Field Size (bits) Bit Range Description Breakdown
Header (10 Bytes)
Start byte 8 0–7 Starting character $ (ASCII value 36)
Data length 12 08–19 2-byte length of the data following the header
Number of data packets 5 20–24 Number of packets (0–32) 0–32
IMEI 50 25–74 Unique device identifier
Packet type 5 75–79 Type of packet 00 - Device Info
Data
Time 32 UTC Timestamp UTC time in seconds
Time Zone 8 Timezone in quarter-hours (e.g., 22 = +5:30), quarter-hour increment means each unit represents 15 minutes. The value 22 represents 22 quarter hours. Ranges from -48 to 56, negative timezone to 2's complement representation eg: 22 (+5:30) → 22×15=330 minutes → 330÷60=5.5 hours → 5 hours and 30 minutes
ICCID 160 20 Bytes, Character string 8991000903297069053F
VID 32 4 Bytes, Character string TRAN
CELLULAR_MODULE_FV NAME 40 5 Bytes, Character string TSPJT
CELLULAR_MODULE_FV VERSION 80 10 Bytes, Character string XX.YY.ZZZZ
CELLULAR_MODULE_FV BUILD NO 40 5 Bytes, Character string YYDDD
MCU_APP_MODULE_FV NAME 40 5 Bytes, Character string TSPJT
MCU_APP_MODULE_FV VERSION 80 10 Bytes, Character string XX.YY.ZZZZ

Tail(2 Bytes)
End Character 8 0–7 Starting character * (ASCII value 42)
CRC 8 8–15 8-bit XOR CRC of data starting from $ to * (excluding $ and *)
