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 (110 Bytes)
Time 32 80-111 UTC Timestamp UTC time in seconds
Time Zone 8 112-119 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
