@ Description
_8136_P_Initial
:
This function is for setting the encoder counter's clockand
enabling pulse output functions. Tthis function must be used to
enable pulse input and output.
_8136_P_Set_Output_Type
:
There are 3 pulse output types in PCI-8136. This function is for
configuring pulse output type by a value. Write a value 0 for pulse/
direction type. Write a value 1 for CW/CCW type. Write a value 2
for A/B phase type.
_8136_P_Set_Input_Type
There are 3 encoder counter input types in PCI-8136. This func-
tion is for configuring encoder counter input type. Write a value 0
for A/B phase type. Write a value 1 for CW/CCW type. Write a
value 2 for pulse/direction type. When setting A/B phase type, the
multiplier value must be assigned by this function.
