Single Return Mode
The ranging data generated by one round of firing is stored in one block. The calculation of each Block's end time is as follows:
Block
End Time (μs)
Block 10
t0 - 28.58
Block N
t0 - 28.58 - 55.56 * (10 - N)
Block 3
t0 - 28.58 - 55.56 * 7
Block 2
t0 - 28.58 - 55.56 * 8
Block 1
t0 - 28.58 - 55.56 * 9
Dual Return Mode
The ranging data generated by one round of firing is stored in two adjacent blocks: the odd number block is the last return, and the even number block is
the strongest return. If the last and strongest returns coincide, the second strongest return will be placed in the even number block.
Therefore, Block 1 & Block 2 have the same firing time, Block 3 & Block 4 the same firing time, and so on.
Block
End Time (μs)
Block 10 & Block 9

Block 2 & Block 1
