scaling value is 10. This means that if the actual value is 8.76, then this value is multiplied by 10 and truncated, thus the value sent
on the CAN bus will be 87. There is no rounding, so a sufficient high scaling factor must be used.

DLC = 0x06 (values above 0x06 are also valid, but Data bytes are not used)
Channel:
is the channel number that is requested and must be one of the following values
0x00 = channel 1
0x01 = channel 2
Scaling:
unsigned int – 4 bytes representing the scaling.
Example 1
Set scaling to 1000 for channel 1 - send the following command
Byte 0
Byte 1
Byte 2
Byte 3
Byte 4
Byte 5
Byte 6

As with all other parameters, the parameters must be saved if they are to be used automatically at startup.

DLC = 0x02 (values above 2 are also valid, but Data bytes are not used)
TO:
Timeout in ms. Default [0x20 = 32ms]
0x00 – 0xFF = timeout in ms that the sensor tries to send a message on the CAN Bus when sending the FFT. The timeout
is independent of the baud rate. The timeout is also independent of the CAN bus fault system which will go off bus if the
Transmit error counter reaches 255.
