How it works
From ETS2 telemetry → DTCO LCD → VTC LIVE portal
The overlay runs on your PC and reads ETS2 data through a local telemetry server. It then converts that data into tachograph states (Driving/Break/Rest/Work), logs events, creates printouts and optionally sends live updates to the VTC portal.
Step 1
Telemetry server runs locally
The overlay connects to your local endpoint:
http://127.0.0.1:25555/api/ets2/telemetry
If telemetry isn’t running, the overlay shows a red dot and cannot read speed/state.
Step 2
Overlay extracts live data
- Speed (km/h)
- Engine state
- Heading
- Location (if provided by telemetry)
Step 3
Tachograph logic updates every moment
States
- Driving when speed is above threshold
- Break only after being stopped long enough (armed)
- Rest while stopped but not armed
- Work manual mode (toggle)
EU break engine
- 4h30 driving block
- 45m break required
- Split allowed: 15m + 30m
- Missed break logs an infringement
Step 4
Events & printouts
Overspeed and infringement events are stored persistently. Printouts are generated on demand and saved locally for VTC evidence and roleplay.
Step 5
DTCO LIVE (VTC side)
If LIVE is enabled for your device and your activation is ACTIVE, the overlay sends live status to the portal for fleet dashboards and monitoring.
