The lidar's GPS data interface is compatible with a variety of GPRMC formats, as long as:
<01> is the hour, minute, and second information
<09> is the date information.
For example, the following two formats are both acceptable:
$GPRMC,072242,A,3027.3680,N,11423.6975,E,000.0,316.7,160617,004.1,W*67
