Eng Meet Train Embarkation V110 V2412 Install Guide

Title: Track Level Update: Installing Embarkation Protocols v110 & v2412 on the "English Meet Train"

Posted by: RailTech Admin Date: October 26, 2023 Category: Rolling Stock Software / PIS

If you are working the English Meet Train (EMT) fleet this quarter, listen up. We have just pushed the mandatory firmware cascade for the passenger embarkation and wayfinding modules.

Whether you are at the depot or doing a hot-swap at the terminus, here is the walkthrough for installing v110 and v2412 onto the main head unit. eng meet train embarkation v110 v2412 install

2. Pre-Installation Checklist (V110 & V2412)

Before beginning the install, ensure the following:

| Item | Specification | |------|----------------| | Hardware | Dejero V110 Chassis (Firmware ready) + V2412 LTE/5G module | | Tools | Phillips #1 screwdriver, ESD wrist strap, Ethernet cable (Cat6) | | Software | v2412_firmware_package.bin (downloaded from Dejero Care portal) | | Network | Stable internet connection (min 10 Mbps for download) | | Credentials | Admin access to V110 (default: admin/admin or SSO) |

Warning: The V2412 module is sensitive to power fluctuations. Always ground yourself and power off the V110 before physical handling. Part 4: Integrating ENG MEET v110 with Embarkation

Part 4: Integrating ENG MEET v110 with Embarkation v2412

The meet-train-embarkation pipeline must be synchronized. The eng meet train embarkation sequence follows:

  1. Train arrives at station → MEET v110 detects platform occupancy.
  2. MEET triggers embarkation v2412 via REST call POST /embark/begin.
  3. Embarkation v2412 handles door control, passenger flow, and load balancing.
  4. On completion, embarkation signals back to MEET: status=ready_to_depart.

1. Objective

The objective of this report is to document the installation, configuration, and initial validation of the Engineering Meet Train Embarkation (ENG-MTE) system software versions v110 and v2412 across designated embarkation control units.

Part 1: Obtaining the Installer Packages

The deployment involves two distinct versioned artifacts: Train arrives at station → MEET v110 detects

Download from the official engineering portal (requires RAILDEV credentials). Verify SHA-256 checksums:

sha256sum ENG_MEET_v110.zip  # Expected: a1b2c3...
sha256sum EMBARK_v2412.bin   # Expected: 4d5e6f...

Part 5: Troubleshooting Common Failures

Even with strict adherence, issues occur. Here is the v110/v2412 error matrix:

| Error Code | Message | Solution | | :--- | :--- | :--- | | E-0x41F2 | Embark buffer mismatch | The v2412 package is 12MB; v110 requires the "large_payload" flag. Re-run with --allow_large_buffers | | E-0x88B1 | Meet Train timeout | EMI interference. Use ferrite clamps on the MVB cable. Reset the embarkation gateway via physical button S3. | | E-0xAE44 | v2412 signature invalid | The host PC clock is skewed. Sync via NTP. v2412 checks timestamps. | | Bus Fault | Segmentation fault in eng_sandbox | Run export LD_LIBRARY_PATH=/opt/rail_eng/v110/lib before launching. |
