B.1 Driver API Guide
In Runtime folder, on IVH9K2.h :
_DLL_IMPORT_ definition is used on LoadLibrary API for IVH9K2.dll.
IVH9K2_EXPORTS definition is used on IVH9K2.dll building.
BOOL Initial(BYTE Isolate_Type, BYTE DIO_NPN)
Initial machine for DIO, watchdog timer, and POE
Isolate_Type : DIO type
1 : Isolated DIO;
0 : Non-Isolated DIO
DIO_NPN : DI/DO type
1 : PNP (Source) mode for European rule;
0 : NPN (Sink) mode for Japanese rule
Return :
TRUE (1): Success;
FALSE (0): Fail (Driver not exists, or initial error (version is too old, or
machine not match))
BOOL GetDIO1Config(BYTE *Isolate_Type, BYTE *DI_NPN, BYTE *DO_
NPN, WORD *Mask)
BOOL GetDIO2Config(BYTE *Isolate_Type, BYTE *DI_NPN, BYTE *DO_
NPN, WORD *Mask)
Get DIO configuration (by variable)
Isolate_Type : DIO type
1 : Isolated DIO;
0 : Non-Isolated DIO
DI_NPN ([7:0]) : DI type, pin setting by hexadecimal bitmask
1 : PNP (Source) mode for European rule;
0 : NPN (Sink) mode for Japanese rule
DO_NPN : DO type
1 : PNP (Source) mode for European rule;
0 : NPN (Sink) mode for Japanese rule
Mask ([15:0]) : In/Out, pin setting by hexadecimal bitmask
