  • Page 9: Introduction

    2. Introduction 2.1 AXP340 Description The AXP340 Mode S panel mount transponder is an ED-73E and DO-181E Class 1 compliant Mode S level 2es datalink transponder, with support for extended squitter, elementary surveillance and SI codes. The AXP340 is also a DO-260B Class B1S compliant ADS-B out participant. The AXP340 meets the relevant environmental requirements of DO-160G/ED-14G, and is certified to ETSO C112d, ETSO C166b, TSO C112d and TSO C166b.

    To justify your claim, save the original shipping container and all packaging materials. 5.2 Mounting The AXP340 Mode S transponder must be mounted rigidly in the aircraft panel. The following installation procedure should be followed, remembering to allow adequate space for installation of cables and connectors.

    *: These signals are different to the KT76A/KT76C/KT78A pinout; on the KT76A, KT76C and KT78A these signals are not usually connected in the aircraft. The following diagram shows the connector orientation as it would be fitted to the mounting tray. AVIDYNE CORPORATION Page 9...

  • Page 17: Secondary Interface - Pinout

    In the example shown the aircraft uses a 14 volt lighting bus, a parallel altitude encoder, a DME with simple suppression output, a GPS with serial position output, and a simple lamp for the altitude alerter. This example is representative of a simple fixed gear 14 volt aircraft. Page 10 AVIDYNE CORPORATION...

  • Page 18: Interface Details

    The AXP340 can use either a parallel Gray code altitude input, or serial RS232 altitude input. Both of these interfaces are on the 24 way connector. If the altitude encoder you are using offers both, we recommend using the RS232 serial input. Serial formats allow a higher resolution altitude representation that can be AVIDYNE CORPORATION Page 11...

    The contacts can be easily removed using the Molex removal tool, or equivalent. This is pushed gently into the connector shell from the side opposite from the wire entry, and lifts the retaining tab from the stop, allowing the contact to be eased out by pulling on the wire.

  • Page 22: Antenna Installation

    To prevent RF interference, the antenna must be physically mounted a minimum distance of 3 feet from the AXP340 Mode S transponder. Electrical connection to the antenna should be protected to avoid loss of efficiency as a result of the presence of liquids or moisture.
  • Page 23 Allow a minimum separation of 300mm (12 inches) from an ADF antenna cable Keep the cable run as short as possible Avoid routing the cable round tight bends. Avoid kinking the cable even temporarily during installation. Secure the cable so that it cannot interfere with other systems Page 16 AVIDYNE CORPORATION...
