U32 table_size)
 Purpose
Set the pulse data of user-defined pulse intervals for channel 1. The max. entry of position data
is 100000.
Note:
1. For the trigger retaining time, please refer to description of API

intervals.
Table_size U32
Number
Data size to be compared, which value has to be
identical to the array size of Pos_table. The max. is
100000.
 Example
U16 CardNo = 0;
I32 pos_table[4] = {1000,2000,3000,4000};
U32 table_size =4;
U16 status = _ECAT_Compare_Set_Channel1_Position_Table (CardNo, pos_table,
table_size);
