To prevent unpredictable results, the array size values for the RangeSize, Values100kSize, and
Values1MSize must be set to 8, as shown in the figure above.
See Example 1: Cable compensation
is done.
The returned arrays are arranged in the order shown in the following table.
Reading_rate valid inputs

If the file defined for CabCompFile does not exist, or there is no path specified (null string), the
default compensation parameters are used. When entering the path, use two backslash (\\)
characters to separate each directory. For example, if your cable file is in
C:\calfiles\590cal.dat, you enter the following:
C:\\calfiles\\590cal.dat
If a switch matrix to route signals is being controlled by a connection action (for example, connect),
there is no need to connect InputPin and OutPin. Set these parameters to 0.
The return values from status can be:
•
0: OK.
•
-10021 (COMP_FILE_NOT_EXIST): The specified compensation file does not exist.
•
-10022 (KI590_NOT_IN_KCON): There is no CMTR defined in your system configuration.
