Signal List

Signals are boolean conditions that can be used in event equations. A signal is either active (1/HIGH) or inactive (0/LOW).

F — Fixed System Signals​

These signals are set by the firmware based on hardware and system state.

SignalDescription
F00Ignition input active (IP1 LOW)
F01Valid GNSS fix available
F02Modem is in roaming mode
F03Modem registered on GSM network
F05Modem registered on GPRS/data network
F08SIM card is inserted and detected
F11Power Saving Mode session has ended
F12Accelerometer detects motion
F13External power (vehicle supply) present
F14Cellular cell ID has changed
F15Internal battery is low
F16Accelerometer detects hard motion / harsh event
F18Any iButton connected to OneWire bus
F19Authorized iButton detected
F21OneWire temperature exceeded critical threshold
F22No GNSS fix for more than 1 hour
F23GPS/cellular jamming detected

G — General System Signals​

SignalDescription
G00Safe Engine Cut-Off is enabled
G01SECO output has been activated
G02SECO sequence is running
G03Application has restarted
G04Jamming condition is persisting
G05Vehicle is idle (engine on, no movement)
G07Towing detected (motion without ignition)
G15Power Saving Mode has been scheduled
G16Power Saving Mode schedule was canceled
G27Speed exceeds configured limit
G35Excessive fuel consumption detected by Technoton thresholds
G36Technoton fuel sensor connected
G37Fuelling event detected by Technoton thresholds
G40Device has entered a configured region
G41Device has exited a configured region

A — Socket Signals​

SignalDescription
A00Socket 0 connected to destination
A01Socket 1 connected to destination

IP — Digital Input​

SignalDescription
IP1Digital Input 1 — active when voltage is 0–2 V

XP — Digital Outputs​

SignalDescription
XP1Digital Output 1 state
XP2Digital Output 2 state

S — Speed Threshold Signals​

10 configurable speed thresholds (S00–S09). Configure with the GS command.

SignalDescription
S00–S09Active when vehicle speed exceeds the configured threshold

J — Heading Signals​

10 configurable heading change thresholds (J00–J09). Configure with the XAGH command.

SignalDescription
J00–J09Active when heading change exceeds the configured delta

N — Acceleration Threshold Signals (Under Development)​

5 configurable GNSS-based acceleration thresholds (N00–N04). Configure with the XAGN command.

Each slot monitors the signed instantaneous acceleration (speed change per second) derived from consecutive GNSS speed readings.

SignalDescription
N00–N04Active when measured acceleration meets the configured signed threshold (mph/s)

Signal behavior:

  • Positive threshold (+): signal activates when acceleration ≥ threshold (hard acceleration).
  • Negative threshold (-): signal activates when acceleration ≤ threshold (hard braking).

TD — Time & Distance Signals​

10 configurable time and distance triggers (TD0–TD9). Configure with the TD command.

SignalDescription
TD0–TD9Active when the time or distance condition is met

TO — OneWire Temperature Signals​

10 temperature sensor threshold signals (TO0–TO9). Configure with XATO.

SignalDescription
TO0–TO9Active when temperature threshold is exceeded for sensor slot 0–9

Q — Authorized iButton Signals​

100 signals for individual authorized iButtons (Q00–Q99).

SignalDescription
Q00–Q99Active when the specific authorized iButton is connected

R — Region Signals​

360 region membership signals (R00–RZ9). Configure regions with the GR command.

SignalRangeCount
R00–R99Numeric100
RA0–RZ9Alphanumeric260

U — User Signals​

100 user-defined signals (U00–U99). Set manually via the SS command.

SignalDescription
U00–U99User-defined signals that can be manually set or cleared

Setting User Signals​

User signals (U00–U99) can be manually set or cleared:

>SSSU001<     ← Set U00 to 1 (active)
>SSSU000<     ← Set U00 to 0 (inactive)

Use the SS command (Signal Status) for querying and setting user signals.

C — Counter Threshold Signals​

100 counter signals (C00–C99). Active when the corresponding counter (GC command) reaches its threshold.

SignalDescription
C00–C99Active when the corresponding counter reaches its configured threshold

E — Event Signals​

100 event activation signals (E00–E99). Active when the corresponding event fires.

Signal Ban (XAQQ)​

The signal ban mechanism prevents a signal from firing too frequently. See XAQQ.

Signal Persistence (XASP)​

Signals can be configured with a delay before transitioning. See XASP.
