Introduction
Congratulations on your purchase of a LightViper system. LightViper products are designed, engineered and manufactured by
FiberPlex Inc., experts in fiber optics with decades of experience. Our work in audio and data communications products is
known in US government applications worldwide. LightViper products combine our pioneering technology with the highest
standards in audio engineering.
The LightViper System
You have purchased the LightViper DMX4. Instead of traditional heavy multi‐conductor copper cable,
LightViper fiber optic systems utilize lightweight, flexible, military tactical grade fiber‐optic cable or
duplex PVC and plenum rated fiber for installation use. The DMX4i and DMX4o units allow you send
(4) universes of DMX lighting control through your LightViper snake system (FOH to Stage only) via
the same fiber‐optic cable that carries your (8) audio returns.
The Fiber Advantage
 Fiber optics offer many advantages over copper:
 Transmits light rather than electrons
 Transmission over greater distances (more than 2 Km [1.25 mile])
 Complete electrical isolation
 Immunity to RFI and EMI
 Eliminates ground loop problems
 Can be routed overhead, through walls, or underground
 Avoids foot traffic while maintaining aesthetics
Functional Considerations
The Light Viper DMX4 is an accessory item intended for use with any LightViper 1832, 4832 or 1808 system. These units will
only work when properly connected to an existing LightViper fiber‐optic system. The LightViper DMX4 units contain no user
serviceable parts. Please contact Fiberplex directly with any service issues.
Standard Components
DMX4i — The DMX4i contains (4) 3‐pin female XLR connectors (inputs), (4) 5‐pin female XLR connectors (inputs), a single
female DB9 connector (inputs), and a single RJ45 EtherCon™ connector. All DMX control inputs are connected to this unit.
DMX4o – The DMX4o contains (4) 3‐pin male XLR connectors (outputs), (4) 5‐pin male XLR connectors (outputs), a single male
DB9 connector (output), and a single RJ45 EtherCon™ connector. All DMX control inputs are connected to this unit.
DMX interface cables – DMX cables are required to input DMX control into the DMX4i and output DMX control from the
DMX4o. These cables are not supplied with the DMX4 units and can be purchased separately from your local lighting or music
retailer. The DMX4i and DMX4o can use either (3) pin or (5) pin DMX cables. This system offers ONE WAY control only – from
FOH to stage.
CAT5 Jumpers – CAT5 jumpers are required to connect the DMX4i and DMX4o to the LightViper transport system. These
jumpers are not supplied with the DMX4 units. We recommend “Ruggedized” CAT5 connectors be used in situations where
these cables may be prone to being stepped on or pulled while in use.
