c)
Pin 17 receives external 5V DC voltage to provide power supply for inside isolate chip
of DB25, thus the input and output signals are valid.
d)
Pin 18 is the start signal of the MO. Pin19 is the input for the optical output signal. The
electrical level for both Pin18 and Pin19 are 5V. Before turning on Pin 19, MO signal
must be switched ON, in other word, the signal of Pin 18 must be ahead of Pin 19 at
least 5 ms, and otherwise the laser machine may be damaged.
e)
Pin 20 provides control of the frequency. The frequency range should be 1kHz~2000
kHz, depends on the varying power levels of different laser machines.
ATTENTION: The frequency signal must be ahead of the EM signal at least 5 ms,
otherwise the laser machine may be damaged.
