System Description and Installation Manual for MXS ICD10004-01 Overview The MXS transponder performs the following basic functions:     Transponder: o Interacts with air traffic control (ATC) by transmitting and receiving standard secondary surveillance radar pulses per ICAO requirements. The transponder replies to ATCRBS interrogations with a squawk code and pressure altitude data.

System Description and Installation Manual for MXS  ICD10004-01 Flight computer communication is via a proprietary protocol via RS-422, RS-232 or Ethernet.
PAGE 10
System Description and Installation Manual for MXS ICD10004-01 Installation Installation of the MXS consists of:       Mounting MXS with required 2.
PAGE 11
System Description and Installation Manual for MXS     ICD10004-01 The MXS requires a 2.0°C/Watt heat sink at full power above 40°C ambient. Actual heat sink needs are dependent on temperature of operating environment and power load. MXS is designed in such a way that its case conducts thermal load to the aircraft frame. It can be firmly mounted directly to the aircraft or to other components within the aircraft. MXS should be mounted with the non-labeled side facing the heat sink.

The cable should be built according to standard A-A 59569A.

System Description and Installation Manual for MXS ICD10004-01 antenna connects to the left connector and the bottom antenna connects to the right connector. Whenever power is supplied to the MXS, a 50-ohm load should be provided to both SMA connections. Ensure that the antenna(s) selected provide a 50-ohm termination for the MXS. If only one antenna is used, replace the top antenna with a 50-ohm termination rated for 5W minimum.
PAGE 14
System Description and Installation Manual for MXS     ICD10004-01 Diversity installations are supported. Antennas should be mounted as near as possible to the center line of the fuselage. The bottom antenna should be mounted on the underside of aircraft fuselage, nominally at the wing root. Antennas should be located to minimize obstruction to their fields in the horizontal plane.
PAGE 15
System Description and Installation Manual for MXS 6. ICD10004-01 Routing and connecting the antenna cable Attach your antenna cable to the bottom antenna SMA connector shown in Figure 0-3Figure 3-3. A suitable antenna cable consists of a male SMA connector, a length of co-axial cable, and a suitable connector for your antenna. For example, if you are using a simple monopole antenna with a BNC female connector, your antenna cable will need a BNC male connector.
