Vehicle ID
The vehicle ID is stored in 4 registers giving a total of 64 bits or 8 bytes. The first byte is the tag crc, register 35
through 37 are the 48-bit unique serial. Register 38 shows the family code and crc of the device. When the Rack is
still searching for a tag, or when there is no valid ground verification, all registers will contain the value 0xFFFF.
When there is no valid tag found all registers will contain the value 0x0000.
