Data Sheet

V 1.2, July 2018

2nd case: The last bit of the preceding protocol is cut off.

The time between 2 consecutive protocols is no longer sufficient and a new increment of the encoder occurs, while

the last bit of the preceding protocol is still being transferred. At this moment the new protocol begins again with

the constant-time output offset of the length tp. However now it is realized in the sensor that a bit transfer is still

running. This is completely transmitted within the currently running output offset. After the output offset ends, the

initial bit follows with tp/2, then the speed pulse, etc.
