Channel Number2
Total Length11 bytes

If Data1 = 1,2, or 3
Start method = Data1
Stop method = Data2
Pretrigger loop exit = Data3
Pretrigger time (minutes) = Data4
Postrigger time (minutes) = Data5
Autostart source = Data6
Autostop source = Data7
Lowest buffer value = Data8 x 2^8 + Data9

Start methods:

        1   	Button press
        2   	Autostart
        3   	Starting pretrigger loop (On VIDEO4: DVR serial command from PC commander   OR   Remote RT serial command from DASH)

Stop methods

        1   	Button press
        2   	Autostop condition met
        3   	post trigger expired
        4   	low battery voltage
        5   	low buffer space
        6   	GSM command
        7   	Disk full
        8   	DVR serial command from PC commander
        9   	Remote RT serial command from DASH
        10   	4 GB file limit exceeded (pDrive only)
        11      Loop size exceeded
        12      CAM disconnect

Pretrigger loop exit

        1   	Button press
        2   	Autostart

Autostart and autostop values

        1-8 	ADC channels 1-8
        15 	Lateral g-force
        16   	Longitudinal g-force


If Data1 = 4
Same as above, except Start method is given by top 4 bits of Data2. Stop method is bottom 4 bits of Data2.

If Data1 = 5
Data2 gives feedback on why trying to add a track marker failed on a logger. Valid reasons are:

  1. Marker already exists at this location
  2. Too many markers defined
  3. Not currently logging data
  4. No card inserted
  5. GPS data is too inaccurate
  6. Correct GPS data is not available

We should send error 5 if the positional accuracy is > threshold
We should send error 6 if we are not receiving GPS position, time and heading as required, so this would lead the user to know that the DL1 was not set up correctly.


If data1 = 6
Data2 = status

The status byte is a bit field with the following bits (bit 0 is the LSB, bit 7 is the MSB):
bit 0: GPS module(s) detected OK (no GPS module error set)
bit 1: IMU detected OK (no IMU error set)
bit 2: GPS 1 lock
bit 3: GPS 2 lock
bit 4: Carrier lock
bit 5: RTK lock
bit 6: INS initialised
bit 7: INS converged


Data3/4/5/6 = Kalman filter convergence , float
Data7/8 = number of measurements that were rejected by the kalman filter
Data9 = DSP load, 0 to 100

Special Case:
Data2/3/4/5/6/7/8 = 0
Data9 = LAP Marker file status

  1. Not checked yet (No GPS lock yet)
  2. LAP file loaded successfully (Only one LAP file found)
  3. No LAP files on disk
  4. Failed to load the only one LAP file
  5. Failed to access only one LAP file
  6. LAP file loaded successfully (DEFAULT.LAP file found: only in pDrive)
  7. LAP file loaded successfully (Matching file found in the range)
  8. No matching file found in the range


If data1 = 7
Data2/3 = Roll gyro bias, Signed 16 -32.768 degrees to 32.767 degrees
Data4/5 = Pitch gyro bias, Signed 16 -32.768 degrees to 32.767 degrees
Data6/7 = Yaw gyro bias, Signed 16 -32.768 degrees to 32.767 degrees
Data8/9 =Yaw gyro scale, Signed 16 -3.2768 degrees to 3.2767 degrees

If data1=8
Data2/3 = Longitudinal accelerometer bias, Signed 16 -32.768 m/s^2 to 32.767 m/s^2
Data4/5 = Lateral accelerometer bias, Signed 16 -32.768 m/s^2 to 32.767 m/s^2
Data6/7 = Vertical accelerometer bias, Signed 16 -32.768 m/s^2 to 32.767 m/s^2

If data1=9
Data2= Product type
1= DL1 MK3/CLUB/PRO
2= DASH2 PRO
3= RT Live

  4= VIDEO4HD

Data3/4/5 = Main application version, MSB first
Data6 = Bootloader version LSB
Data7 = Hardware version

If data1 = 10
Data2/3/4/5 = good messages seen on serial port 1 Data6/7/8/9 = checksum errors on serial port 1


If data1 = 11
Data2/3/4/5 = good messages seen on serial port 2 Data6/7/8/9 = checksum errors on serial port 2


If data1 = 12
Data2/3/4/5 = good messages seen on CAN port 1 Data6/7/8/9 = errors on CAN port 1


If data1 = 13
Data2/3/4/5 = good messages seen on CAN port 2 Data6/7/8/9 = errors on CAN port 2


If data1 = 14
Data2/3 = hardware errors on serial port 1 Data4/5 = hardware errors on serial port 2 Data6/7 = hardware errors on CAN port 1 Data8/9 = hardware errors on CAN port 2


if data1 = 64
data 2 - data 9 are the characters of the name/alias of the current driver
