Thisantenna enables you to quickly set up your transmitter and ensure properoperation. DTC highly recommends the use of circularly polarized antennasfor the best rejection of multi-path.3546
5OVERVIEWThe VMS transmitters are small module transmitters designed for off body applications. They are part of a family of videotransmitters from DTC that provide 250 mW, 2 Watts and 5 Watts output power.Feature DescriptionProgrammableUser programmable video channels, selectable in 250 kHz steps. Twouser programmable audio sub carriers, selectable in 10 kHz stepsfrom 6 MHz to 7.5 MHz.Audio Sub-CarriersAudio sub carriers are OFF unless microphones are connected. Thetransmitter automatically senses when a microphone has beenconnected.The audio sub carriers are phase locked, and will not drift into thevideo signal.Automatic Gain Control is provided on each audio input, amplifyingsoft sounds.Efficient Switching Power SupplyThey generate far less heat than traditional video transmitters.They operate significantly longer than traditional video transmitters onthe same power source.External Power Loop ThroughThe power applied to the Multi I/O pin is automatically looped throughthe unit, and available on a second pin to power a remote device,such as a camera. If you apply 9 Volts in, you will get 9 Volts out, witha maximum current drain of 200mAEncryption Options The VMSseries supports Ovation Micro ViewLock II™encryption,which adds approximately .35" to the thickness of the unit.

In applicationswhere the baseplate temperature willexceed +80°, add “-HO” to anyVMXX-2000 transmitter part numberfor the optional heat sink at noadditional charge. The drawing onthe left clearly marks the mountingholes for the heatsink installationwhen required. To install theheatsink.1Align the mounting holes of the transmitter to themounting holes on the heatsink.2Secure the heatsink with four (4) 6-32 x 1”screws.
10MICROPHONE CONNECTORSTwo connectors accommodate two microphone inputs. Eachconnector has two contacts and provides power to themicrophone as well as connecting the audio signal into thetransmitter. The audio sub-carriers are activated by thepresence of the microphone. If a microphone is removed,that sub-carrier is removed from the transmit signal. Turningoff the unused sub-carrier saves power and improves picturequality.Microphone ConnectorsCONNECTORSLemo Male Part # (FFS.01.250.DLAE31)DTC Male Part # (8570003)Hirose Part # HR10A-7P-6P (02)DTC Part # 954020MATING CONNECTORSAntenna ConnectorWARNING: Refer to Appendix A ofthis manual for information on theproper use of antennas.Standard Male SMA ConnectorANTENNASA standard SMA connector is used as the antenna connectoron the VMS-2000.

23APPENDIX AUsing Antennas with the VMS-2000 Video TransmitterAny suitable antenna may be used, however to insure safe operation, it isimperative that proper spacing be maintained between the radiating surface ofthe antenna and any persons body. No antenna should be placed closer than 19inches (48 cm) to the body. To insure that proper spacing is maintained, locatethe transmitter or arrange physical barriers in such away that people areprevented from approaching too closely.
24 PROGRAMMINGIntroductionDTC has built in a lot of flexibility in the programming options you have on theVMS series transmitters. You can choose to use some, all or none of thisflexibility.When you order a VMS transmitter, DTC will factory program your frequencies atno additional charge to you. You may want to place a sticker over the rotary switchon the chassis, so users in the field don’t attempt to change frequencies. This isoften the best path for state and local agencies with limited frequencies availableto them.DTC will also provide you with free software and a free programming cable,enabling you to change your video frequencies and their associated audio sub-carriers. This is ideal if you often work with other agencies, or anticipate theequipment being used by a multi-jurisdictional task force. You can program up toten channel settings per unit. In general, this allows you to program most varia-tions you might encounter in the field at the depot level.As a practical matter, your VMS transmitter’s video frequencies and audio sub-carriers will be dictated by the frequency and sub-carriers(s) of your receiver and/or repeater. In many cases, these devices are crystal controlled or have fewchannel options.TIP: Make sure that you program your transmitter to match the frequenciesand audio sub-carriers or your receiver, and test the components as asystem prior to going into the field!
