Power Input: 10 – 32 VDC
Standard: IEC 62287-1, ITU-R M.1371

⚓ Seanav Marine UAE NAVCOM & AIS Service Hub:

1. Technical Service, Repair & Maintenance Scope

The easyTRX2S Class B AIS is a high-precision marine AIS transponder engineered for demanding offshore and commercial shipping applications. Routine maintenance and specialized component-level repair ensure uninterrupted VHF data exchange on 161.975 MHz (AIS 1) and 162.025 MHz (AIS 2) per ITU-R M.1371.

🔧 RF Circuitry & Transceiver Repair

  • Internal VHF power amplifier (PA) transistor inspection and power level tuning
  • Receiver sensitivity measurement (-107 dBm threshold verification)
  • VHF Antenna VSWR matching and coaxial cable loss diagnostics
  • DSC Channel 70 receiver tuning and telecommand response tests

🔄 MMSI Reprogramming & Password Reset

  • Flag change static data reprogramming (9-digit MMSI, 7-digit IMO, Call Sign)
  • Internal GNSS antenna position offsets entry (Dimensions A, B, C, D in meters)
  • Dealer password recovery and supervisor security PIN unlock
  • Dedicated service interface using Weatherdock easyTRX2S Setup Tool

📋 Annual Radio Survey & APT Testing

  • IMO MSC.1/Circ.1252 annual performance testing with Futronic MKII / Argonaut
  • RF forward/reflected power measurement (tolerance within ±1.5 dB)
  • Transmitter frequency tolerance calibration (within ±500 Hz)
  • Pilot plug signal amplitude and polarity compliance verification

🔌 Bridge Sensor & Pilot Plug Interfacing

  • Gyrocompass HDT / THS heading input configuration at 4800 / 38400 baud
  • ECDIS and ARPA Radar target tracking interface (AIVDM / AIVDO sentences)
  • VDR dual-stream output synchronization
  • Standard IEC 61162-2 pilot plug interface validation

2. Reprogramming Procedures & Dealer Configuration (easyTRX2S Class B AIS)

During vessel flag registration change, sale, or structural alteration, the static data on the easyTRX2S Class B AIS must be updated strictly by certified marine electronics engineers. Modifying protected static parameters requires authorized dealer access:

  1. Connection & Diagnostic Hookup: Connect the Seanav service PC to the maintenance port or front-panel service interface using the dedicated interface adapter.
  2. Service Software Initiation: Execute Weatherdock easyTRX2S Setup Tool with authorized engineering credentials to bypass user-level locks.
  3. MMSI Re-initialization: Clear the existing 9-digit MMSI from the transponder EEPROM and input the newly assigned Maritime Mobile Service Identity.
  4. Static Vessel Details Entry: Input the official IMO ship identification number, radio Call Sign, official vessel name, and ITU ship type / cargo classification.
  5. GNSS Offset Alignment: Enter exact physical measurements (Offsets A, B, C, D) from the internal GPS antenna to the bow, stern, port, and starboard hull edges.
  6. Verification & Test Transmission: Conduct an interrogation cycle with our calibrated AIS test box to verify that updated static data packages (Message 5 / Message 24) broadcast accurately over the VDL.
