FCC ID# H25VMS5000 TYPICAL KIT Adapter RCA (F) to RCA (F) 2W-5W Video Transmitter with Heatsink Included with your 5 Watt -2 Watt Transmitter: Screwdriver Programming Cable with Power Adapter Antenna (ANT-VIX) Cable for Camera Power 2.1mm to Molex Multi I/O Cable for Transmitter Power, Camera Power and Video • • VMS-5000 Video Transmitter packaged in case with heatsink attached Accessories kit containing: • DTC programming software package • DTC programming cable • Camera Cable • Dipole antenna with right angle SMA connector • Video and Power In “Y” cable • Four captive mounting screws • Transmitter mounting bracket (optional) NOTE: DTC has provided you with a “Y” cable (power and video) terminated with an RCA connector and a BNC adapter for your convenience. AC 100-240V Power Adapter with Molex Connector NOTE: The dipole antenna included is not recommended for normal use! This antenna enables you to quickly set up your transmitter and ensure proper operation. DTC highly recommends the use of circularly polarized antennas for the best rejection of multi-path. QUICK START 1 Make sure that the external power source to the transmitter is OFF. 2 Using a screwdriver, turn the channel selector to the correct channel number. 3 Connect an antenna to the ANTENNA connector on the module. 4 Select Hi or Lo Power using the recessed switch. 5 Connect the microphone or microphones to the MIC-1 and MIC-2 connectors on the module. 6 Connect a video source and external power (11 -16 VDC) to the Video/Multi-I/O connector. 7 If you are using an (optional) Encryption model, choose Encrypted (SCR) or Clear (CLR) as desired 8 Apply power to the transmitter. Warning: Do not apply power to the transmitter until an antenna has been connected in step 3. ENCRYPTION OPTION As an option, the transmitter can be equipped with an encryption module with a two position switch. In the CLR (clear) mode, clear analog microwave video is transmitted. In the SCR (scrambled) mode, the video will be scrambled and capable of being decoded by a compatible receiver only. 1.184 Top View Note: The scrambled transmission mode is recommended. Casual scanners will not be able to decode the signal and see what is being transmitted. CLR SCR SCRAMBLER Screws Screws Side View Heatsink, Transmitter, and Encryption Heatsink Transmitter Encryption .33 SCR position = ON, CLR position is OFF HEAT CONSIDERATIONS NOTE: NEVER remove the heatsink. BEST: Fins Vertical Away From Wall Fins Vertical Away From Wall Fins Vertical Against Wall NOTE: HOT SURFACE MAY CAUSE BURNS. Ensure that transmitter is properly ventilated and allow to cool before touching. Heat is an enemy of electronic components so it is imperative that the transmitter is not allowed to exceed 80 degrees C. With the heatsink removed, the temperature would rise to 125 degrees C or more, which would be destructive to the internal components. At 125 degrees C, the unit would also deliver a serious burn if touched. Much of the heat is given off by the final output transistor, which is the most critical component when it comes to heat considerations. The heatsink is shipped mounted to the transmitter with four 6-32 screws, and has two additional 440 screws attached from the fin side of the heatsink to the transmitter around the final output transistor. These screws are critical for thermal conduction from the transmitter to the heatsink. Removing these screws is not recommended. Wall GOOD: Fins Up NEVER: Fins Horizontal Fins Down If you plan to mount the transmitter, be sure to orient the heatsink fins vertically for effective heat dissipation. Use one of the recommended mounting procedures presented on the next page. MOUNTING OPTIONS NOTE: ALWAYS mount the transmitter with the heatsink fins oriented vertically for proper heat dissipation. NOTE: Leave room for the antenna and/or connectors when selecting a mounting surface. The supplied antenna requires more than 5-inches of space. Option One The transmitter and heat sink can be mounted (with cooling fins vertical) against a heat-conductive metal surface. The transmitter ships with four additional 6-32 pan head Phillips mounting screws. • Remove the four 6-32 Phillips screws from the front of the transmitter. • Install the four long 6-32 Phillips screws supplied. The screws become captive. • Pass the screws through the mounting surface and install nuts to secure the assembly. Option Two An optional wall-mount bracket is available from DTC Communications, which will allow simple mounting on a variety of surfaces and enclosures. • Loosen the four 6-32 Phillips screws from the front of the transmitter. • Install the bracket in the orientation shown. Retighten the four Phillips screws. Hang bracket on wall using #10 screws. Option 1 Mounting Scheme 2.420 1.475 1.125 Option 2 Mounting Scheme NOTE: The transmitter’s baseplate operating temperature is -30° to + 80°C. The heatsink is always required. Removing the heatsink is not recommended as excessive heat can destroy the device REINSTALLING HEATSINK The transmitter is shipped with the heatsink attached. Removing the heatsink is not recommended. If, due to your 2.56 particular situation, you find that you need to reinstall the heatsink, refer to the steps provided here. To re-install the heatsink: 1 Ensure the chassis and heatsink surfaces are clean. If needed, use rubbing alcohol to clean, then dry. 3.340 2 Align the transmitter and heatsink, with the back of the transmitter mating with the front, flat surface of the heatsink. 3 Secure the heatsink with four (4) 6-32 x 1” screws (1-1/2” screws if using encryption model). Install the screws from the transmitter side. 4 Make sure there is good contact between the transmitter and the heat sink. They should be mounted flush to one 1.865 another. 5 IMPORTANT Two 4-40 screws must be installed on the outside (fin side) of the heatsink to tighten the heatconductive surfaces nearest the final output power transistor. These screws are essential for proper heat dissipation. Do not operate the transmitter with these screws removed. Screw must not exceed 0.125 depth into transmitter or it will bottom-out and not provide proper heat-conduction. NOTE: Make sure to install all factory-provided hardware to secure heatsink to transmitter for optimal thermal conduction and heat dissipation. The temperature must never exceed 80 Deg.

