AXP340 Mode S Transponder. 1.2 Scope This document applies to the installation of the AXP340 Mode S Transponder. At the publication date of this manual the software version identifier for the AXP340 is 3.8 and the FPGA version identifier is 110613a. The software and FPGA versions are subject to change without notice.
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.

DO-260B which technically is a deviation from the ETSO. This deviation has been approved by EASA. 3.2 Physical Specifications (in Tray) Specification Characteristics Height 42mm (1.65”) 160mm (6.30”) Width Length 285mm (11.22”) Weight 2.8lbs. (1.35Kg) Page 4 AVIDYNE CORPORATION...
Issue AF 3.3 Installation Approval The conditions and tests required for the TSO approval of the AXP340 Mode S Transponder are minimum performance standards. It is the responsibility of those desiring to install this transponder on or within a specific type or class of aircraft to determine that the aircraft operating conditions are within the TSO standards.

If the aircraft does not have existing mounting provisions you may need to fabricate additional brackets to support the transponder tray. To support the optional ADS-B features a GPS receiver with an appropriate serial output is required. AVIDYNE CORPORATION Page 7...
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...
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...
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...
Audio output is up to 10 Volts peak-to-peak across the pair when driving a 600 Ohm load; actual level can be adjusted at installation Page 12 AVIDYNE CORPORATION...
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 14 AVIDYNE CORPORATION...
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...
Solder the inner shield to the inside of the connector body by applying a soldering iron to the body and running solder into the gap. Try to avoid excess solder heat on the connector body. Solder the outer shield to the outside of the connector body. Avoid excess solder heat on the connector body. AVIDYNE CORPORATION Page 17...

Slide heat shrink tubing forward (flush to connector) and heat to shrink the tubing. Complete the assembly by installing the bushing over the centre contact, and fitting the cap. Solder the cap in place in at least two places. Page 18 AVIDYNE CORPORATION...
The Circlip washer should be fitted with a set of Circlip pliers. The two Molex connectors should be passed through the openings in the rear of the tray, and then mounted firmly to the tray from the inside using the four M3 screws supplied. AVIDYNE CORPORATION Page 19...
These addresses are usually written as a 6 digit hexadecimal number, although you may also encounter one written as an 8 digit octal number. The AXP340 only understands the hexadecimal format, so you must first convert an octal number to hexadecimal. Page 20 AVIDYNE CORPORATION...
Press selector knob to accept and move to the next menu item. The Avidyne IFD440 and IFD540 use the Trig ADS-B protocol at 38400 bps. GPS receivers using the Garmin protocol run at 9600 bps. Panel mount GPS units with Aviation format outputs generally also run at 9600 bps.

The lighting bus check displays the voltage on the lighting bus to assist in verifying the correct operation of the lighting bus. 6.2.4 Temperature The internal temperature of the transponder may be accessed only in maintenance mode. This is for information only and does not provide any diagnostic value. Display is in degrees Celsius. AVIDYNE CORPORATION Page 23...
To assure that the interface is fully operable the aircraft should be tested with the transponder in normal operating mode, with the GPS receiver operating correctly, and a ramp test of the transmitted parameters completed. Page 24 AVIDYNE CORPORATION...
GPS position is not valid or the GPS interface is not correctly configured. Whenever a valid position is received by the transponder and the transponder is in any mode other than Standby, ADS-B Extended Squitters should be observed on the transponder test set. AVIDYNE CORPORATION Page 25...
The transponder is on, but will not reply to any interrogations. When airborne, the transponder should always be set to ALT unless otherwise directed by Air Traffic Control. Page 26 AVIDYNE CORPORATION...

Depending on the nature of the problem, your transponder may not be replying to interrogations. Note the message on the screen and pass that information to your avionics maintenance organisation. The WARNING message should clear when the event has cleared. Press CLR to clear the message at any time; Page 28 AVIDYNE CORPORATION...
The AXP340 is certified to operate correctly down to -25C, but at low temperatures the display may be impaired. On a cold day you may need to wait for the cockpit to warm up to ensure normal operation. AVIDYNE CORPORATION Page 29...
Issue AF 9. Continued Airworthiness Other than for periodic functional checks required by the regulations, the AXP340 Mode S transponder has been designed and manufactured to allow “on condition maintenance”. This means that there are no periodic service requirements necessary to maintain continued airworthiness, and no maintenance is required until the equipment does not properly perform its intended function.

In all cases, uncompensated latency due to the transponder is less than 10 milliseconds. Analysis of the system latency should add this to the latency of the GPS system and the transmission time of the position data from the GPS to the transponder to determine the overall latency.
