  • Page 3: Introduction

    1. Introduction The AeroX Audio105 is an audio controller that allows digital voice files to be transmitted over ground to air radios. Furthermore, it allows users to append audio messages to be transmitted through multiple audio inputs/outputs. Thus, the AeroX Audio105 fulfills the hardware component of an Automatic Terminal Information Service (ATIS) that produces critical flight safety information in the form of an audible voice information stream that can be transmitted over a radio for pilots.

    VU LEDs: Visual indication of selected monitor audio source 6x green LEDs and one red LED to show increasing audio level from lower LED up. For optimal performance the audio level should be high enough to light all the green LEDs but not the red LED, or at most only light the red LED occasionally.

    Initially, the POWER and VU LEDs illuminate. After 5 seconds, the AeroX Audio105 beeps and the LCD displays the Campbell Scientific logo. A solid POWER LED (not flashing) indicates the power-up process is complete and the AeroX Audio105 is fully operational. The final LCD screen should look similar to the following: 6.3 VOL/DATA dial...

  • Page 13: Ptt Microphone

    6.4 PTT microphone The PTT microphone allows the recording of messages directly into the AeroX Audio105. It is plugged into the 3.5 mm jack on the right side of the front panel. To operate, press the microphone button and hold while speaking into the microphone, then release the button when finished recording the message.

  • Page 14: Audio Inputs

    NOTE: The audio only transmits through one side of a stereo headphone. Connecting a headphone with an impedance of less than 300 ohms may cause reduced audio levels out of the XLR channel in which the headphone is connected. Maximum common mode voltage (pins 2 and 3) relative to ground is ±17 V. Ideally audio cables are screened.

  • Page 15: Ptt Connector

    6.7 PTT connector The rear panel includes a 25-pin, D plug that provides five PTT, volt-free, relay contacts that can be independently controlled to activate VHF radio transmitters or other devices. The relay contacts are rated at 50 VAC or DC at 1 A, but are NOT overload protected. Maximum voltage on any contact relative to ground is ±50 VAC or DC.
  • Page 16 An optically-isolated, auxiliary, digital input on this connector can be used with special software (contact factory for support). Maximum common mode voltage for pins 11 and 24 relative to ground is ±15 V. Input pins 11 and 24 are reverse polarity protected and is active if the voltage applied is greater than +3.5 V.

  • Page 17: Lights Connector

    6.8 LIGHTS connector The LIGHTS connector is primarily used to turn on helicopter landing pad lights and is configured as a single, break-before-make, change-over, normally open, normally closed contact. Rated at 50 V at 1 A, this relay contact is NOT overload protected. Maximum voltage on any contact relative to ground is ±50 VAC or DC.

  • Page 18: Redundant Connector

    6.13 Redundant connector A redundant AeroX Audio105 rack module connects to this 9-pin D plug to support fault tolerance. For example: if two AeroX Audio105s are used for a single audio stream, the second box will act as a redundant audio box that can take over the audio if the first box fails or is powered down.

    4. Rotate the Vol/Data dial to select "Restart". 5. Press the Vol/Data dial and confirm. 6. AeroX Audio105 will restart and copy files from the AudioServer\ directory and replace existing files on SBC. NOTE: The AeroX Audio105 update process will not replace files if their versions are the same. Therefore, the USB drive can be left in the USB port without any issues on the next start up.
