1. 3 Each Stinger 5 8 ships with a custom single band 5 8 GHz whip antenna marked with a yellow ring near the base Caution Never operate this transmitter without an antenna rated for 5 8GHz or damage may occur Donot mistakenly use 2 4Ghz antennas with this transmitter Other antennas may look the same but they are not the same inside Donotremove the yellow ring because you will then be unable to tell the 5 8Ghz antennas from other antennas Ask us how we know e Do not use other antennas even if they claim to be 5 8GHz unless you are sure that they 10 are not dual band Dual band antennas do not perform well Stinger Pro 5 8 transmits 2 FM side channels one for direct microphone use the other for line level audio or medium speed serial data Exclusive ultra sensitive AUtomatic Level Controlled ALC microphone amplifier on the microphone audio channel To save weight and space the audio inputs use solder pads that the user can solder to if they wish The user must unsolder and remove the shorting resistor that is placed across the pads by the factory before using the input This is easily done A lectret microphone like most computer mics can be used or an even a bare lectret microphone cartridge can be directly wired in The sensitivity is unbelievable yet the mic will not saturate or clip with even the loudest sounds On board switching power supply means very high efficiency and wide input voltage capability2. 4 MANUAL STP5 8 Tf oF l gl Dec 14 2008 Rev B Techcom STINGER PRO 5 8 STP5 8 5 8GHz 24dBm Video Audio Data Transmitter USER MANUAL Introduction The Stinger Pro 5 8 is an extremely compact microwave AV transmitter operating in the 5 8GHz frequency ISM band Designed specifically to avoid interference from 2 4GHz radio sources such as WiFi remote controls and other similar emissions the Stinger Pro 5 8 broadcasts NTSC or PAL SECAM video plus two microphone and line level audio data channels The Stinger Pro 5 8 features a highly efficient on board switching power supply for both the transmitter and our plug in Universal Camera Power Supply UCPS as well as an exclusive battery saver Stinger Pro 5 8 delivers ultra wide video bandwidth for unrivaled video quality when paired with Iftron YellowJacket Pro 5 8 Diversity or Nano 5 8 Modular ultra wide band video receivers S KJ ey s ry bal Aa bn Nd vd al te HE Considerable development has gone into the design of the Stinger 5 8 Pro Please read this manual thoroughly so that you may better understand the features and operation Notice This transmitter must be operated in accordance with applicable regulations Features and Information 1 7 channels from 5 740 to 5 860 GHz 20 MHz channel spacing 2 250mw 24dBm 1dBm of certified output power We certify each transmitter during test to insure that the output power meets our standards
3. The Stinger Pro runs on 6 volts to 15 volts with equal efficiency Exclusive power pilot LED resolves the question of whether the transmitter is getting power and is on The LED is on only when the switching power supply is functioning This means that the LED is only on when the unit is properly powered and the input voltage meets the minimum voltage requirement as set by the battery saver selection switch See 10 below Reverse input voltage protected Exclusive 2 and 3 cell lipo battery saver The dip switch should be set to 2 or 3 lipo cells When the battery gets extremely low the transmitter will stop transmitting and also shuts down power that goes out to the UCPS Universal Camera Power Supply if one is in use Please note that when the battery saver is active there is still some small power drain so the user must still disconnect the battery to avoid eventual battery damage Input power and video is via our included 6 pin wired connector If you have purchased our optional UCPS this also ships with a compatible 6 pin connector that picks up power for the camera right from the transmitter and passes video back in Exclusive built in cooling fin These transmitters are heat sensitive and should not be wrapped in foam The design includes an exclusive integral cooling fin that facilitates cooling Airflow can greatly enhance performance We encourage mounting the Stinger by a bracket that uses the SMA antenna conn

6. mitter will shut down when the battery is nearly empty If you are using our Universal Camera Power Supply UCPS the battery saver will also shut down the camera power The on board LED will also turn off as an indication Please note that some small current will continue to flow when the battery gets too low Thus the battery should be disconneted to prevent over discharge Note To inhibit operation of the battery saver set the slide switch to 2 cells and use a 3 cell battery Specifications Size W38 x H43 5 x T mm Exclusive of connectors Weight 15 3g Input Voltage 6 15VDC Via input connector Input Power 1 8W at any input voltage On board switching supply Video Input Level 1VP P 75ohms Via input connector Audio Ch1 Input Level User condenser microphone Via solder pads Audio Amplifier Auto Level ALC hi dynamic Audio Data Ch2 Input Level Line 3V RMS 10dcBv typ Via solder pads Capable of audio or medium speed serial data Output Frequencies 5 740 5 860 GHz Channels 7 channels 2OMHz spacing Via dip switch Output Power 24dBm 250mw 1dBm 500hms Caution Install antenna before powering on or damage may occur Antenna SMA 50 ohm connector lftron available antennas here Battery Saver Can be set to 2 3 lipo cells Via dip switch Iftron Technologies Inc reserves the right to make changes in product specifi
7. s bare lectret microphone cartridges are available from most electronics distributors and dealers One example among many example lectret microphone Stinger Pro 5 8 employs a highly sensitive ALC automatic Level Control microphone amplifier on board Amazingly while capable of picking up a whisper at great distance the amplifier will not overload even if you scream directly into it For line level audio or data input use the lower pads marked line See specifications later in this document for more information Mounting and Cooling Stinger Pro 5 8 employs an exclusive integral cooling fin to aid in removal of excess heat Buildup of excess heat will reduce the performance of this transmitter thus we recommend that the transmitter not be wrapped in foam or otherwise insulated Best performance can be achieved when mounted with a bracket using the SMA and included hardware as the mounting point in a manner that allows moving air to reach the Stinger Placement of the antenna is also important to best performance Place the antenna such that no structures block the antenna from the receiving antenna This is especially important if potential obstructions are made of metal or carbon fiber Battery Saver Operation Stinger Pro 5 8 features an exclusive battery saver that helps prevent over discharge of lipo batteries The on board slide switch sets the saver to either 2 or 3 lipo cell operation When properly set the trans
