  • Page 5: Introduction

    ME-183 NAV Interface (ME-183 NAV). The ME-183 NAV relays latitude and longitude position data to the ELT for incorporation into the 406 MHz Search and Rescue (SAR) satellite message. The ME-183 NAV is designed as a retrofit accessory for Artex ME406 Series ELT installations.

  • Page 6: System Description

    Figure 1-2: ME-183 NAV Interface System Integration Block Diagram Installation of the ME-183 NAV requires an on-board navigation system (GPS) supporting NMEA 0183 output, in addition to an Artex ME406 ELT system. The GPS receives satellite signal information, calculates latitude and longitude position, and sends the position data to the ME-183 NAV.

  • Page 7: Compatibility

    • The ELT transmits a default message if it does not receive valid position data. • Compatibility The ME-183 NAV is compatible with the following Artex ME406 Series ELTs: ME406 ELT – 453-6603 • ME406 HM ELT – 453-6604 •...

  • Page 8: Integration

    The ME-183 NAV is compatible with NMEA 0183. Artex recommends the use of a dedicated GPS data output channel for the ME-183 NAV. Data Output Requirements...

  • Page 9: Overview

    OVERVIEW This section provides an installation overview and should be reviewed by personnel performing the work. Regulatory Requirements TSO C126, Paragraph D “The conditions and tests required for TSO approval of this article are minimum performance standards. It is the responsibility of those desiring to install this article on a specific type or class of aircraft to determine that the aircraft installation conditions are within the TSO standards.

  • Page 10: Installation

    The ELT must be programmed with a long message (location protocol), if necessary, before installing the ME-183 NAV. ELT reprogramming may be accomplished by an authorized service center or by using an Artex ME406 Reprogramming Adapter (455- 6600). Installation Instructions The following subsections provide installation guidelines and instructions.

    Make a “Drip Loop” in the remote switch harness connection to the ME-183 NAV • to divert moisture from the DB15 plug. NOTE: A drip loop is an extra length of cable formed into a U-shaped bend just before the plug. Water or other fluids flow down to the bottom of the loop and drip off, diverting them away from the plug.

    12. Fit the other housing half into place, taking care to align the thumbscrews, bracket washers, grommet, and plug. 13. Screw the housing halves together using the long, fully-threaded screws and nuts supplied as part of the D-Sub housing kit. 14.

  • Page 16: Me-183 Nav Interface Testing

    ME-183 NAV INTERFACE TESTING The purpose of this testing is to verify integrity of the ELT system after ME-183 NAV installation. This section also discusses the option of verifying position data transmission using a beacon test set. Self-Test The following procedure initiates an ELT self-test routine to verify integrity of the ELT system.

  • Page 17: Position Data Verification

    G-switch loop error ELT battery usage over one hour Position Data Verification Artex does not require this test be performed; any problem with received position data will be indicated by the 5-pulse error (Table 5-1) during self-test (Subsection 5.1.2). CAUTION: Artex only recommends this test be performed if the 406 MHz signal can be properly shielded inside a screen room or container.

  • Page 18: Periodic Maintenance

    PERIODIC MAINTENANCE The following subsections describe periodic maintenance and testing requirements and procedures for the ME-183 NAV. Comply with these requirements at the same time periodic maintenance and testing is performed on the ELT system. Inspection WARNING: It is possible to inadvertently activate the ELT when working around the ELT and/or removing and installing the ME-183 NAV.
