For optimum performance the unitsshould be mounted at a height of 6-7 feet above the ground and no more than 300 feet apart.4• Connect the video audio and alarm inputs and outputs, following the color sche mes onthe cables and connectors.5• Plug the AC adapters into the wall outlet. The LED on the unit should come on and blinkseveral times. The number of blinks indicates the channel. Both units must be on the samechannel for proper operation.6• Adjust the units until the best picture is obtained. Normally this will occur when theunits are oriented as shown below, but in some cases the best picture may occur when theunits are not aimed directly at each other.7• After the picture has been optimized tighten the bracket down using the knob on the sideof the bracket as shown below.

If any items are missing, notify your sales representative. If an itemappears to be damaged from shipment, replace it in its packing material and notify the shipper.Save the packaging for further storage of the equipment.Service:If the unit ever needs repair service, contact your Trango Systems, Inc. distributor forreturn authorization and shipping instructions.FCC Information:Note: This equipment has been tested and found to comply with the limits for a Class Bdigital device, pursuant to Part 15 of the FCC Rules. These limits are designed toprovide reasonable protection against harmful interference in a residential installation.This equipment generates, uses, and can radiate radio frequency energy, and if notinstalled and used in accordance with these instructions, may cause harmful interferenceto radio communications. However, there is no guarantee that interference will notoccur in a particular installation. If this equipment does cause harmful interference toradio or television reception, which can be determined by turning the equipment off andon, the user is encouraged to correct the interference by one of more of the followingmeasures:1) Reorient the receiving antenna;2) Increase the separation between the affected equipment and the receiver;3) Connect the affected equipment to an outlet on a different circuit from that which the receiver is connected to;4) Consult the dealer and/or experienced radio/TV technician for help.VST2500: # NCYVST2500CANADA: XXTBDXXXIMPORTANT NOTE:Intentional or unintentional changes or modifications not expressly approved by theparty responsible for compliance must not be made. Any such modifications could voidthe user’s authority to operate the equipment and will void the manufacturer’swarranty.System Description:The STINGRAY Wireless Video System is a professional quality system designed forsending composite NTSC or PAL video, audio, and alarm signals using 2.4 GHz wirelesstechnology. The system consists of a VST2500 transmitter, VSR2500 Receiver, andpower adapters. The system is ideal for permanent or temporary video links due to itsportable nature and easy installation. It is not designed for operation while in motion.It is not designed for outdoor operation
Copyright © 1999 Trango Systems, Inc. All rights reserved. 3Installation Hints:The STINGRAY system is factory-configured for operation on channel 1 with right andleft audio operational. The system has a very directional transmission pattern thatincreases the transmission range while rejecting interference. If installed properly, thesystem will provide superior picture quality, even when transmitting through walls in atypical home or office setup.To obtain the best picture quality and transmission distance, the following rules of thumbshould be followed:1) Mount the transmitter and receiver antennas above human and mechanical trafficbut away from metallic objects.2) Keep the transmission path as open as possible. Objects such as walls, ceilingsand metallic objects near the transmission path can reflect signals and may reduce thetransmission distance.3) If operating more than one system in an area, set the channels as far apart aspossible on each system (i.e. system 1 use channel 1, system 2 use channel 4).

POWER INPUTAccepts a 6-12 Vdc power source such as the standard 7 Vdc adapter (Trango partnumber PT07800-1), or an optional battery. The nominal current draw is 145milliamperes. If using an adapter from a third party, use a well-regulated 200 mAminimum output supply. Do not use the PT07800-1 to power a camera or videodistortion may occur.2. ALARM INPUTSThese inputs are used to send alarm signals to the receiver. They sense an open orclosed state and reflect that state to the receiver whenever it changes. The alarminputs operate independently of each other. The transmitter is capable of sendingeither alarms or stereo audio, selectable via the Stereo/Alarm switch.3/4. RIGHT & LEFT AUDIO INPUTSDesigned to mate to standard RCA connectors, each input accepts 1 Vpp audio inputand is terminated with 600Ω unbalanced configuration. It is designed to interface to“lineout” audio sources. A preamplifier must be used to connect a microphone to thisinput.5. STEREO/ALARM SWITCHWhen this switch is in the “R Audio Active” position, stereo audio transmission isenabled. This permits the transmission of stereo audio with no alarms. When it is inthe “Alms Active” position, R audio is disabled. In its place, the alarms aretransmitted. The left audio(mono) is always active.6. VIDEO INPUTDesigned to mate to a standard RCA-F connector, this input accepts 1Vpp video inboth NTSC and PAL formats. This input is terminated with 75Ω. RCA-BNCadapters are available for use with some cameras and VCRs.7. CHANNEL DIP SWITCH/ STATUS LEDThis switch controls the transmitter channel. Remember to change the receiverchannel as well, since it is not automatically changed when the transmitter channel ischanged. The status LED will blink to indicate the channel number after the switchis changed.CAUTIONCAUTIONCAUTIONCAUTIONDO NOT APPLY EXTERNAL VOLTAGES TO THE ALARM INPUTS ASPERMANENT DAMAGE TO THE UNIT MAY RESULT. USE ONLY DRYCONTACTS WITH THESE INPUTS.

POWER INPUTAccepts a 6-12 Vdc power source such as the standard 7 Vdc adapter (Trango partnumber PT07800-1), or an optional battery. The nominal current draw is 400milliamperes. If using an adapter from a third party, use a well-regulated 6-12Vdc/500mA output supply.2. ALARM OUTPUTSThese are dry contact relay outputs which can sink 1 ampere at 40 V AC/DC. Whenthe corresponding transmitter alarm input closes or opens, this output will close andopen as well. Consider these outputs mirrors of the transmitter alarm inputs. Theseoutputs are independent and can be used to turn on peripheral devices such as videorecorders and audible alarms.3/4. RIGHT & LEFT AUDIO OUTPUTSDesigned to mate to a standard RCA male connector, this provides a 1.5 Volt peak-to-peak audio output and should be terminated in a minimum 600 Ω load, as is foundin most “line in” audio inputs.5. STEREO/ALARM SWITCHWhen this switch is in the “R Audio Active” position, stereo audio transmission isenabled. This permits the transmission of stereo audio with no alarms. When it is inthe “Alms Active” position, alarm transmission is enabled. Left audio reception isalways enabled.7. VIDEO OUTPUTDesigned to mate to a standard RCA male connector, this provides a 1 Volt peak-to-peak video signal output. This must be terminated with 75 Ω. RCA to BNC adaptersare available for use with some monitors and VCR inputs.8. CHANNEL DIP SWITCH/ STATUS LEDThis switch controls the receiver channel. Remember to change the transmitterchannel as well, since it is not automatically changed when the receiver channel ischanged. The status LED will blink to indicate the channel number after the switchis changed..CAUTIONCAUTIONCAUTIONCAUTIONDO NOT APPLY EXTERNAL VOLTAGES TO THE ALARM OUTPUTS.PERMANENT DAMAGE TO THE UNIT MAY RESULT.

Move the unit away from the source of the interference.NO PICTURECheck that the transmit and receive channels are set the same, and make sure theLED is glowing.Verify all connectors are tight.POOR PICTURE QUALITYRaise transmitter and receiver antennas above ground and away from obstacles andtraffic, including foot traffic.VIDEO TOO DARKMake sure that any monitors/peripheral equipment connected to the video source areset to high impedance termination since the VTX2500 has a built-in 75 Ωtermination.VIDEO TOO BRIGHTMake sure that the receiver video output line is terminated with 75 Ω.Check the Technical Support section of our website at http://www.trangosys.com/ foradditional assistance.
