Quick answers

Stock Traccar port?

5086 TCP and UDP.

Header?

Little-endian 0x4040 (@@).

GPS SC type?

0x4001 among a large OBD/alarm type set.

Castel on Traccar port 5086 listens on TCP and UDP. Frames are little-endian length-based; header short 0x4040 (@@) leads into versioned SC or CC bodies. SC covers login 0x1001, heartbeat 0x1003, GPS 0x4001, PID/OBD 0x4002/0x4005, alarms 0x4007, fuel 0x400E, comprehensive 0x401F. Engine stop/resume exist in Traccar’s encoder — Traxelio still marks positions_only.

SC/CC binary on 5086

AVL301 on neighboring 5085 is L/H/$. Cellocator on 5033 uses MCGP. Castel’s @@/0x4040 plus OBD-heavy SC map is the differentiator.

Catalogue stance

Stock Traccar reference. No Traxelio full-support or immobilizer delivery claim.

Setup walkthrough

  1. 1

    Open 5086 TCP or UDP to match firmware

    Castel registers both; mismatch drops packets.

  2. 2

    Capture @@ / 0x4040

    Wrong magic means you are on AVL301 or Cellocator instead.

  3. 3

    Start with login 0x1001 / GPS 0x4001

    OBD PID frames are secondary after a live GPS type.

  4. 4

    Keep immobilizer expectations offline

    Traccar encoder hooks ≠ Traxelio command product.

Common troubleshooting

Aimed at 5085 AVL301

L/H/$ will not parse Castel — use 5086.

OBD without GPS

PID types enrich telemetry; maps still need 0x4001 (or comprehensive) GPS content.

Assuming engine stop works here

Catalogue remains positions_only on Traxelio.
