rev A Trango Systems, Inc. 3The MTX-2500™Wireless Video/Audio TransmitterCongratulations on choosing the MTX-2500 video/audio transmitterfrom Trango Systems. When unpacking the unit, verify that the follow-ing items are present:•MTX-2500 transmitter•attached omnidirectional antenna•combination input cable with connectors for power (nine-volt battery)and audio (RCA)If any items are missing, notify your sales representative. If an itemappears to be damaged from shipment, replace it in its packing mate-rial and notify the shipper.Important! Intentional or unintentional changes or modifications tothis transmitter not expressly approved by the party responsible forcompliance, must not be made. Any such modifications could void theuser’s authority to operate the equipment and will void the manufac-turer’s warranty.System DescriptionThe MTX-2500 is a miniature wireless video/audio transmitter designedfor transmitting composite NTSC or PAL video and audio signals simul-taneously using 2.4GHz wireless technology.The system is ideal for short range transmission where small size, mo-bility, and low current consumption are required. Due to the nature ofradio frequency (RF) transmission characteristics, the unit will performbest while stationary, and not moving. A moving transmitter will causenoticeable intermittent interference at the receiver, and this is normal.
4MTX-2500 Operating InstructionsSetup Guide1Prior to connecting the MTX-2500, verify proper operation of videosource and monitor/video recorder using a directly connected cable.2Connect the power/audio cable to the MTX-2500 and attach a nine-volt battery. Note: the unit will operate between 6 and 13.8 voltsDC, if you desire to use a different power source.3Connect the video and audio sources to the RCA inputs as shown.!Audio input. Designed to mate to a standard male RCA connec-tor, the audio input jack accepts 1Vpp audio input and is terminatedwith 47KΩ line configuration. A preamplifier must be used to con-nect a microphone to this input."Video input. Designed to mate to a standard male RCA connec-tor, this input accepts 1Vpp video in both NTSC and PAL formats.This input is terminated with 75Ω. RCA-to-BNC adapters are avail-able for use with some cameras and VCRs.#Power. Nine-volt battery connector. Alternatively, a voltage be-tween 6 and 13.8 volts DC may be applied. The nominal current drawis 95 milliamperes. For alternative battery sources, the user may clipthe supplied battery lead; special care must be used to ensure thatVIDEOCAMERAor CAMCORDERMONITORCABLEVIDEOCAMERAor CAMCORDER9VDCAUDIOVIDEOMTX2500-MPON1 2

This switch controls the transmitter chan-nel. Remember to change the receiver (either Eagle PLUS™ or Sting-ray™) channel as well, since it is not automatically changed whenthe transmitter channel is changed.4Move and adjust the orientation of the MTX-2500 and receiver un-til the best picture is obtained. The best picture will be obtainedwhen orienting the MTX-2500 within the receiver antenna beamwidth, unobstructed, as shown.Receiver OperationSee your Stingray or Eagle PLUS documentation for proper use of videoreceivers from Trango Systems, Inc.Operational HintsThe MTX-2500 is factory-configured for operation on channel 1. Thestandard transmitter is supplied with an omnidirectional (or 360°) an-tenna that allows the receiver to be located in any direction relative tothe transmitter within a 45° beamwidth vertically. To obtain the bestpicture quality and transmission distance, the following rules of thumbshould be followed:•Place the transmitter and receiver antennas above human and me-chanical traffic but away from metallic objects.•Keep the transmission path as open as possible. Objects such aswalls, ceilings, and metallic objects near the transmission path canreflect signals and may reduce the transmission distance.60° 45°
6MTX-2500 Operating Instructions•If operating more than one system in an area, set the channels as farapart as possible on each system (i.e. system A uses channel 1, sys-tem B uses channel 4).Transmission RangeThe system is designed to operate up to three hundred feet in mostoffice environments, and two thousand feet line-of-sight. Buildings withthick steel-reinforced or concrete inner walls will reduce the maximumobtainable range.ServiceIf the unit ever needs repair service, contact your Trango Systems, Inc.,dealer for return authorization and shipping instructions.FCC InformationThis equipment has been tested and found to comply with the limitsfor a Class B digital device, pursuant to Part 15 of the FCC Rules. Theselimits are designed to provide reasonable protection against harmfulinterference in a residential installation. This equipment generates,uses, and can radiate radio frequency energy and, if not installed andused in accordance with these instructions, may cause harmful inter-ference to radio communications. However, there is no guarantee thatinterference will not occur in a particular installation.If this equipment does cause harmful interference to radio or televi-sion reception, which can be determined by turning the equipment offand on, the user is encouraged to correct the interference by one ofmore of the following measures:•Reorient the receiving antenna.•Increase the separation between the affected equipment and the re-ceiver.•Connect the affected equipment to an outlet on a different circuitfrom that which the receiver is connected to.•Consult the dealer and/or experienced radio/TV technician for help.
rev A Trango Systems, Inc. 7TroubleshootingInterference. If interference such as lines in the pictures are observed,changing the channels may cure the problem. Also, AC generators inclose proximity to the transmitter or receiver may cause lines in thepicture. Move the unit away from the source of the interference. Note:microwave ovens may interfere with this product.No Picture. Check that the transmit and receive channels are set thesame. Verify all connectors are tight.Poor Picture Quality. Raise transmitter and receiver antennas aboveground and away from obstacles and traffic, including foot traffic.Video Too Dark. Make sure that any monitors and other peripheralequipment connected to the video source are set to high impedance ter-mination since the MTX-2500 transmitter has a built-in 75Ω termina-tion.Video Too Bright. Make sure that the receiver video output line isterminated with 75Ω.Please contact our Technical Support staff at 1-858-653-3900.SpecificationsRadio SectionFrequencies:Channel 1: 2413 MHzChannel 2: 2432 MHzChannel 3: 2451 MHzChannel 4: 2470 MHzRF Output Power: 9dBm ± 1dB EIRP withomni antenna.
