-232
control data at the “send” origination end, and / output RS-232 control
on the “receive” or destination end.
MIDI Connector – This connector is used to input MIDI control
data at the “send” origination end, and output MIDI control data at the
“receive” or destination end.
RS-422 connector – This connector is used to input RS-422
control data at the “Send” origination end and output RS-422 control
data at the “receive” or destination end.
MD-3 Rear Panel
RJ45 connector #1 – Connects the RS-422 output data to the
MD-3 of the LightViper “control circuit” connector on the “send” side of
the chain, and connects the output of the “control circuits” connector
to the MD-3 on the “receive” side of the chain.
RJ-45 connector #2 – Connects the MIDI output data to the MD-
3 of the LightViper “control circuit” connector on the “send” side of the
chain, and connects the output of the “control Circuits” connector to
the MD-3 on the “receive” side of the chain.
MIDI Send / Receive switch - This switch must be set to the
appropriate “send” or “receive” setting as MIDI requires this setting to
correctly send / receive MIDI data.
RJ-45 connector #3 – Connects the RS-232 output data to the
MD-3 of the LightViper “control circuit” connector on the “send” side of
the chain, and connects the output of the “control circuits” connector
to the MD-3 on the “receive” side of the chain.
