IC Command

The IC command (Identification Code) enables driver session management through identification codes, tracking who operates the vehicle, for how long, and what distance they cover.

What is it for?

👤 Identify drivers via iButton, RF433 or Bluetooth
⏱️ Control work shifts with work/rest time tracking
📊 Usage statistics (duration, distance, idle time)
🔐 Vehicle access control with authorized codes
📱 Operation modes for different work types

Syntax

Operation	Command	Description
Start session	`SICcode,mode`	Opens session with code and mode
Change mode	`SIC,mode`	Changes active session mode
Close session	`SIC*`	Ends current session
Query	`QIC`	Gets active session data

QIC Response


RIC code,mode,datetime,duration,idle,movement,distance,slot

Field	Format	Description
`code`	16 chars	Driver identifier
`mode`	1 char	Identification source (N=iButton/OneWire, R=RF433)
`datetime`	DDMMYYHHMMSS	Concatenated session start date and time (12 digits)
`duration`	8 digits	Total session time in seconds
`idle`	8 digits	Time with IGN OFF in seconds
`movement`	8 digits	Time with IGN ON in seconds
`distance`	10 digits	Distance traveled in meters
`slot`	4 digits	ICL slot (0000-0099) that opened the session

IC Signals (Triggers)

Signal	Event	Description
`IC00+`	Session started	New session opened
`IC01+`	Mode change	Session mode modified
`IC02+`	Valid user	Code found in ICL list
`IC03+`	Invalid user	Code NOT authorized

IC signals do not support negative edges or conditional use in TRG.

Basic Examples

Start session with iButton


>SICAA01234567890123,0<
// Response: RIC AA01234567890123,N,291224143022,00000000,00000000,00000000,0000000000,0003

Query active session


>QIC<
// Response: RIC AA01234567890123,N,291224143022,00003600,00001200,00002400,0000045000,0003

Interpretation:

Field	Value	Meaning
Code	AA01234567890123	Driver ID
Mode	N	Source: iButton / OneWire
Start	291224143022	29/12/2024 14:30:22 (concatenated datetime)
Duration	00003600	3600 s = 1 hour total
Idle	00001200	1200 s = 20 min engine off
Movement	00002400	2400 s = 40 min running
Distance	0000045000	45000 m = 45 km traveled
Slot	0003	ICL slot that opened the session

Close session


>SIC*<    // Ends session and saves statistics

Change mode during session


>SIC,1<   // Changes to mode 1 while maintaining session

Authorized Code Management (ICL)

To manage the authorized code list, use the ICL Command:


>SICL00 AA01234567890123<    // Load code at position 00
>QICL00<                      // Query code
>SICL00*<                     // Delete code

ICL slot in the response (v1.09.23)

From firmware v1.09.23, the RIC response appends at the end the ICL list slot that opened the session, formatted as 4 digits (0000-0099). The field is additive: it appears after the distance.


>QIC<
>RIC AA01234567890123,N,291224143022,00003600,00001200,00002400,0000045000,0003<
// ...,distance=0000045000, ICL slot=0003

Applies to QIC, SIC and SIC* responses.

With no active session, RIC comes back bare (no fields, no slot):


>QIC<
>RIC<

Limitations

Parameter	Value
Simultaneous sessions	1
Storable codes (ICL)	100 (00-99)
Code length	16 characters
Persistence	⚠️ Volatile (lost on restart)

Sessions are lost on device restart. To maintain records, send periodic reports with QIC or when closing sessions.
