| triggers or events | event label | event detail |
| GPS | GPSx | one or more of: d>dist, a>b, hchg>c, t>timer, accela>b, decela<b |
| IDLE | IDLEx | one of: START or END |
| Input condition | GPIOx | one or more of: inab where a is input number 1 to 6 and b is A=analog or D=digital:(one of c<HIGH, c>LOW, c~HIGH (digital), or c<dV, c>dV, c~d (analog)), ipchg=<IP>, t>timer |
| IGNITION | IGNx | one of: ON or OFF |
| OBDII-J1939 | OBDx | one or more of p<param>:curValue<setValue, curValue>setValue, p<param>=setValue (no transition) OR p<param>:curValue=setValue (transition), t > timer |
| POWERUP | PUPx | |
| VOLTAGE LEVEL | VCCx | one of: a.aa>b.bbV ,a.aa<b.bbV |

| SWIPE REPORT or IBUTTON | RFIDx | |
| EXTERNAL EQUIP (saltspreader, ETC) | EXTz |
For cases where multiple conditions can exist the x will define which condition triggered (1 thru 8), ie, gpscond 1 2 30 50 would cause GPS1 to be included as the event message. For external equipment z would define the type of external equipment, ie EXT1 is for chlorobyte saltspreader.
For GPIO events:
- digital values are based on the voltage value dropping below 2 V or going above 3V, these values are fixed and cannot be changed.
- ~ indicates a transition from LOW to HIGH or HIGH to LOW trigger for both Digital and Analog
Where:
hhmmss.ss is the UTC time in hours, minutes, seconds, and decimal seconds
v is the data validity flag: A = valid current data, B = valid stored data, V = invalid current data, W = invalid stored data
ddmmyy is the day, month and year
xxxxxxxxxxxxxxx is the gateway’s unique 11 or 15 digit ESN or IMEI number
Note: For non-cellular devices (Wi-Fi) the gateway unique ID is generated automatically from the LAN1 MAC address.
yyyyyyy is the Event description, see table above
hh is the message checksum
Examples:
Message containing OBD condition 1:
cmd obdcond 1 1 0 0 'p1>10' 'p2>100'
