LightViper Technology Overview
The LightViper Series 32 product line is a straight forward point to point audio transport
system. Systems can be made up in building blocks of 32 x 8 channels transporting either
analog or digital I/O. Incoming signals are multiplexed and transported synchronously
via fi ber optic cable. Multiple fi ber optic transceivers can be driven to provide optically
isolated splits of the transmitted audio. Output options include line level analog, AES3
digital or direct fi ber connection to a Yamaha console via Mini-YGDAI cards. The Series
32 system also provides for transmission of RS-232/422, MIDI, DMX lighting control or
Yamaha HA control along with the audio.
By using a fully synchronous time division multiplex transmission scheme, the
LightViper system minimizes digital to digital transmission latency to a negligible 10 µs.
The biggest advantage, however, comes in the transmission media itself; fi ber optic
cable.
Fiber cable is made from glass silica which is an abundantly available resource,
meaning that it's friendly for the environment. Functionally, fi ber by nature is nonconductive.
This means it provides complete end to end electrical isolation eliminating
common problems such as ground loops. It is impervious to external interference such
as EMI/RFI and even EMP caused by nearby lightning strikes. Finally, fi ber cable offers
dramatically extended range with multimode connections reaching as far as 2 km and
singlemode as far as 20 km or more.

YamMon software provides complete remote control capability for up to 255
Yamaha AD8HR microphone preamps from a remote PC computer. In addition
to full functional support of the Yamaha communications protocol, YamMon provides the capability to uniquely name each
preamp module as well as each individual channel for complete organization. Your entire confi guration can be easily saved
to a fi le for backup and future recall. A simple RS-232 null modem connection is all that is needed to control an entire bank of
AD8HRs. For a complete fi ber optic remote control setup, feed the digital outputs of the AD8HRs into a LightViper VIS-4832
system and pass the control signal for the preamps right down the same fi ber!

LightViper Interface Card for Yamaha Digital Mixer
VIM-MY32MT4, VIM-MY32MOC, VIM-MY32MLC, VIM-MY32S
LightViper VIM-MY32 MY-cards enable users of Yamaha PM5D, M7CL, DM2000, DM1000 and LS9 consoles to interface with the LightViper
1832 and 4832 systems via direct digital fi ber-optic input to the console. The end result is a neater, more compact transport system with fewer
parts, fewer connections, less headaches and even quicker set-up and tear down times.
The VIM-MY32 cards are available in the following confi gurations:
VIM-MY32MT4
Master card with a single TAC-4 Fiber connector
VIM-MY32MLC
Master card with LC fi ber connectors
VIM-MY32MOC
Master card with a single Neutrik OpticalCon ® fi b e roptic
connector
VIM-MY32S
This slave card is connected to the master card via a
Neutrik jumper cable /connector
The MY-32 cards contain a 24 bit / 48 kHz master clock, and can either send clock to the console and distribute it to the rest of the system
(master), or accept external clock from the console and distribute it to the rest of the system (slave). Master and slave cards are connected via
a supplied 12 pin high speed Neutrik MiniCon ® cable.
RoHS compliant, the LightViper VIM-MY32 cards carry the Fiberplex limited lifetime warranty and are manufactured in the USA.
