NOTE For the GPS PPS signal, pulse width is recommended to be over 1 ms, and the cycle is 1 s (rising edge to rising edge)
NOTE Before connecting or disconnecting an external GPS signal (either using the cable's GPS wire or via the connection box's GPS port),
make sure the LiDAR is powered off. If the LiDAR has to stay powered on, make sure to:
· ground yourself in advance · avoid touching the GPS wire or GPS port with bare hands
