Important Safety Instructions EN_1
1. Readthese instructions. Keep these instructions. Heed allwarnings. Follow all instructions.
5. Donot use this apparatus near water. Cleanonly with dry cloth.
7. Donot block any ventilation openings. Install in accordance with the manufacturers
instructions.
8. Donot install near any heat sources such as radiators, heatregisters, stoves,or other
apparatus (includingamplifiers) that produce heat.
9. Donot defeat the safety purpose of the polarized or grounding-type plug. A polarized plug
has twoblades withone wider than the other. Agrounding type plug has two blades and a third
grounding prong. The wideblade or the third prong are provided for your safety. Ifthe provided
plug doesnot fitinto your outlet consult an electrician for replacement of the obsolete outlet.
10. Protectthe power cord from being walked on or pinched particularly at plugs,convenience
receptacles, andthe points where they exit from the apparatus.
13. Referall servicingto qualifiedservice personnel. Servicing is required when the apparatus
has beendamaged in any way, suchas power-supply cord or plug is damaged, liquid has been
spilled or objects havefallen into the apparatus,the apparatushas been exposed to rain or
moisture, doesnot operatenormally,or has been dropped.
14. Apparatusshall not be exposed to dripping or splashing and that no objects filled with liquids,
such asvases shall be placed on the apparatus.

NOTE1: Digital video optic transmitterand receivershould be used in pairs, one is Transmitter
(LED is red), theother is Receiver (LED is green).
NOTE2: Avoid simultaneously connecting video signals to both the front BNC and rear BNC of the
same channel.Also, since each video channel is factory terminated to 75 ohm, unused BNCs
should notbe used for loop-through video connections.

Stand-alone Installation En_8
The VOS-4FOM-D422T transmitter/VOS-4FOM-D422R receivercan be mounted into a rackor can be
used as a stand-alonemodule. As a stand-alone module, the unit can be placed on a desktop or
can bemounted toa wall.
NOTE: Before mounting the VOS-4FOM-D422T transmitter/VOS-4FOM-D422R receiver, please
ensure that there is adequate space at both ends forviewing the front-panel LEDsand for making
the variousrear-panel cableconnections.

Rack-mount Installation En_9
Installation Instructions
Typical Configurations:
1:Install the video card into a standard 19inch rack, usinguser-supplied rack-mounting
hardware. Becareful to not damage exposed objects on the back of the card cage unit.
2:If asecondary earth ground connectionis needed, a grounded wire with a ground lug can be
attached to the rackusing the protruding screw provided on the right side of the chassis.
3:If desired, blank panels may beinstalled tocover unused slots. A single blank panel coversa
single slot opening.
4:Each fiber optic plug-in module is equipped with a POWER LED indicator that illuminates
when power is applied to the rack unit.
5:Fiber optic plug-in modules(video cards) can be installed into anyof theavailable 14slots
of thecard cage. Most modules require onlya single slot width, but others, such as the 8-Ch
video Series, require two slot widths.
VOS-CH04:
19 inch4U,14 video card slots, suit for 1-ch,2-ch,4-ch,8-ch(two slots)video cards.
Support oneslide-in power supply AC100V~AC240V
VOS-CH06:
19 inch6U,16 video card slots, suit for 1-ch,2-ch,4-ch,8-ch(two slots)video cards.
Support two slide-in power supply AC100V~AC240V, one for redundancy.
