e) PIN 10、13、14、15、24、25 are all digital GND.
f) PIN 20 is the pulse repeating rate signal(PRR, TTL level). If the PRR need to be
changed during the work, it must be changed 5ms earlier than the EM signal turning
into high.
g) PIN 22 is the guide laser (red diode)on/off signal. High level switch on the guide laser
while low level switch off the guide laser.
