TYPICAL KIT Adapter RCA (F) to RCA (F) 2W-5W Video Transmitter with Heatsink 4 Included with your 5 Watt -2 Watt Transmitter: Screwdriver Programming Cable with Power Adapter Antenna (ANT-VIX) Cable for Camera Power 2.
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.
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.
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.
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.
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.

PROGRAMMING Introduction DTC has built in a lot of flexibility in the programming options you have on the VMS series transmitters. 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.

FEATURES The VMS transmitters are small module transmitters designed for off-body applications. 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.
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.
