A1.2. Real-Time Output Data – Binary Format (to Serial Port)
If OutFormat = BINARY , the ADV sends a block of data to the serial port after each velocity sam-
ple. The size of the binary-format data block varies depending on which optional sensors (com-
pass/tilt, temperature, pressure) are installed. Section A1.2.1 describes the data block formats.
A1.2.1 Block Structures
This section defines the format of each type of binary data block structure in the “C” program-
ming language. There are four possible types of output blocks.
• ADV data with no optional sensors installed.
• ADV data with the optional compass/tilt sensor installed.
• ADV data with the optional temperature and/or pressure sensors installed.
• ADV data with the optional compass/tilt sensor and with the optional temperature and/or
pressure sensors installed.
Notice that each of the following structures uses a checksum to ensure accurate data transmis-
sion. See §A1.2.2 for details on computing the checksum.
ADV data with no optional sensors installed
The structure
ADVNoSensors (below) is used when no optional sensors are installed (18 bytes).
typedef struct {
unsigned char Id; /* Data record ID, 0x81 */
unsigned char Nbytes; /* Number of bytes in record = 18 */
unsigned int SampleNum; /* From start of data collection */
int XYZVel[3]; /* x/y/z vel in 0.1 mm/s */
unsigned char Amp[3]; /* Amplitude 1, 2, 3 */
unsigned char Cm[3]; /* Correlation 1, 2, 3 */
unsigned int ChkSum; /* 2 byte checksum of preceding 16 bytes */
} ADVNoSensors;
