Copyright © 1999 Trango Systems, Inc. All rights reserved. 5Installation:The EAGLE PLUS system is factory-configured for operation on channel 1 with alarmsoperational and mono audio.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 traffic,the higher the better. A 10 foot steel mast on top of a building is typical. Make surethat the mast is well grounded to earth ground with an 8 AWG or larger wire. Formaximum range, the transmit and receive antennas must be 15 to 20 feet above allobstacles in the line of sight.2) Keep the transmission path as open as possible. Objects such as walls andmetallic objects near the transmission path may reduce the transmission distance.3) Do not add additional lengths of cable to connect the receiver to the antenna assignificant losses in signal, and reduced transmission range will occur.4) Keep the cable connecting the antenna to the receiver as short as possible.The EAGLE PLUS transmitter and receiver units come pre-mounted in a NEMA-4Xrated aluminum enclosure which allows mounting of the unit outdoors.

All rights reserved. 72.4GHz Transmitter Inputs & Controls:VIDEO INPUTDesigned to mate to a standard BNC male connector, this input accepts 1 Volt peak-to-peak video in both NTSC and PAL formats. This input is terminated with 75 Ω.RCA to BNC adapters are available for use with some cameras and VCRs.AUDIO INPUTDesigned to mate to a standard RCA male connector, this input accepts 1 Volt peak-to-peak audio input and is terminated with 600 Ω unbalanced configuration. It isdesigned to be interfaced to “lineout” audio sources. A preamplifier must be used toconnect a microphone to this input.DATA INTERFACEWhen connected to a personal computer via the optional CBLDAT-1 interface cable,this input accepts serial commands that control settings in the transmitter notavailable on the front panel. See the Trangolink software program help for moreinformation.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 150milliamperes. 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.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.CAUTIONCAUTIONCAUTIONCAUTIONDO NOT APPLY EXTERNAL VOLTAGES TO THE ALARM INPUTS ASPERMANENT DAMAGE TO THE UNIT MAY RESULT.

Remember to change the receiverchannel as well, since it is not automatically changed when the transmitter channel ischanged. For increased isolation from nearby systems operating on differentchannels and multiple systems transmitting along the same path, the system can beoperated using right hand polarization on channels 1 and 3, and left hand polarizationon channels 2 and 4 (Additional equipment may be required).Standby Mode:This mode of operation does the following:1) Places the transmitter into a low power mode.2) Stops transmitting the RF signal.3) Continues to monitor the alarm inputs that have been armed (Factory default --both inputs are armed).4) Monitors the data port for control signals from the TrangoLink software.While in Standby mode, if an alarm state change occurs, the transmitter will comeout of Standby mode instantly, begin transmitting the video signal, and change thereceiver alarm output state to reflect the changed state on the transmitter. The unitwill not return to standby mode unless the user holds the toggle button down orcommands the unit via Trangolink.ENTERING STANDBY MODETo enter the Standby mode, the user must hold down the Toggle/Standby switch for 2seconds. The status LED will blink once per second for about 1 minute to allow theoperator to leave the area. During this time the alarms will be disarmed. After 1minute, the alarms will be armed, and the active channel LED will then blink at a rateof about once every 2 seconds to indicate that the unit is in Standby mode, andwaiting for an alarm state change to occur.EXITING STANDBY MODETo exit Standby mode, the user must simply depress the Toggle/Standby switchmomentarily. After exiting Standby mode, the active channel LED will be on solidto indicate that the video signal is being transmitted normally. Alarms will still bearmed unless the are turned off via the Trangolink software.LOW BATTERYIf the input voltage drops below 6V, the active channel LED will blink twice persecond. A low battery indication is also sent to the receiver and can be viewed usingthe TrangoLink software or the receiver. No alarm is generated.

This must be terminated with 75 Ω. RCA to BNC adaptersare available for use with some monitors and VCR inputs.AUDIO OUTPUTDesigned to mate to a standard BNC male connector, this provides a 1 Volt peak-to-peak audio output and should be terminated in a 600 Ω load, as is found in most “linein” audio inputs. RCA to BNC adapters are available for use with some monitors andVCR inputs.DATA INTERFACEWhen connected to a personal computer via the optional CBLDAT-1 interface cable,this input accepts serial commands that control settings in the receiver not availablevia the front panel. See the Trangolink software program help for more information.POWER INPUTAccepts a 12 Vdc power source such as the standard 12 Vdc adapter (Trango partnumber PT12500-1), or an optional battery. The nominal current draw is 350milliamperes. If using an adapter from a third party, use a well-regulated12Vdc/500mA output supply.ALARM OUTPUTThis is a relay output which can sink 1 ampere at 40 V AC/DC. When a valid alarmcondition is received from the transmitter, this output will close to ground. Thisoutput can be used to turn on peripheral devices such as video recorders and audiblealarms.ALARM CLEAR INPUTThis input allows the operator to clear an alarm which has been received. This inputis normally open, and will clear the alarm upon closure to ground.CAUTIONCAUTIONCAUTIONCAUTIONDO NOT APPLY EXTERNAL VOLTAGES TO THE ALARM OUTPUT ORALARM CLEAR PINS. PERMANENT DAMAGE TO THE UNIT MAYRESULT.

All rights reserved. 112.4GHz Receiver Operation:Changing Channels:To change channels, simply depress the Toggle/Standby switch momentarily until theLED for the desired channel pattern is lit up. Remember to change the receiverchannel as well, since it is not automatically changed when the transmitter channel ischanged. For best performance, multiple systems transmitting along the same pathshould be operated using horizontal polarization on channels 1 and 3, and verticalpolarization on channels 2 and 4.Alarm Conditions:When the VRX2400 receives an alarm condition from the transmitter, the activechannel LED will begin blinking.If Alarm 1 is activated, then the active channel LED blinks once between pauses.If Alarm 2 is activated, then the active channel LED blinks twice between pauses.If both alarms have been activated, then the active channel LED blinks three timesbetween pauses.The active channel LED will stop blinking when the alarm condition is cleared.RSSI Mode:To ease alignment of the receiver antenna, the received signal strength may beviewed by placing the unit in RSSI mode. The LEDs will then act as a bar-graphindicator, with more LEDs lit for a stronger signal.To enter RSSI mode, hold down the Toggle/RSSI button for 2 seconds. To exit,depress the button momentarily. The number of LEDs lit is a relative indication ofsignal strength to be used only to find the best antenna position. Viewing thereceived picture quality should be used in conjuction with this mode.

All rights reserved.12INTERFERENCEIf interference such as lines in the pictures is observed, changing the transmissionchannel may cure the problem.Also, AC generators in close proximity to the transmitter or receiver may cause linesin the picture. 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 thetransmitter is not in Standby mode (slow, blinking LED), or that the battery is notlow (fast, blinking LED).Verify all connectors are tight.POOR PICTURE QUALITYRaise transmitter and receiver antennas above ground and away from obstacles andtraffic, including foot traffic.Use an optional high-gain dish antenna on the receiver. Verify all connectors aretight. Shorten the receiver antenna feed cable.VIDEO TOO DARKMake sure that any monitors/peripheral equipment connected to the video source areset to high impedance termination since the VTX2400 has a built-in 75 Ωtermination.VIDEO TOO BRIGHTMake sure that the receiver video output line is terminated with 75 Ω.CAN’T COMMUNICATE WITH TRANSMITTER OR RECEIVER USINGTRANGOLINKPerform a system reset by holding toggle switch down while applying power. Allmemory locations will be erased and the system will be reinitialized. All LEDs willlight up to indicate a successful reset. Release the toggle switch.
