Speed Limits
The Antares 4G supports up to 10 configurable speed thresholds (S00–S09).
Configuration
Use the GS command:
>SGS{NN}{C}{SPEED}<
Speed is in mph × 10 (4 digits):
| Speed | Value |
|---|---|
| 50 mph | 0500 |
| 80 mph | 0800 |
| 100 mph | 1000 |
| 120 mph | 1200 |
Example:
>SGS0010800< ← S00 activates when speed > 80 mph
>SGS0110200< ← S01 activates when speed > 120 mph
Speed Signals
| Signal | Description |
|---|---|
S00–S09 | User speed limit signals |
G27 | General over-speed signal |
Example: Speed Alert
Configure an event to report when speed exceeds 80 mph:
# 1. Set speed threshold
>SGS0010800<
# 2. Define event for S00 rising edge
>SED10NA0;S00+< ← Report when speed exceeded
# 3. Define event for S00 falling edge (optional)
>SED11NA0;S00-< ← Report when back under limit
Counter Integration
Track total time spent over speed with the built-in CS counter:
>QXACSV<
>RXACSV000001909< ← 1909 seconds over speed
Add to reports with XAEF: >SXAEFA;CS<
