6.4.1 External pulse command(Pt command)
The pulse command (Pt command) is provided by an external device. You should set PA01 to
0000 and then restart power to activate this parameter. There are three types of user-defined
input waveform. each type can be defined positive and negative logic. Positive logic means
the pulse is triggered by the rising edge, on the other hand, negative logic means the pulse is
triggered by the falling edge. The related parameters and setting methods are as follows:

z: The setting of input pulse filter.
z=0: the maximum input pulse
frequency is 500kpps.
(applicable frequency is between
200kpps-500kpps)
z=1: the maximum input pulse
frequency is 200kpps.
(applicable frequency is below
200kpps)
z=2: the maximum input pulse
frequency is 2Mpps.
(applicable frequency is between
500kpps ~2Mpps)
z=3: the maximum input pulse
frequency is 4Mpps.
(applicable frequency is between
2MPPS~4MPPS)
This parameter setting is valid after power cycling.