Each connector has two contacts and provides power to the microphone as well as connecting the audio signal into the transmitter. The audio sub-carriers are activated by the presence of the microphone. If a microphone is removed, that sub-carrier is removed from the transmit signal. Turning off the unused sub-carrier saves power and improves picture quality. Antenna Connector ANTENNAS WARNING: Refer to Appendix A of this manual for information on the proper use of antennas. 10 A standard SMA connector is used as the antenna connector on both the VMS-5000. Refer to a list of DTC antennas available on page 16. TIP: You may use the VMS series transmitters with other manufacturers antennas. Verify that they are suited for the band you are operating in.

You can choose to use some, all or none of this flexibility. When you order a VMS transmitter, DTC will factory program your frequencies at no additional charge to you. You may want to place a sticker over the rotary switch on the chassis, so users in the field don’t attempt to change frequencies. This is often the best path for state and local agencies with limited frequencies available to 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 subcarriers. This is ideal if you often work with other agencies, or anticipate the equipment being used by a multi-jurisdictional task force. You can program up to ten channel settings per unit. In general, this allows you to program most variations you might encounter in the field at the depot level. As a practical matter, your VMS transmitter’s video frequencies and audio subcarriers 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 few channel options. TIP: Make sure that you program your transmitter to match the frequencies and audio sub-carriers on your receiver, and test the components as a system prior to going into the field! 17 PROGRAMMING Installing DTC Universal Programming Software on your PC NOTE: Uninstall any previous versions by going to Add/Remove Programs, clicking on DTC Universal Programming, and clicking on uninstall. 10 11 Click on Start, click on run.

They are part of a family of video transmitters from DTC that provide 250 mW, 2 Watts and 5 Watts output power. Feature Description Programmable User programmable video channels, selectable in 250 kHz steps. Two user programmable audio sub carriers, selectable in 10 kHz steps from 6 MHz to 7.5 MHz. Audio Sub-Carriers Audio sub carriers are OFF unless microphones are connected. The transmitter automatically senses when a microphone has been connected. The audio sub carriers are phase locked, and will not drift into the video signal. Automatic Gain Control is provided on each audio input, amplifying soft sounds. Efficient Switching Power Supply They generate far less heat than traditional video transmitters. They operate significantly longer than traditional video transmitters on the same power source. External Power Loop Through The power applied to the Multi I/O pin is automatically looped through the unit, and available on a second pin to power a remote device, such as a camera. If you apply 12 Volts in, you will get 12 Volts out, with a maximum current drain of 200mA Encryption Options The VMS series supports Ovation Micro ViewLock II™encryption, which adds approximately 0.35” to the thickness of the unit. 24 Appendix A Antenna Safety Using Antennas with the VMS-5000 Video Transmitter Use an antenna suitable for 5-Watt operation, however to ensure safe operation, it is imperative that proper spacing be maintained between the radiating surface of the antenna and any persons body. All RF category “Mobile” equipment must by law use a separation distance of 20 cm. The antenna supplied should not be placed closer than 20 cm (8in) to the body. To ensure that proper spacing is maintained, locate the transmitter or arrange physical barriers in such a way that people are prevented from approaching too closely. Limit your exposure to the antenna when the unit is in operation. 25 486 Amherst Street • Nashua, New Hampshire 03063 • 603-880- 4411 www.dtccom.com
